Files API is out of beta on the Claude API

GAVerifiedAdded Sep 22, 2026

/v1/files and Messages requests referencing uploaded files no longer need the files-api-2025-04-14 header. Headerless requests get file expiration via expires_in_seconds, page-based pagination and an ids[] filter; requests with the header keep working.
