She is dressed casually in a fitted blazer and a neutral-toned shirt, exuding confidence and professionalism. The studio is warmly lit, with soft overhead lighting and accent lights creating a cozy ambiance. In the background, a soundproofed wall with stylish acoustic panels is visible, along with a small shelf holding books and a potted plant. A laptop sits on the desk in front of her, alongside a cup of coffee and a notebook with scribbled notes. The camera angle is a medium close-up, focused on her upper body and face as she engages in a lively conversation, her expressive hands occasionally gesturing while she speaks. The scene is vibrant and modern, capturing the energy of a podcast recording in progress.",

Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/wan2.1-i2v-720pSubmit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
