}'Video async flow
All requests go to https://api.lumeapi.site/v1 with Authorization: Bearer sk-…
(1) POST /v1/videos → save id from response. (2) GET /v1/videos/{id} every 5–15s until status is completed or failed. (3) On completed, GET /v1/videos/{id}/content to download MP4.
Poll and download with the id returned by POST /v1/videos (e.g. task_Fk6QrnX6…). This is the only task id your client needs.
Poll every 5–15 seconds with back-off. Typical completion: 30s–5min depending on model. Stop after 15–30 minutes if still not completed.
When status=failed, read error.message. Do not call /content. Submit a new POST /v1/videos to retry.
Balance is debited when POST /v1/videos returns 200. Poll until completed or failed before treating the job as successful.
