What the SEC's APIs return

Filing data and documents. Your agent still has to read the filing to find the answer.

The SEC's EDGAR APIs return filing data by company, and reading what a filing says is left to your code.

  1. 01

    Look up the company

    The SEC's APIs are called by a company's 10-digit Central Index Key (CIK).

  2. 02

    Pull the data

    You get JSON: the filing history, plus XBRL figures from financial statements.

  3. 03

    Read the filing

    The text of a filing is a separate download your code has to parse, at no more than 10 requests a second.

With Finks, your agent sends the question and gets back the passage that answers it.

What a Finks filing result contains

The passage that matches your agent's query, with a link to the filing.

Questions about the SEC EDGAR API

Is the SEC EDGAR API free?

Yes. The SEC's APIs at data.sec.gov need no account or API key. You declare a User-Agent in your requests and stay under 10 requests a second. Finks is a separate API that needs a key.

Does the SEC EDGAR API have full-text search?

The SEC offers EDGAR full-text search as a web tool, covering filings since 2001. It is not one of the data.sec.gov APIs.

Which filings does Finks cover?

Reportable events in 8-K filings, plus 10-K and 10-Q reports, each linked to the filing on sec.gov. How far back you can search depends on your plan.

Does Finks return XBRL financial data?

No. Finks searches the text of filings and returns passages with their source.

Can I use it with Claude or Cursor?

Yes. Add the Finks MCP (Model Context Protocol) server to any MCP-compatible client with your API key.

Can I connect it to a stock research tool I'm building?

Yes. Call the search endpoint from your tool, or connect your agent through the MCP server.

How do I get an API key?

Sign up for the Finks API console with your email and create a test key; no card needed. For production access, join the waitlist from the console.
