The Files API is now generally available on the Claude API. Requests to the /v1/files endpoints, and Messages API requests that reference an uploaded file, no longer require the files-api-2025-04-14 beta header. Requests sent without the header use the GA response format: file expiration (set expires_in_seconds when you upload a file; file objects report expires_at), and page and next_page pagination plus an ids[] filter when you list files. Storage is 1 TB per organization and the rate limit is 500 requests per minute. /v1/files requests that still send the beta header keep working and return the previous response format.
