# 13F.ai > Ask your AI about insider, congressional and fund trades. Read-only data on US insider trades (SEC Forms 3/4/5), congressional stock trades, 13F institutional holdings, 13D/13G stakes, 8-K events, lobbying, federal contracts, patents, short interest, bills in Congress, corporate PAC donations, the IPO pipeline (S-1 / F-1 filings, pricings, withdrawals) and a crypto section (Congress crypto trades, spot bitcoin and ether ETF holders, corporate crypto treasuries, CME futures positioning, crypto super PACs) and published themes (company lists such as AI chips, nuclear and defense, with insider, congressional, contract and lobbying activity). Most of the website is free to browse. The AI connector is free for Congress data in Claude, ChatGPT, Gemini and Grok (Microsoft 365 Copilot coming soon) (congressional trades, members of Congress, bills in Congress, roll-call votes and corporate PAC donations) and for FINRA short interest and short volume, with lower usage limits. Local models and other MCP apps (Claude Code, LM Studio, Open WebUI and the like) are included in the Premium plan. The Premium plan adds every other dataset in the connectors, API keys, CSV downloads and nightly bulk files (7-day free trial). Companies are keyed by SEC CIK (a ticker is a lookup; responses carry both). Members of Congress are keyed by Bioguide id. Every row has a source link and first_seen_at (when we stored it). Raw daily prices are not available. ## License - Personal, non-commercial use only, on every plan (Basic and Premium): no republishing, redistribution, public display, resale, use for a business or client, or AI model training, of the data or anything derived from it, including API and MCP output, CSV downloads and bulk files. Rate limits and quotas are part of the Terms (https://13f.ai/terms). Commercial license: https://13f.ai/commercial - Agents: you may read and summarize this data for the person who connected you, in that person's own conversation. Do not republish it, store it in a shared database or train on it. ## Access - REST API: https://13f.ai/api/v1/ . Header `Authorization: Bearer `. Responses: `{ "data": [...], "next_cursor": string|null, "as_of": ISO time }`. Page with `cursor`, `limit` (default 100, max 1000). Dates YYYY-MM-DD, snake_case, numbers as numbers. 60 requests/minute/key (best effort). Premium plan: add `format=csv` to a list endpoint for CSV (at most 10,000 rows), and GET https://13f.ai/api/v1/bulk for the nightly gzip CSV files with short-lived signed links. - OpenAPI 3.1: https://13f.ai/api/v1/openapi.json (public, no key) - Agent sign-up: POST https://13f.ai/api/v1/agent/signup with {"email"} returns a Stripe checkout link (checkout_url) for the Premium plan, a claim_secret (shown once) and a poll_url. Give the link to the person; they pay. Then GET the poll_url with Authorization: Bearer : status is pending, paid or expired, and the first poll of a paid sign-up returns the API key once. 409 means the email already has an account (the person signs in at https://13f.ai/login). Premium starts with a 7-day free trial; the card is added at checkout. Details: https://13f.ai/developers#agents - Human docs: https://13f.ai/developers - MCP server (Streamable HTTP, stateless): https://13f.ai/api/mcp . Sign-in with OAuth 2.1 + PKCE (discovery: https://13f.ai/.well-known/oauth-protected-resource; users add the URL as a custom connector in Claude, a custom MCP server in ChatGPT or a custom app in Gemini), or a bearer API key in the Authorization header (keys are on the Premium plan). All tools read-only. Signed-in Basic accounts can use the congressional tools (get_congress_trades, get_politician_overview, get_bills, get_votes, get_pac_donations, get_campaign_finance, search_entities, list_themes) and the congressional part of get_company_overview, get_crypto_overview, get_theme and get_recent_events; other data returns a short message that it needs the Premium plan. The Basic plan covers " + assistantNames("and", undefined, { soon: false }) + " only (decided by the redirect addresses the OAuth client registered, never its name): a Basic account that signs in from any other client, such as a local model, Claude Code or Cursor, gets a 402 payment_required saying the app needs the Premium plan. Premium, trial and complimentary accounts work from any client. Basic accounts are limited to 30 requests per minute and 500 per day. ## Website pages - [Congressional trades](https://13f.ai/congress-trades): Stock trades disclosed by members of the House and Senate under the STOCK Act. - [Executive-branch trades](https://13f.ai/executive-trades): Stock trades reported by the President, Cabinet members and other senior officials of the executive branch, from OGE Form 278-T. - [Bills in Congress](https://13f.ai/bills): Bills and resolutions in the House and Senate, with each sponsor, policy area and latest action. - [Roll-call