Create Video Generation
Create a BytePlus Seedance video generation task.
Returns immediately with {"id": "<task_id>"}.
Poll GET /v1/video/generations/{id} until status is
succeeded, failed, or expired.
Pass callback_url to receive a POST notification when the task
status changes. We intercept the BytePlus callback, update our DB,
then forward the full task payload to your URL.
Authorizations
Enter your MeshAPI key (rsk_...) — sent as Authorization: Bearer <key>.
Headers
Dated version of the API contract to pin this request to. Omit it and the request is served under 2026-08 — the oldest supported version, so an existing integration is never moved by a release. A malformed or unsupported value is rejected with 400 invalid_api_version rather than falling back silently. The version actually served is echoed as X-Mesh-Version on every response, including errors.
