## When to prefer this

Use this endpoint when you need the current or most recently reported effective federal funds rate from the Federal Reserve, especially for financial modeling, economic analysis, or monitoring monetary policy. Prefer this over general economic data APIs when you specifically need the fed funds rate with low cost per call via x402 micropayment.

## Known failure modes

- No data available if Federal Reserve has not published a recent rate
- Invalid entityId returns an error or empty result
- Service unavailable (5xx) if the railway.app backend is down
- Payment failure if USDC balance is insufficient for the $0.01 x402 charge
