EDGAR filings since 1993, full-text search and parsed forms

About
sec-api.io indexes SEC EDGAR: more than 20 million filings from 1993 on, including filers that no longer exist, with full-text search across filing bodies and exhibits. It also parses the forms into structured data, among them financial statements, Form 3, 4 and 5 insider trades, 13F holdings, 8-K items, audit reports and fees, executive compensation, Form ADV adviser filings, offerings and SEC enforcement actions.
Reach for it when a question goes past the filings Marvin Labs holds for a company: a phrase searched across every filer, a delisted issuer, or a form such as an adviser registration.
The free plan is 100 API calls in total, not per month. Personal & Startups, $49 a month, is for individuals and teams under five; using the data inside a firm takes Business Internal Use at $199. Every plan includes the MCP server. Click Add and paste the key from your sec-api.io account page. It travels in the connection URL, the only method sec-api.io documents, and is encrypted before it is stored.

Frequently asked questions
- What is a Connector?
- A Connector is a remote MCP server that a third party runs and Marvin Labs knows how to reach. Marvin Labs supplies the endpoint and the setup; you bring your own sec-api.io account. Once added, AI Analyst Chat and Deep Research Agents call its tools when a question needs them, and the answer shows which tool was called and what it returned.
- Does the sec-api.io Connector require authentication?
- Yes. sec-api.io needs an API key from your account, which you paste when adding the Connector. It is encrypted before it is stored and never shown again.
- Does sec-api.io change how financial data is sourced?
- No. When a question can be answered from the filings, earnings calls, and press releases Marvin Labs ingests through Automated Data Import, it answers from those. sec-api.io is used only when a question needs data those documents do not carry, and the answer attributes that output to it.
- Where is sec-api.io available?
- In both AI Analyst Chat and Deep Research Agents. Its tools stay out of the model's context until a request needs one, so an unused Connector takes up no context window.
