Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/energy-diesel/statusWhen to prefer
Use this endpoint when you need a quick, single-call lookup of the current US retail diesel price denominated in $/gal with its record date, especially in automated pipelines that need commodity fuel price data at very low cost ($0.01 per call). Prefer this over scraping EIA or other sources when a paid, reliable API response is acceptable.
Side effects
- Payment not included or rejected — 402 response blocking access
- Data not yet updated — may return a stale date if the upstream source hasn't refreshed
- Service unavailable on Railway hosting — 5xx error
- No entity found for an invalid query parameter id — empty or error response
