How this service works
AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.
Output
Returns a JSON object containing an array of computed financial ratios (e.g. net_margin_pct, debt_to_equity) each with the ratio name, numeric value, definition, and the underlying numerator/denominator metric names and values. Also includes the company CIK, fiscal period end date, computation method identifier, as-of timestamp, a disclaimer, and a list of any missing inputs that caused nulls.
Example use cases
Fundamental analysis for stock screening
“Get me the key financial ratios for Apple — net margin, debt-to-equity — derived from their latest SEC 10-K filing so I can compare them against sector benchmarks.”
Automated earnings report summary
“After Tesla's latest 10-K was filed, pull their XBRL-derived profitability ratios like net margin and revenue figures so I can summarize their financial health for my newsletter.”
Due diligence on a potential investment
“I'm researching Microsoft before investing — can you fetch their computed financial ratios from SEC EDGAR, including margins and leverage multiples from the most recent fiscal year?”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/xbrl/ratiosWhen to prefer
Choose this endpoint when you need structured, computation-ready financial ratios derived directly from SEC EDGAR XBRL data with full provenance and per-metric sourcing. Prefer it over scraping financial data sites when you need machine-readable JSON with numerator/denominator transparency, or when building automated pipelines that require traceable, as-filed figures rather than third-party-adjusted numbers.
Side effects
- Unknown ticker returns HTTP 422 with error detail
- CIK not found in EDGAR returns 422
- Both cik and ticker provided simultaneously returns 422 (provide exactly one)
- Company has not filed XBRL data — ratios return null for affected fields
- Fiscal period mismatch causes individual ratio values to be null rather than cross-year mixed
- Payment failure or insufficient credits returns 402 Payment Required
