SEC Filing Monitor API

Monitors SEC EDGAR for new filings by company (ticker or CIK), form type (8-K, 10-K, 10-Q, Form 4, S-1, 13F...), or full-text phrase, and returns each filing exactly once as one clean JSON record. Built on the SEC's official public APIs: no API key, no login, no scraping fragility. Runs on Apify: schedule it, wire an alert, or let an AI agent call it as an MCP tool.

Run it on Apify Setup guide vs. sec-api.io

Limits, stated plainly

The data source is the SEC's own free API. You could call EDGAR yourself; what you pay for is the managed monitor: delivery state, cursors, ticker resolution, pagination, rate-limit etiquette, and one stable schema over EDGAR's two differently-shaped APIs.
Metadata and links, not filing bodies. It tells you a filing exists and links to it; it does not parse financial statements or XBRL.
Watchlist depth is EDGAR's recent window (~1,000 filings per company); full-text search covers 2001 onward.
Filers without a listed ticker (funds, insiders) are watched by CIK.
