FAQ
Why not EDGAR itself, or OpenInsider?
EDGAR is the source and it is free, but each Form 4 is an XML file inside a filing folder, and the feeds list filings, not trades. Insidewell parses every new Form 4 about once a minute into flat JSON rows you can filter. OpenInsider is a free website with screens, not an API with keys, uptime and an MCP server.
Why not sec-api.io, Financial Modeling Prep or EODHD?
They are broad financial-data suites: sec-api.io Personal is $55 a month ($49 billed yearly), FMP includes insider trades from its $19/month (yearly) Starter plan, EODHD from its $59.99/month Equity Analyst plan (their pricing pages, 30 Sep 2026). If insider trades are what you need, Insidewell does that one job with cluster buys built in: 100 free calls a day, $5 pay-as-you-go, or $19/month.
How fresh is it?
The ledger reads EDGAR's latest-filings feed about once a minute and each day's full form index as a completeness check. Every response has data.updated (the last time new filings were added). Insiders must file within 2 business days of a trade, so the trade date is usually 0-2 days before the filed date.
Why does the same purchase appear more than once?
Because more than one person filed it: a fund and the director who controls it each file their own Form 4 for the same shares, and a filing can list several funds with separate rows (ownership_nature says which). /api/trades shows every row as filed; cluster buys count an identical trade reported by several filers once and list the others under also_reported_by.
What do the codes mean?
P = open-market or private purchase, S = open-market or private sale (the two most investors watch). Others: A grant or award, M option exercise, F shares withheld for tax, G gift, D disposition to the issuer, and more (transaction_type spells each one out).
What is a cluster buy?
Two or more different insiders of the same company buying its stock on the open market within 7 days of each other (you can change the window and the minimum number of insiders). Many investors watch these more closely than a single buy; it is information, not a recommendation.
Is there a key or a cost?
The free tier needs no key: 100 calls a day per IP. Paid keys: Watchlist $19/month for 10,000 calls, Desk $49/month for 50,000 calls, Fund $99/month for 150,000 calls; or pay as you go: $5 for 2,000 calls that never expire. Yearly billing gives 2 months free. Every call returns up to 100 trades or clusters. Send the key as the x-api-key header. No surprise overage charges; cancel any time.
Can I use it from Claude, Cursor or another AI agent?
Yes. Add the MCP server URL below (with your key as a Bearer token for paid limits). Tools: insider_trades, cluster_buys and data_status.
Is this investment advice?
No. Insidewell reports what insiders filed with the SEC, as filed. It is information only, not investment, legal or tax advice, and not a recommendation to buy or sell any security. Check the linked filing before relying on any row.
Where does the data come from?
SEC EDGAR: the latest-filings feed and the daily form index, and each Form 4 / 4/A filing itself (US government data, public domain), read with a descriptive User-Agent within SEC fair-access limits. Not affiliated with or endorsed by the SEC.