votes](https://13f.ai/roll-call-votes): How the House and Senate voted on each recorded vote, with every member's position and the bill voted on. - [Corporate PAC donations](https://13f.ai/pac-donations): Gifts from company political action committees to candidates for Congress, from FEC reports. - [Lobbying](https://13f.ai/lobbying): Who pays Washington lobbyists, how much, and on which issues. - [Capitol Hires](https://13f.ai/capitol-hires): Lobbyists whose filings say they once worked in a member of Congress' office, on a committee or in the executive branch, with the public company that hired them. - [Lobbying and contracts](https://13f.ai/lobbying-and-contracts): What each company reports spending on lobbying, next to the federal contracts it was awarded, by year, with the agencies that appear on both sides. - [Government contracts](https://13f.ai/government-contracts): Federal contracts awarded to public companies. - [Insider trades](https://13f.ai/insider-trades): Shares that executives, directors and major owners buy and sell in their own companies, from SEC Form 4. - [Planned insider sales](https://13f.ai/planned-insider-sales): Notices (SEC Form 144) that executives and other insiders file before selling shares, and whether a sale was reported afterwards. - [Executive pay](https://13f.ai/executive-pay): What public companies pay their CEO and other top executives, from the pay-versus-performance table in each proxy statement. - [Ownership stakes (13D / 13G)](https://13f.ai/ownership-stakes): Investors who own more than 5% of a company, from activists (13D) to passive holders (13G). - [Institutional holdings (13F)](https://13f.ai/institutional-holdings): What the largest funds own, from the 13F reports they file each quarter. - [Short interest](https://13f.ai/short-interest): How many shares are sold short in each stock, reported twice a month by FINRA. - [Fails to deliver](https://13f.ai/fails-to-deliver): Shares that were sold but not delivered by the settlement date, from the SEC: the largest balances by value and as a share of trading.

SEC Form 144 notices, newest first: the notice an insider or other affiliate files before selling restricted or control shares, with the person, their relationship to the company, the shares and the value the filer typed, the broker's expected sale date, whether a Rule 10b5-1 trading plan is named (has_10b5_1_plan) and the sales they report for the last three months. - get_sec_enforcement (Premium plan): SEC enforcement releases and trading suspensions. The SEC's own enforcement lists, newest first: litigation releases (the SEC's account of a court action: an allegation unless the release itself states a judgment), administrative proceedings (orders of the Commission, many of them settled) and trading suspensions (a pause in trading in one stock, usually ten business days; a pause, not a finding). - get_deals (Premium plan): Mergers, tender offers and going-private deals. Mergers, tender offers and going-private transactions grouped from SEC filings since 2015, one row per deal, latest filing first. - get_private_placements (Premium plan): Private placements (SEC Form D). Private placements from SEC Form D notices since 2015, one row per Form D or Form D/A, latest first: the issuer (name, state, entity type, industry group, ticker when it is a listed company), every issuer CIK of the offering, the exemption (06b = Rule 506(b), 06c = Rule 506(c)), the security types, the date of first sale, the total offering amount, the amount sold so far, the amount remaining, the number of investors, sales commissions and the executive officers, directors and promoters named, as filed. - get_crypto_overview (congressional part in Basic plan): Crypto overview across datasets. One-call briefing on crypto from public filings: trades in cryptocurrency (and in crypto stocks and ETFs) by members of Congress, who holds the spot bitcoin and ether ETFs among 13F filers with the quarter-over-quarter change per fund, which public companies report holding crypto (fair value, cost, year-over-year change) and the weekly CFTC positioning of leveraged funds, asset managers and dealers in CME bitcoin and ether futures, in coins. - list_themes (Basic plan): Published company themes. Lists the published themes: curated company lists such as AI chips, nuclear and uranium, defense and government stakeholders, plus lists built from our own congressional, insider and federal-contract data, each with slug, kind (curated or rule), group, one-line summary, company count and page URL. - get_theme (congressional part in Basic plan): One theme with member activity. Returns one published theme (a list of companies with something in common, chosen under a stated rule) with its membership rule, review date, change log, the case commonly made for it and the risks commonly cited, comparable ETFs and related themes. - get_recent_events (congressional part in Basic plan): What is new across datasets. A single feed of newly added data across datasets: congressional trades, open-market insider buys and sells, 13D/13G stake filings, 8-K items, lobbying filings, federal contract awards, patent grants, status changes of clinical trials sponsored by public companies and FDA first approvals and device decisions for them. - get_short_interest (Basic plan): FINRA short interest. Short interest from FINRA, published twice a month (settlement dates around the 15th and month end, about a week late): the shares investors have sold short and not yet bought back. - get_layoff_notices (Premium plan): Layoff notices (WARN Act). Mass layoff and plant closing notices that employers file with state governments under the WARN Act, newest notice first, from twelve states (CA, KY, NE, NJ, OK, OR, PA, SC, TN, UT, WA, WI). - get_clinical_trials (Premium plan): Clinical trials from ClinicalTrials.gov. Industry-sponsored clinical studies registered on ClinicalTrials.gov, with phase, overall status, conditions, interventions (names and types), enrollment and the start, primary completion and completion dates. - get_fda_actions (Premium plan): FDA drug approvals and device clearances. Decisions the FDA has made, from openFDA: approved drug submissions (Drugs@FDA), 510(k) device clearances and PMA device approvals, newest decision first. - get_h1b_applications (Premium plan): H-1B labor condition applications. H-1B, H-1B1 and E-3 labor condition applications (LCAs) that the US Department of Labor decided, newest decision first: employer, job title, SOC occupation, wage offered, prevailing wage, worksite and the number of workers asked for. - get_fha_lending (Premium plan): FHA lending by lender (HUD). Loans the Federal Housing Administration insures, from HUD's own files, as totals. - get_bank_financials (Premium plan): Bank financials from FDIC call reports. Quarterly figures from the call reports US banks file with the FDIC, summed for the banks each listed company owns: total assets and deposits, the uninsured share of deposits, commercial real estate as a share of loans and of equity, loans 30 or more days past due, nonaccrual loans and net charge-offs (total and for mortgages, commercial real estate, business loans, credit cards, auto and other consumer loans), capital ratios (common equity Tier 1, Tier 1 leverage), return on assets and net interest margin, with the change against the same quarter a year earlier. - get_card_metrics (Premium plan): Credit card metrics from SEC filings. Monthly credit card performance as issuers and card trusts report it to the SEC: the annualized net charge-off rate, the 30+ day delinquency rate (90+ where given) and loans at month end, with the change against the prior month and against a year earlier. - get_consumer_complaints (Premium plan): Consumer complaints to the CFPB. Counts of complaints filed with the CFPB about the companies it names, linked to listed companies: the complaints of the latest three complete months against the same months a year earlier, by product (credit card, mortgage, credit reporting, checking or savings, student loan and others), the biggest issues, the share answered in time and the share of closed complaints that ended with monetary or non-monetary relief, and monthly counts back to 2017. - get_executive_pay (Premium plan): Executive pay from proxy statements. What public companies pay their CEO and other top executives, from the pay-versus-performance table of each proxy statement (DEF 14A), one row per company and fiscal year: the CEO's total pay (Summary Compensation Table), the 'compensation actually paid' under the SEC's formula (it follows the share price and can be far from total pay, or negative), the average of the other named executives on both measures, and the company's and its peer group's total shareholder return (the value of $100 invested at the start of the five-year period). - get_stock_splits (Premium plan): Stock splits. Forward and reverse stock splits by the day they took effect, newest first. - get_short_volume (Basic plan): Daily short sale volume. Short sale volume, off-exchange volume and DPI for each stock on one day, from FINRA's daily files. - get_wikipedia_views (Premium plan): Wikipedia page views of company articles. How often the English Wikipedia article about each US-listed company is read, from Wikimedia's page-view data (views from people, all platforms; a day's views arrive about a day late). - get_app_ratings (Premium plan): App Store ratings of company apps. The average star rating and number of ratings of the main apps of listed companies on Apple's US App Store (about a hundred apps we chose, such as Uber, Netflix and Chipotle), one snapshot a day, and how each has changed. - get_fails_to_deliver (Premium plan): Fails to deliver (SEC). Fails to deliver from the