Extreme photoreal 4K, cinematic lighting, subtle film grain, smooth camera. No subtitles, no UI, no watermark.\nShot 1 [0-3s] Macro close-up on the caveman's weathered face and hairy knuckles clutching a jagged stone axe in a misty prehistoric dawn. He grunts deeply: \"Better!\"\nShot 2 [3-6s] Hard cut: Bustling ancient forge at golden hour, sparks flying. The caveman, now in leather tunic with a bronze sword, hammers metal confidently. Camera dollies in as he bellows: \"Faster!\"\nShot 3 [6-10s] Hard cut: Steampunk factory amid rainy industrial night, gears whirring. He transforms into a suited inventor with goggles, cranking a massive machine that hums to life. Slow zoom on his evolving eyes as he commands: \"Smarter!\"\nShot 4 [10-15s] Hard cut: Futuristic AI lab bathed in neon glow, holographic interfaces pulsing. The caveman, sleek in neural-linked exosuit, interfaces with a glowing orb; his form subtly digitizes. He smiles knowingly: \"Evolved. What's next?\"",

enable_prompt_expansionoptional
boolean

If set to true, the prompt optimizer will be enabled

Default: true

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-2.6-t2v

    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.
