## When to prefer this

Choose this endpoint when you need a quick, paid-per-call lookup of the US Gulf Coast kerosene jet fuel spot price (EIA DJFUELUSGULF) with recent history — particularly for logistics cost modeling, aviation fuel benchmarking, or energy market monitoring. It is specifically a US Gulf Coast benchmark, not a Jet-A1 European index or an IATA fuel price, so prefer alternatives if you need European refinery pricing or IATA benchmarks.

## Known failure modes

- FRED/EIA data not yet updated for today — latest date may lag by 1–2 business days
- Invalid 'days' parameter (outside 1–30 range) may return an error or default behavior
- Cloudflare Worker upstream timeout if FRED API is slow
- Weekend or holiday gaps in price data — FRED series may not report daily on non-trading days
- Network error returning 5xx from the worker host
