The Securities and Exchange Commission’s filings database. Every public company in the US files here, every filing is timestamped and immutable, and every disclosure (revenue, debt, risk factors, executive compensation, M&A activity, insider trading) is structured for machine retrieval. Free and authoritative.

Why this matters for AI agents

If your agent is answering anything about a US public company — financials, legal exposure, IP, executive turnover, recent material events — the answer is in EDGAR. The data is structured (XBRL), so you don’t have to parse PDFs.

The two key flows:

1. Filings flow. “Show me Apple’s recent 10-Q.” → edgar_ticker_to_cik("AAPL") → edgar_company_filings(cik) → list of filings with accession numbers, form types, filing dates.

2. Concepts flow. “What was Apple’s revenue trend the last 4 quarters?” → edgar_company_concept(cik, "Revenues") → time series of XBRL-tagged values across periods.

3. Peer/competitor flow. “Who competes with Apple?” → edgar_companies_by_sic({ticker_or_cik: "AAPL"}) → resolves Apple’s own SIC code (3571, Electronic Computers) and returns other SEC filers under that code, listed-ticker peers first. Pass a sic code directly instead of a company to browse an industry cold.

4. Entity-resolution flow (parent ↔ subsidiary). sponsor_to_filer({sponsor: "Merck Sharp and Dohme"}) resolves a subsidiary/operating name up to its listed parent (MRK). filer_to_sponsors({ticker_or_cik: "MRK"}) goes the other way — the parent’s full disclosed subsidiary list from Exhibit 21 of its latest 10-K, with jurisdiction and filing provenance. Pass name_filter to check one candidate name without reading the whole list.

5. Product-level revenue. “How much revenue did Keytruda generate?” → edgar_product_revenue({ticker_or_cik: "MRK", product_filter: "Keytruda"}). edgar_company_concept/edgar_company_facts only expose undimensioned XBRL totals — a product/segment breakdown is tagged with an XBRL dimension (a “Keytruda [Member]”), invisible to those APIs. This reads SEC’s own rendered Financial Report of that dimensional data straight out of the 10-K’s revenue-disaggregation note, with a citation (accession, filing date, report URL).

Both flows are usually preceded by edgar_ticker_to_cik or resolve_entity({type: "company", value: "AAPL"}) to get the canonical 10-digit CIK.

Auth

None. SEC EDGAR is a free, public, no-auth service. Pipeworx forwards a polite User-Agent header to comply with SEC’s API guidelines.

Citable URIs

pipeworx://edgar/company/{cik}/filings
pipeworx://edgar/company/{cik}/facts

Embed in your output. Stable across reorganizations — companies rebrand, but their CIK doesn’t change.

Form types worth knowing

For insider trades specifically, see the dedicated insider-trading pack — it surfaces Form 4 / 13D / 13G changes with cleaner schemas.

Common pitfalls

• Concept name drift. SEC filers occasionally change the XBRL concept they tag for revenue. The default Revenues concept may be stale for newer fiscal years; try RevenueFromContractWithCustomerExcludingAssessedTax as a fallback.
• Period mismatches. Fiscal years end at different times across companies (Apple = Sept, Microsoft = June, Google = Dec). When comparing, always disclose the period.
• CIK formatting. Some endpoints want zero-padded 10-digit (0000320193), some want unpadded (320193). Pipeworx accepts either; the cik_padded field in edgar_ticker_to_cik is the canonical form for resource URIs.
• Real-time-ish, not real-time. Filings appear on EDGAR within minutes of submission, but Pipeworx caches results. For breaking-news-grade timeliness, set Cache-Control: no-cache (anonymous limit applies) or check the _meta.cache.fresh_until field.
• Concept availability differs. Smaller filers tag fewer XBRL concepts than large ones. edgar_company_concept may return empty arrays for valid concepts that the company simply doesn’t report. Use edgar_company_facts to see which concepts a company DOES report.
