Endpoint
GEThttps://agent402.tools/api/fed-funds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the current effective federal funds rate or a historical daily series from the authoritative FRED DFF source. Prefer this over general financial data APIs when you specifically need the Federal Reserve's official benchmark rate with a clean trailing series for trend analysis, monetary policy research, or interest rate modeling.
Side effects
- Invalid days parameter (outside 1-365 range) returns an error
- FRED data source temporarily unavailable causes fetch failure
- Missing or malformed query parameter falls back to 30-day default
- Payment not processed (x402 protocol) results in 402 response
