Tools 40 found in our last check

• get_transactions

  Search SEC Form 4 insider transactions with rich filters: ticker, insider CIK, transaction code/category, date range, a dollar floor (min_value), institutional-ownership trend, and (Pro+) upper trade-size bounds plus post-trade return screening (1d/1w/1m/3m/6m, returns as fracti…

• get_recent_filings

  Live feed of the newest SEC Form 4 filings, sorted most-recent-first, optionally filtered to one ticker. New filings typically appear within ~60 seconds of SEC publication. Use this to check "what just happened" rather than get_transactions (built for filtered/historical search…

• get_filing

  Fetch one Form 4 filing by its exact SEC accession number (format NNNNNNNNNN-YY-NNNNNN, e.g. 0000320193-26-000001). Use this once you already have an accession number from get_recent_filings or get_transactions. Returns filed/period-of-report dates, company and insider identity,…

• get_insider_profile

  Identity card for one insider by CIK (SEC's numeric filer identifier): name, all known titles, and director/officer/10%-owner role flags. Returns NO transactions — when the user asks what an insider bought, sold or filed, use get_insider_transactions (raw rows) or get_insider_ca…

• get_insider_transactions

  All Form 4 transactions filed by one insider (by CIK), filterable by ticker, transaction code, date range, and 10b5-1 exclusion. Use this once you have an insider's CIK on hand; get_transactions with insider_cik= gives the same rows alongside its broader filter set, while get_in…

• get_company_overview

  Company profile for a single ticker — name, CIK, SIC sector/description, state of incorporation, website, total Form 4 filing count, and active insider count. Use this for company identity/metadata; use get_company_insiders to list who is filing, or get_transactions with ticker=…

• get_company_insiders

  Full roster of insiders who have ever filed a Form 4 for a given ticker — name, CIK, titles, director/officer/10%-owner flags, last-filed date, and total transaction count per insider. Use this to enumerate a company's insiders (e.g. before pulling each one's career summary); us…

• get_signals

  Cluster buy/sell signals — multiple insiders at the same company trading in the same direction within a short window, a stronger conviction signal than any single trade. Excludes 10b5-1 plan trades automatically by construction. Returns signal type, detection date, buyer/seller…

• get_form144

  Form 144 notice-of-proposed-sale filings — insiders disclose intent to sell roughly 2 days before the matching Form 4 sale lands, so this is an early-warning signal, especially discretionary (non-10b5-1) notices. Filter by ticker, insider name (partial match), date range, or exc…

• get_holdings

  Institutional 13F-HR positions — filter by ticker (CUSIP resolved to ticker automatically), CUSIP, manager CIK, quarter, or minimum position value. Answers "who owns NVDA" or "which managers hold AAPL this quarter"; pair with get_managers to look up a manager's identity/AUM, or…

• get_managers

  Browse the institutional manager index — each manager with their latest 13F-HR filing date and AUM. Filter by name (partial match — "Berkshire" returns Berkshire Hathaway) or minimum AUM. Pair with get_holdings to see what a given manager owns. Requires Business plan. Paginated,…

• get_sentiment

  Monthly insider-sentiment score for a ticker (MSPR-style, -100 to +100; positive = net buying conviction), one point per month, defaulting to roughly the last 12 months. Automatically excludes 10b5-1 plan trades so the score reflects discretionary conviction, not pre-scheduled d…

• get_insider_career_summary

  Aggregate career rollup for one insider by CIK — first/last transaction dates, total shares/value bought vs sold, top companies traded, transaction-code breakdown, 10b5-1 plan split, and median post-trade returns (stored as fractions, e.g. 0.05 = +5%). Use this instead of get_in…

• check_usage

  Snapshot of the authenticated API key's current usage — plan name, requests made today, daily limit, and all-time request count. Use this for a quick right-now check; use the generated get_usage_history tool for a daily trend over time, or get_key_activity for a per-request log.…

• verify_setup

  Diagnostic check: confirms FORM4API_KEY is present and valid, the backend is reachable, and reports your current plan — returns a pass/fail/warn per check plus concrete next steps (where to get a key, how to upgrade) instead of a raw error. Run this first whenever another tool f…