SEC's twice-monthly files: for each settlement date, the balance of shares that brokers had failed to deliver to the buyer and not yet delivered, with the previous day's closing price. - get_merger_clearances (Premium plan): Merger clearances: FTC early terminations (HSR). Early-termination notices the FTC publishes under the Hart-Scott-Rodino Act, newest first: a notice means the parties to a reportable merger or acquisition asked to end the 30-day waiting period early and the FTC and the Department of Justice granted it. - get_financials (Premium plan): Company financials from SEC filings. A company's financial statement figures from the XBRL data of its SEC filings (mostly 10-K and 10-Q): for the latest 8 quarters and 2 fiscal years (quarters and years change that), revenue, gross profit, operating income, net income, diluted EPS (USD per share), operating cash flow, cash and equivalents, long-term debt (the noncurrent part only, not total debt) and shares outstanding, all in US dollars unless said otherwise, and the newest revenue split by business segment, geography and product (members are the company's own names, not normalised across companies, and need not add up to total revenue). - get_fund_leaderboards (Premium plan): Notable funds and fund leaderboards. The fund leaderboards from the latest quarter's 13F reports (a 13F lists a manager's long US-listed stock positions, filed up to 45 days after quarter end), and the list of about 75 notable funds. - search (Basic plan): Search 13F.ai. Search 13F.ai for a company (name or ticker), a member of Congress or a 13F fund manager, and for a company also its Congress trades, insider trades and institutional holders. - fetch (congressional part in Basic plan): Fetch a 13F.ai document. The full document for a document id: a company briefing (company:), a member of Congress (politician:), a 13F fund manager (fund:), or one dataset of a company (congress-trades:, insider-trades:, holders:). ## Tips for agents - Only have a name? Call search_entities (MCP) or GET /search?q= first to get the CIK, Bioguide id or manager CIK. - Need a readable document rather than rows? The MCP tools search (a name or a question: ranked results with id, title, url and text) and fetch (an id from search: one document with source links) cover a company, a member of Congress, a fund manager and a company's Congress trades, insider trades and 13F holders. They obey the same plans as the other tools. - To follow what is new, poll /events (or get_recent_events) with updated_since = the largest first_seen_at you have seen. - Congressional trade amounts are disclosed brackets (amount_min..amount_max), not exact figures; disclosures lag trades by up to ~45 days. - Senate trades (chamber=senate) come from an independent public mirror of the Senate's electronic reports, because the Senate's site blocks automated access: reports filed since 2014, no paper filings, a small share of lines missing, amendments not marked. source_url is always the official report; the source field says where we read it. - Crypto: GET /congress-trades?asset_type=crypto lists trades in cryptocurrency itself (House type CT, Senate 'Cryptocurrency'); trades in crypto stocks and ETFs are ordinary listed-security rows (filter by ticker). get_crypto_overview (MCP) briefs Congress crypto trades, spot ETF 13F holders, company crypto treasuries and CFTC futures positioning in one call. - IPO pipeline: GET /ipos (or get_ipo_filings) lists S-1 / F-1 registrations by status (filed, amended, priced, withdrawn). Pass ipo=true to leave out resale registrations and follow-ons by listed companies, spac=false to leave out blank-check companies. offering_amount_usd is the maximum the company registered in the SEC filing-fee table (a ceiling, often a round placeholder, not the amount raised) and is only available for filings since mid-2025; amount_raised_usd is price times shares from the final prospectus (424B4), null until the offering is priced; proposed_ticker is what the prospectus says it will list under. - Deals: GET /deals (or get_deals) lists mergers, tender offers and going-private transactions grouped from SEC filings (SC TO, SC 14D9, SC 13E3, S-4, F-4, PREM14A, DEFM14A, 425). Grouping is by rule (same SEC file number, else the same two companies, else one company's only open deal); a filing that fits two deals is left alone (ambiguous_filings). There is no offer price or terms, and nothing says whether a deal closed: stage is only the furthest form seen. Company buybacks (deal_type issuer_tender) are left out of get_deals unless include_buybacks is true. - Private placements: GET /form-d (or get_private_placements) lists SEC Form D notices. Amounts are what the issuer typed and are not checked by the SEC; an amendment's total_sold replaces the filing before it (same file_number), so never add them up. Pooled investment funds are about two