alibaba/wan-3.0-pro-prime/image-to-video

Wan 3.0 Pro Prime image-to-video animates an opening frame at 1080p, 2K or 4K for 2 to 30 seconds, with generated audio. An optional last frame fixes the ending, and 2K and 4K are enlarged from a native 1080p render.

Send a request

Quickstart

Examples use the selected endpoint’s public parameter definitions. Replace the API key and example media, then send the request from your server.

SDKs & integrations
POSThttps://api.spicyapi.ai/api/v1/jobs/createTask

API authentication

Keep the API key in the server environment variable SPICY_API_KEY. Use Bearer authentication and Content-Type: application/json for JSON requests.

Authorization: Bearer $SPICY_API_KEY

# Generate the idempotency key once; reuse it when retrying after a lost response.

Generated from this model’s input schema — the same one the API validates every request against.

Input parameters

Place these fields inside the request body’s input object. Names and types match the API. Do not assume a default when none is specified.

image_urlstringRequired

The opening frame, used exactly as the first frame, and the real quality ceiling of the shot. Wardrobe, body, set and light direction are inherited from it, so the prompt only has to carry motion. JPEG, PNG without transparency, BMP or WEBP; 240 to 8000 px per side, aspect ratio no wider than 8:1, 20 MB at most.

Default
Not specified
Constraints
minLength:1
format:"uri"
contentMediaType:["image/jpeg","image/png","image/webp","image/gif"]
seedintegerOptional

0 to 2147483647. Fix it while you tune resolution or duration, otherwise every rerun changes two things at once.

Default
Not specified
Constraints
minimum:0
maximum:2147483647
enable_prompt_expansionbooleanOptional

On by default on this family. It fills out thin briefs and rewrites detailed ones, so turn it off once your prompt is a precise shot description.

Default
true
generate_audiobooleanOptional

On by default. Sound is generated with the picture and arrives inside the same file. Set false when a composer is scoring the spot.

Default
true
duration_secondsintegerOptionalAffects price

Any whole number from 2 to 30, default 5, or -1 for smart duration, where the model picks the length: the 30-second maximum is reserved up front and the charge settles on the length actually delivered. Find the shot at 5 seconds and 1080p before you spend a 30-second 4K render on it.

Default
5
Allowed values
-123456789101112131415161718192021222324252627282930
aspect_ratiostringOptional

adaptive follows the opening frame. Pin a ratio only when the delivery format demands it.

Default
"adaptive"
Allowed values
"16:9""4:3""1:1""3:4""9:16""adaptive"
resolutionstringOptionalAffects price

1080p, 2k or 4k, default 1080p. A native Wan 3.0 Prime render tops out at 1080p, so the tiers above it — 2k and 4k — are delivered by enlarging that render instead of rendering natively at those sizes: the extra pixels come from the enlargement, and they are only as good as the render underneath. There is no 480p or 720p tier here; for those sizes, use Wan 3.0 or Wan 3.0 Prime.

Default
"1080p"
Allowed values
"1080p""2k""4k"
last_image_urlstringOptional

Optional, and only together with image_url. The clip ends exactly on this image — it is used as the last frame, not as loose guidance — so supply it when the shot has to land on a fixed composition, such as a product back on its hero angle. Same file limits as image_url.

Default
Not specified
Constraints
minLength:1
format:"uri"
contentMediaType:["image/jpeg","image/png","image/webp","image/gif"]
promptstringOptional

Optional here. Use it for motion and camera; restating what is already visible in the frame invites the model to redraw it.

Track the task

HTTP 202 means the task was accepted, not completed. Save the returned taskId and query that task. Do not create another task while waiting for its result.

Accepted response
HTTP/1.1 202 Accepted
Location: /api/v1/jobs/recordInfo?taskId=job_01k3m8x9q2z4v7n5p6r8s0t1w3

{
  "code": 200,
  "msg": "success",
  "request_id": "req_example_create",
  "data": {
    "taskId": "job_01k3m8x9q2z4v7n5p6r8s0t1w3",
    "state": "queued",
    "estimatedCost": "0.750000"
  }
}

The accepted response includes the estimate so your app can show the same amount in task history and billing.

Read the job
curl --get "https://api.spicyapi.ai/api/v1/jobs/recordInfo" \
  --data-urlencode "taskId=$TASK_ID" \
  -H "Authorization: Bearer $SPICY_API_KEY"

Start polling at about 2 seconds and gradually increase the interval. Stop at a terminal state. After a connection failure, query the original taskId. Retry creation only with the original idempotency key and body.

Or let the callback find you
import { verifyWebhook } from "@spicyapi/sdk";

// express.raw keeps the bytes we signed; express.json never matches.
app.post("/hooks/spicy", express.raw({ type: "application/json" }), (req, res) => {
  const { payload } = verifyWebhook({
    rawBody: req.body,
    timestamp: req.header("X-Webhook-Timestamp"),
    signature: req.header("X-Webhook-Signature"),
    payloadVersion: Number(req.header("X-Webhook-Payload-Version")),
    secret: process.env.SPICY_WEBHOOK_SECRET,
  });
  res.status(200).end();
  void handleFinishedTask(payload);
});

Pass callBackUrl when you create the task and the finished record is POSTed to you — no polling loop at all. Every delivery carries X-Webhook-Timestamp, X-Webhook-Signature and X-Webhook-Payload-Version. The signature is a base64 HMAC-SHA256 over taskId.timestamp.sha256(body), so it must be checked against the raw bytes: parsing the JSON and re-serialising it changes them and the check will fail. Failed deliveries are retried, so the same taskId can arrive twice — make the handler idempotent. Answer 2xx first and do the work afterwards; a slow handler is treated as a failed delivery.

Read the result

Consume output only when state is succeeded. On failure, use errorCode, errorMessage and request_id to investigate. Example costs and states do not represent an actual bill.

    "completedAt": "2026-08-28T12:00:30Z"
  }
}

For each available asset, open or download assets[].url directly without an API Authorization header. The signed URL expires at expiresAt; poll the task again to refresh it while the asset remains within its retention period. A pending or unavailable asset has no URL. Treat signed URLs as private.
