Get an API key, submit an ffmpeg job, poll until complete, download the output.

3. Poll for completion

Statuses: waiting → dispatched → running → complete | failed | cancelled. See job lifecycle for what each status means. Poll every 1–2 seconds. For push instead of poll, configure a webhook.

4. Download the result

Every job type returns this same output shape: data for a computed answer, file for the headline result, files for the full list. Re-fetch the job to refresh the URLs after they expire.