thirds of filings: pass pooled_funds=false for operating companies. On /ipos, raised_before_ipo_usd adds up the Form D amounts sold before the registration (matched by CIK; not IPO proceeds). - Short selling: get_short_interest is FINRA short interest, positions still open, published twice a month about a week late (rank by shares short, days to cover or change, or pass a ticker for its history). get_short_volume is one day's short sales from FINRA's daily files, which cover off-exchange trades only; a share of 40% to 60% is ordinary and is not short interest. Do not mix the two. - Fails to deliver: get_fails_to_deliver (GET /fails-to-deliver) is the SEC's balance of shares brokers had failed to deliver on each settlement date, with the previous close. It is a CUMULATIVE balance, not that day's new fails, and the SEC says it is not evidence of abusive or 'naked' short selling. The newest settlement date is usually two to six weeks old. It is not short interest and not short volume. - Attention: get_wikipedia_views ranks company Wikipedia articles by views against their own 90-day average; get_app_ratings tracks App Store ratings of the main apps of listed companies (history from 2026-10-23). Attention for any reason is not a signal about a company's results. - Funds: get_fund_leaderboards returns the fund boards from the latest 13F quarter (notable funds, most owned, top buys and sells, biggest changes, largest, concentrated and fastest-growing managers, estimated performance). Estimated returns, turnover and copy returns are estimates from quarter-end 13F holdings, not what an investor earned. - Fund 13F changes: get_fund_filing_changes (one manager, newest report or a given quarter) returns what its 13F changed against the previous quarter: counts of new, added, trimmed and exited common-share positions, the 10 largest of each by estimated dollars, puts and calls apart, and ai_summary, two to four sentences written by an AI from those changes alone and checked against them (null when none exists). Estimated dollars are shares changed times the later price per share in the filings; a change in shares is not always a decision (index tracking, splits and mergers move positions too). - Company financials: GET /companies/{ticker_or_cik}/financials (or get_financials) gives a company's revenue, gross profit, operating income, net income, diluted EPS, operating cash flow, cash, long-term debt and shares for the latest 8 quarters and 2 fiscal years, with the newest revenue split by segment, geography and product, from the XBRL data of SEC filings (mostly 10-K and 10-Q; check form_type, some annual figures come from a proxy statement). Every figure has its form, accession number and filing link; periods carry fiscal_year and fiscal_quarter. Quarters are calendar-aligned frames (CY2025Q3); a fourth quarter's revenue, gross profit, operating income and net income are derived as the year minus the first three quarters and flagged derived: true (derived_from names the filings, only from a 10-K year and 10-Q quarters; EPS is never derived); operating cash flow exists for first quarters and years only; long_term_debt is the noncurrent part, not total debt; banks and insurers often lack revenue, gross profit, operating income and debt concepts; the revenue split period_end is month-end rounded and can lag one quarter. - Layoffs, executive pay and splits: get_layoff_notices, get_executive_pay and get_stock_splits run the same queries as the pages and REST endpoints below, with the same default windows. - Layoff notices: GET /layoffs lists state WARN Act notices (12 states). Only about one in ten is matched to a public company (cik, ticker); pass listed=true to keep those. New Jersey and Pennsylvania publish no notice date. - Merger clearances: get_merger_clearances (GET /merger-clearances) lists FTC early-termination notices under the Hart-Scott-Rodino Act. Coverage is partial by design: only granted requests, none from 2021-02-04 to 2025-02-10, and not every deal. acquiring_match / acquired_match is 'possible' for a loose name match that can be wrong. - Clinical trials: GET /clinical-trials (or get_clinical_trials) lists industry-sponsored studies from ClinicalTrials.gov. view=completed_phase3, updates, status_changes (changes we observed since we first stored each study, not the registry's history) or upcoming (soonest primary completion). cik and ticker are set only for a confident sponsor match, so a null ticker does not mean a private sponsor. A completed study is not a result, and registry dates are the sponsor's own. - FDA decisions: GET /fda-approvals (or get_fda_actions) lists drug approvals (Drugs@FDA), 510(k) clearances and PMA approvals from openFDA, newest decision first; new_drugs=true keeps first approvals of NDAs and BLAs. It is a record of decisions made, not a calendar of coming ones (no PDUFA dates). Not endorsed by the