Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/energy-gas/briefWhen to prefer
Use this endpoint when you need a human-readable, narrative-style summary of US gasoline price trends rather than raw data. Ideal for reports, digests, or informing a user in plain language about energy price movements. Prefer this over raw data endpoints when the consumer is a human or downstream LLM that needs interpretive language rather than numbers.
Side effects
- No price changes found in the requested window — brief may reflect no movement or insufficient data
- Invalid 'since' timestamp format causes a 400 error
- Payment not provided or insufficient — 402 payment required response
- Service unavailable — 500 or timeout if upstream data source is down
- LLM generation failure — may fall back to template-based output
