Supply a valid Bearer API key in the Authorization header.
The account does not have sufficient credits for the request.

Check the model, endpoint or task identifier.
The idempotency key conflicts with another request, or creation is still in progress. Retry only with the same intended body.
Reduce the JSON request size.
Back off before retrying; retain the original idempotency key for the same request.
The service is temporarily unavailable. Retry with backoff and the same idempotency key.
After submitting a task, use the unified query endpoint to check progress and retrieve results:
Keep the returned generation.id and query the task until it reaches a terminal state. Acceptance is not completion; do not submit a new generation simply because the video is still processing.
Manage the secret used to verify generation webhook signatures. Callback URLs are supplied when you create each generation.
Callback URL per generation.
