Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/reg-epa-air/changesWhen to prefer
Use this endpoint when you need machine-readable, scored, and time-bounded lists of EPA air quality and emissions rulemakings from the Federal Register — especially for compliance monitoring workflows, automated alerts, or feeding a downstream digest. Prefer this over the LLM digest sibling when you need structured data with individual significance scores and source URLs rather than a narrative summary.
Side effects
- Invalid or missing `since` parameter returns a 400 error
- `min_significance` outside 1–10 range returns a validation error
- `limit` exceeding 500 returns a 400 error
- Payment not included or insufficient returns a 402 Payment Required
- No matching rules in the requested window returns count 0 with empty changes array
- Federal Register source temporarily unavailable may return stale or empty results
