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
A JSON object containing the company's CIK, a count of total facts, and an array of normalized financial fact objects each with a concept name (e.g. 'revenue'), numeric value, and fiscal year — drawn from the company's XBRL filings on SEC EDGAR, refreshed nightly across 20,000+ US public companies.
Example use cases
Deep-dive company financial history
“Get me all the SEC XBRL financial facts for Tesla — CIK 1318605 — I want to see every metric they've ever reported to the SEC across all fiscal years.”
Fundamental data pipeline for quant model
“Fetch all normalized XBRL facts from SEC EDGAR for Microsoft, CIK 789019, and load them into my financial model so I can compute custom ratios.”
Verify reported revenue figures
“I need to double-check Amazon's revenue figures as reported to the SEC — can you pull all their XBRL financial facts using CIK 1018724?”
Technical details
Endpoint
GEThttps://sec.multyplylabs.com/company/%7Bcik%7D/factsWhen to prefer
Choose this endpoint when you need the full universe of normalized XBRL financial concepts for a single US public company identified by CIK — ideal for building financial models, populating databases, or doing comprehensive fundamental analysis. Prefer it over the income-statement endpoint when you need raw, granular XBRL concepts rather than structured annual statements, and over the screener endpoint when you already know the specific company and want all its data rather than filtering across peers.
Side effects
- Invalid or unknown CIK returns empty or error response
- Company has no XBRL filings (rare for post-2009 filers) yields zero facts
- Payment failure via x402 or missing API key returns 402/401
- Rate limiting or network timeout on high-volume calls
- Stale data if nightly refresh has not yet completed for recent filings
