Guides

Build with the API

Task-focused guides that get you from auth to working code. Call the REST API directly, or connect an AI agent over MCP — same SEC data, your choice of interface.

Tutorials

Learning-oriented. Follow these start to finish.

Quickstart

Zero to a real SEC response in about five minutes. Resolve a company name to its CIK, then pull its 13F holdings — two curl calls.

How-to guides

Task-oriented. Each one solves a specific problem.

Using the REST API

One Bearer token, one JSON shape across every source. Auth, endpoints, errors, and rate limits in curl, Python, JavaScript, and Go.

Using the MCP tools

Connect an AI agent over the Model Context Protocol and pull SEC EDGAR data as typed tool calls. No REST client, no parsing.

Explanation

Understanding-oriented. The why behind the design.

Why unified public APIs

The data is free and public domain. What you pay for is the normalization — one interface over four sources that each speak a different dialect.