FDA; not for medical decisions. - H-1B labor applications: GET /h1b (or get_h1b_applications) lists labor condition applications that the Department of Labor decided, newest decision first, with the employer, job title, wage offered and number of workers; the page ranks the top filers. An application is not a hire, a petition or a visa, and one can cover several workers. - FHA lending (HUD): GET /fha-lending (or get_fha_lending) gives FHA-insured loans by lender and month as totals: home loans (dataset forward), reverse mortgages (reverse) and apartment, senior-housing and care-home loans (multifamily), for a company (ticker or cik) or a lender name. A lender's share is its share of FHA loans, not of all mortgages; HUD names the current holder and servicer of an apartment loan, not the lender that made it; a joint venture is shown once and never added to its owners. Totals only: no borrowers. Each answer carries the HUD page as source_url and cite. - Executive pay: GET /executive-pay gives each company's CEO total pay and 'compensation actually paid', the other named executives' averages and shareholder return per fiscal year, from proxy statements; latest=true keeps each company's most recent year. Only companies with a single CEO in the year have CEO figures; amount_to_check flags amounts over $1 billion. - Bank financials: GET /bank-financials (or get_bank_financials) gives quarterly FDIC call report figures for the US banks a listed company owns: total assets and deposits, the uninsured share of deposits, commercial real estate as a share of loans, loans past due, nonaccrual loans and net charge-offs (total and by loan type), capital ratios and return on assets, with the change against a year earlier. Name a company (ticker, cik or a name) for its quarters, or name none and pass metric (and quarter) to rank the listed companies. The figures are for the company's US bank subsidiaries, not the consolidated holding company. Each row has source_url and cite. - Credit card metrics: GET /card-metrics (or get_card_metrics) gives monthly credit card performance from SEC filings: the annualized net charge-off rate, the 30+ day delinquency rate and loans at month end, with the change against the prior month and a year earlier. Issuer-wide series (issuer_wide) come from the issuer's own 8-K (Capital One, Synchrony, American Express, Bread Financial, Discover to April 2025); securitized card pools (securitized_card_pools) come from card trusts' 10-D reports and add yield, excess spread and payment rate. The two kinds are different sets of loans: never add them or call a pool the issuer's whole book. Each issuer defines its terms its own way (definition on each series). Name a company (ticker or cik) or series keys, or none for all; months goes back to 2019. Each series and month has source_url and cite. - Consumer complaints: GET /consumer-complaints (or get_consumer_complaints) gives counts of complaints filed with the CFPB about the companies linked to listed companies: the latest three complete months against a year earlier, by product, the biggest issues, the share answered in time and the share of closed complaints that ended with relief, and monthly counts back to 2017. Name a company (ticker, cik or a name) for its figures, or name none and pass sort and product to rank the listed companies. Complaints are unverified and grow with a company's customer count, so compare trends, not totals. No complaint text is stored. Each row has source_url and cite. - Lender stress: the page /lender-stress (and /lender-stress/) puts three existing datasets side by side for each listed consumer lender: card and auto loan past-due and charge-off rates of its US bank subsidiaries (FDIC call reports, quarterly), monthly card charge-offs and 30+ day late payments (SEC filings; securitized card pools listed apart and never added to the issuer), and CFPB complaints (the latest three months against a year earlier, as on /consumer-complaints). Each figure keeps its own source and date; there is no combined score. For the data itself use get_bank_financials, get_card_metrics and get_consumer_complaints. - Stock splits: GET /stock-splits lists forward and reverse splits that have taken effect; ratio reads -for- (1-for-10 is a reverse split). Stock dividends are left out. - Votes: get_votes (recorded House and Senate votes since 2015, by member, bill, chamber, words and dates; with a member it also gives that member's position, yea, nay, present or not voting) is free for every signed-in account; the REST equivalents are GET /roll-call-votes and GET /roll-call-vote-positions (Premium plan). Voice votes and unanimous consent are not recorded by name, so a bill can pass without a row; a vote on an amendment or a rule is not a vote on the bill. Senate votes come from Voteview (UCLA) a few days after the vote, without a time of day, and leave out the Vice