Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/gdpWhen to prefer
Use this endpoint when you need authoritative, FRED-sourced US real GDP data for macroeconomic analysis, forecasting context, or economic dashboards — especially when you need both the headline figure and recent quarterly history in one call without needing a ticker symbol. Prefer this over general financial data APIs when FRED provenance and chained-dollar real GDP specifically are required.
Side effects
- FRED data temporarily unavailable — upstream outage from St. Louis Fed
- Payment failure — insufficient USDC balance or x402 payment not accepted
- Stale data — FRED may lag by one quarter during release windows
- HTTP 402 if payment header is missing or malformed
- Empty history array if FRED series has no recent data points
