Infringement Claims
Contest an infringement claim
Submit a written response and supporting documents disputing the claim. The first call moves the claim from pending to contested; subsequent calls append supplementary evidence without changing status. The documents[] you attach are aggregated across rounds in the claim's contest_documents field.
Only pending and contested claims accept new evidence. A resolved claim returns 400.
Failure modes:
- 400 - the claim is resolved (terminal); cannot be contested further.
- 404 - the claim does not exist or is not against a DIR you own.
- 422 - contest_notes is too short (< 10 chars), too long (> 2000 chars), documents is > 20 entries, or a document_id is duplicated within the same submission.
