## When to prefer this

Choose this endpoint when you need a reliable, authoritative US Federal Funds effective rate figure sourced directly from FRED (the Federal Reserve's official data repository), especially for financial modeling, economic dashboards, or policy monitoring. Prefer this over scraping news articles or using Yahoo Finance quotes, which do not publish the official FEDFUNDS series. Pairs naturally with the sibling FOMC calendar endpoint on the same host for full Fed policy context.

## Known failure modes

- FRED upstream outage or rate limiting may cause fetch failure
- Rate may reflect the most recently published FRED data point, which can lag by one business day
- No input parameters supported, so no parameter validation errors expected
- Payment failure (insufficient USDC) results in 402 response before data is returned