President's tie-breaking vote. - Bills and PAC money: get_bills (bills and resolutions in Congress, by sponsor, policy area, title words, Congress and dates) and get_pac_donations (gifts from company PACs to candidates for Congress, by company, recipient, cycle, dates and minimum amount) are free for every signed-in account; the REST equivalents are GET /bills and GET /pac-donations (Premium plan). A gift to a campaign is not a vote and says nothing about intent. - FINRA short selling: get_short_interest (short interest, twice a month) and get_short_volume (daily short sale volume and DPI) are free for every signed-in account; the REST equivalents are GET /short-interest and GET /short-volume (Premium plan). Source: FINRA; no advertising next to this data. Short volume is one day's short sales, not open positions. - FINRA short selling: get_short_interest (short interest, twice a month) and get_short_volume (daily short sale volume and DPI) are free for every signed-in account; the REST equivalents are GET /short-interest and GET /short-volume (Premium plan). Source: FINRA; no advertising next to this data. Short volume is one day's short sales, not open positions. - Executive branch: get_exec_trades (GET /exec-trades) lists stock trades of the President, the Vice President, Cabinet members, other Senate-confirmed officials and White House staff from OGE Form 278-T, newest first. Free for every signed-in account; public records that may be used for dissemination to the public (5 U.S.C. 13107(c)), so no advertising. The form has no ticker column: asset_description is the asset as printed and cik is set only when it matched a listed company. Amounts are brackets. read_from_scan_by_model true means a scanned report (the President's) read by a model; check the linked report. - Lobbying and contracts: get_lobbying_and_contracts (page /lobbying-and-contracts) gives, per company and calendar year, the reported lobbying spend next to the federal contract awards, the corporate PAC gifts and the agencies on both sides; for one company it links the lobbying reports (lda.senate.gov) and the largest awards (usaspending.gov). Each report and award is counted once. Lobbying and contract awards are reported separately; showing them together does not mean one caused the other. Same plan as lobbying and contracts. - Capitol Hires: get_lobbying with former_government_staff true (or member_bioguide_id) lists lobbyists whose filings say they once worked in a member of Congress' office, on a committee or in the executive branch, with the lobbying firm and a link to the filing. Same plan as lobbying. Each row reflects what was disclosed at the time of filing, and a lobbyist listed may no longer be registered. A member is linked only when exactly one fits; otherwise member_name is the text as written. - Net worth: get_politician_net_worth (estimated net worth of a House member from the annual financial disclosure, as a low, middle and high figure per report year, with a link to each report; House only, brackets not exact values) is free for every signed-in account; the REST equivalent is GET /politician-net-worth. - Campaign money: get_campaign_finance (what a member of Congress or other candidate raised and spent per election cycle, with cash on hand, debts and the split of receipts into individuals, PACs and party committees, from the FEC's candidate summaries; totals only, no individual donor is named) is free for every signed-in account, and get_politician_overview carries the latest two cycles; the REST equivalent is GET /campaign-finance (Premium plan). - Insider trades: transaction_code P = open-market purchase, S = open-market sale; other codes are grants, option exercises, tax withholding, gifts. - Planned insider sales: GET /planned-insider-sales (or get_planned_insider_sales) lists SEC Form 144 notices, which an insider files before selling shares. A notice is a plan, not a sale; shares_to_sell and aggregate_market_value are as the filer typed them. form4_* fields and days_to_form4 link a notice to the first Form 4 that reports a sale by the same person within 90 days (null when none is on file, which does not mean no sale). has_10b5_1_plan means the notice gives a trading-plan adoption date. - SEC enforcement: GET /sec-enforcement (or get_sec_enforcement) lists the SEC's litigation releases, administrative proceedings and trading suspensions. A litigation release is the SEC's account of its allegations unless it states a judgment; a suspension is a pause in trading, not a finding. The lists give names and a release number, not a summary: read the release at url. Names are matched to companies automatically; match_tier confident is a same or very close name, possible may be a different company, so never state that a company was charged on a possible match. - Some large endpoints require a ticker, cik or date window; the 400 error says which.
