Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/court-opinions/changesWhen to prefer
Use this endpoint when you need to monitor or retrieve newly published US court opinions since a specific point in time, especially for litigation monitoring, legal research pipelines, or compliance workflows that care about new case law. Prefer this over Federal Register endpoints when the focus is on court decisions rather than regulatory rules, and over general legal databases when you need a lightweight, timestamped change feed with significance scoring powered by CourtListener data.
Side effects
- COURTLISTENER_API_TOKEN not set — endpoint is a no-op and returns empty results
- Invalid or missing 'since' parameter causes a 400 error
- 'since' timestamp in wrong format (not ISO-8601) causes a validation error
- Limit exceeds 500 or is below 1 causes a schema validation error
- CourtListener upstream API is unavailable, resulting in a 502 or empty response
- min_significance out of range (not 1-10) causes a validation error
