HTTP 202 means the job is queued. Save id and poll_url, then poll with the same API key until completed or failed. A successful video response contains video_url. Download the output within 24 hours. A polling timeout does not cancel the job; resume using the saved poll_url.

text-to-video requires a prompt. image-to-video requires first_frame and allows last_frame. reference-to-video requires at least one reference array. Do not mix keyframes and reference arrays. Use publicly accessible media URLs; region can be auto.duration = -1 selects smart duration. Reference video time plus generated video time must fit within 30 seconds. Image references accept public URLs or Base64 (JPEG, PNG, BMP, WebP data URIs). Video and audio references require accessible URLs. The gateway checks media type and reference video duration before submission.
