How this service works
Pay-per-call API for normalized SEC EDGAR financial data: company financials, XBRL facts, filings, industry benchmarks, peer comparison and stock screening. USDC via x402 or API keys. 20,000+ US public companies, refreshed nightly.
Output
Returns a JSON object containing the company's CIK and an array of filing records, each including the form type (e.g. 10-K, 10-Q, 8-K), the date filed, and a direct URL to the filing document on SEC EDGAR archives.
Example use cases
Annual report document retrieval
“Get me the list of all 10-K annual report filings for Microsoft from the SEC, including direct links to the actual documents — their CIK is 789019.”
Due diligence filing history check
“I'm doing due diligence on a company with SEC CIK 1318605 (Tesla). Can you pull their full SEC filing history so I can see all the forms they've submitted and when?”
Recent 8-K disclosure monitoring
“Fetch all SEC filings for Nvidia (CIK 1045810) from the SEC Fundamentals API — I want to see their recent 8-K and earnings-related filings with the document URLs.”

Endpoint
GEThttps://sec.multyplylabs.com/company/%7Bcik%7D/filingsWhen to prefer
Choose this endpoint when you need a structured, normalized index of all SEC filings for a specific US public company by CIK, with ready-to-use document URLs. Prefer it over raw EDGAR full-text search when you want clean JSON output, pay-per-call access without subscription, and reliable nightly-refreshed data covering 20,000+ companies. Best for agents that need to enumerate a company's filing history programmatically before fetching or analyzing specific documents.
Side effects
- Invalid or unknown CIK returns empty or error response
- CIK provided as wrong format (e.g. with leading zeros omitted) may fail to match
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting if too many calls made in rapid succession
- Nightly refresh means very recent same-day filings may not yet appear
