Upload Asset

Changed on

Uploads a file (image, video, audio, PDF, or SRT subtitle) and returns an asset_id for use in other endpoints. Max 50 MB, or 32 MB for an image. Supported types: png, jpeg, mp4, webm, mp3, wav, pdf, srt. A file is checked against the content policy after it is uploaded; if it is blocked, the asset is removed and later requests for it return not found.

Headers

Idempotency-Keystring

Optional client-supplied key for safely retrying mutations. Subsequent calls within 24 hours that share this key replay the original response — even if the request body differs slightly (a warning is logged). A retry that arrives while the original is still in flight gets a 409 request_in_progress. Keys must be 1–255 characters from [A-Za-z0-9_:.-]; a UUID is a safe default. Scope is per-endpoint and per-resource: the same key on a different route or path parameter is independent.

Request body multipart/form-data

filestring binary required

File to upload (image, video, audio, PDF, or SRT subtitle). Max 50 MB, or 32 MB for an image.
