Example use cases
Example prompt

Technical details
Endpoint
GEThttps://stablefinance.dev/api/financial-metricsWhen to prefer
Use this endpoint when you need structured financial ratios and metrics for publicly traded US companies, especially when you want SEC-sourced data like margins, valuation ratios, leverage ratios, and growth rates across annual, quarterly, or TTM periods. Prefer this over raw SEC EDGAR queries when you need pre-computed ratios and metrics without parsing raw filings yourself.
Side effects
- Missing required 'period' parameter returns a validation error
- Invalid ticker symbol returns empty financial_metrics array or 404
- CIK not found returns empty results
- Report period date range yields no matching filings
- Limit parameter out of range (must be 1-50) causes schema validation failure
- Payment not made or x402 handshake fails results in 402 Payment Required response
- Network timeout on Financial Datasets AI upstream
