Source-backed SEC / EDGAR API

SEC filings as clean, source-linked JSON.

SEC filings are public. SourceKeel structures them into JSON and links every value back to the filing it came from. Commercial use and redistribution are allowed on paid plans.

Details

How it works in practice.

Provenance on every value

Not just a link to the filing. You get the accession, document, table, and XBRL tag behind each number.

Redistribution is included

Some SEC APIs need a sales call before you can display or resell data. Ship and Mirror include it.

Precomputed, not live

Responses come from precomputed objects, not live parsing, so the API stays fast under load.

Mirror the dataset

Weekend bulk snapshots and daily delta windows into your warehouse. Local copies are allowed on Mirror.

Agents

Use it from an agent.

The CLI doubles as an MCP server over stdio. Same key, same source-backed objects, no private backend path.