• search

  Resolve free-text input — a company name, ticker fragment, or a person's name — to a ticker or CIK. This is usually the right FIRST call when a user names a company or insider you don't already have an identifier for; feed the resulting ticker into get_company_overview/get_trans…

• research_company

  Bundled insider-research context for one ticker in a single call — company profile, recent insider transactions (10b5-1 flagged), cluster buy/sell signals, monthly sentiment score, and a computed net buy/sell direction summary. Use this FIRST for any company insider-research que…

• explain_signal

  Explain why a signal fired: the insiders and trades counted, what was excluded, and the criteria (Business plan+). Use this when the question is WHY a named company's signal fired, or WHICH insiders and trades made up its cluster. It takes the ticker directly, so there is no nee…

• get_company_peers

  Peer companies in the same SIC industry, ranked by recent Form 4 activity. Returns other tracked companies in the same industry as the given ticker, for "similar companies" links. Candidates share the company's 4-digit SIC code (matchLevel "sic4"); when too few of those have For…

• get_company_returns_summary

  What happened after insiders traded at a company (Pro plan+). Summarises price returns after insider open-market trades at one company, for buys and for discretionary sells, next to a site-wide baseline computed the same way. The unit is an event: one per company per filing date…

  Get one politician's congressional trading profile (Pro plan+). Returns one politician's profile — identity fields, total/buy/sell trade counts, most recent trade's disclosure date, their top N most-traded tickers (by trade count), and their N most recent trades (same shape as G…

• get_congress_ticker_rollup

  Which politicians traded a ticker, with net buy/sell counts (Pro plan+). Returns every politician who has a non-superseded congressional trade in the given ticker, each with their trade/buy/sell counts, plus ticker-level totals. Optional window_days restricts to trades with a tr…

  Browse insiders alphabetically by surname. Returns the A-Z rail with a count per letter, plus one page of insiders under the requested letter. Omit `letter` to get the rail and totals with no rows. Names come from EDGAR surname-first ("HENNEMAN JOHN B III"), so alphabetical orde…

• get_insider_leaderboard

  Ranked leaderboard of insiders by buy track-record (Business plan+). Returns the top insiders ranked by historical buy performance — same scored-buy methodology as GET /v1/insiders/{cik}/scorecard, applied across the whole corpus rather than one insider. Use this to discover whi…

• get_insider_scorecard

  Get insider buy track-record scorecard (Pro plan+). Returns the historical hit rate and average/median return of an insider's discretionary open-market buys (TransactionCode=P, excluding 10b5-1 plans and derivatives), plus their best and worst scored buy. Scores use absolute ret…

  Recent, per-request API activity log for the authenticated key. Returns the most recent HTTP requests made with the authenticated API key, most recent first, including the endpoint path, response status code, duration in milliseconds, and timestamp. Use this to debug integration…

• get_status_history

  Measured uptime history for the public status page — trailing 90-day daily breakdown. Returns a daily breakdown of measured API uptime over a trailing 90-day window, computed from an internal heartbeat probe that runs every 5 minutes and performs the same DB-connectivity check a…

• get_usage_history

  Daily request counts for the authenticated key over a trailing window. Returns a daily time series of request counts for the authenticated API key over the trailing N days — one data point per calendar day (UTC). Use this to plot usage trends or check rate-limit headroom over ti…

• get_webhook_events

  Replay webhook delivery events since a given timestamp (default: last 24h). Returns up to 500 delivery attempts across all of the authenticated key's subscriptions since `since` (default: last 24 hours), most recent first — delivery id, subscription id, event type, attempt count…

• health_ingestion

  Ingestion-death detector — Form 4 freshness, parse-queue health, price-feed freshness. Returns live (uncached) ingestion health: Form 4 processing freshness (stale after 90 minutes during the weekday 06:00-22:00 US Eastern EDGAR activity window, counted from the later of the las…

• list_companies

  List companies with a public ticker, sorted by name or total filings. Returns a single page of companies that have a tracked public ticker — for browsing or building a company picker, not for searching by name or CIK (there is no full-text search here; use GET /v1/companies/{tic…

• list_congress_politicians

  Ranked rollup of politicians by congressional trade activity (Pro plan+). Returns a paginated list of politicians who have at least one non-superseded congressional trade, each with total/buy/sell counts (sells include both Sale and PartialSale; Exchange trades count only toward…
