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. +Agent Skills +and the Skills API ( +/v1/skills +) are now generally available on the Claude API. Requests no longer require the +skills-2025-10-02 +beta header, including Messages API requests that load Skills through the +container +parameter.
