The background is dimly lit by a flickering flame behind him — ancient carvings and symbols glow faintly on the icy stone wall. Camera slowly pushes in on his face as snow swirls in slow motion, and he breathes heavily, lips slightly parted.Suddenly, subtle glitch effects ripple across his face — like time distorting — as if a divine force is entering his mind.In the distance, an echo of a woman’s voice is heard whispering prophecy. As his eyes narrow, a faint blue rune glow reflects in his iris, foreshadowing something ancient and powerful.The camera holds as his expression changes — from fear… to understanding… to resolve.",

Response Type

Returns: Video

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. 1
    POST /v2/wan-2.2-i2v-flash

    Submitreturns request_id, status_url, response_url

  2. 2
    GET /v2/requests/{id}/status

    Polluntil COMPLETED or FAILED

  3. 3
    GET /v2/requests/{id}

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • 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.
