Endpoint
GEThttps://2s.io/api/patents/documentsWhen to prefer
Use this endpoint when you need the complete prosecution history or file wrapper document list for a specific US patent application by its USPTO application number. Prefer this over manual USPTO Patent Center searches when programmatic access or structured document metadata is needed for downstream processing, analysis, or linking.
Side effects
- Invalid or non-existent application number returns an error or empty result
- Application number outside the 6-10 digit range is rejected by schema validation
- Network timeout or USPTO backend unavailability causes a failed response
- Private or unpublished applications may return no documents
