wan-ai/wan-2-1/image-to-video

Achieve cinematic quality with complex motion, physics-consistent interactions, realistic materials, and flexible styles, delivering coherent scenes and dynamic, expressive visual effects.

1. Get started

Use RunComfy's API to run wan-ai/wan-2-1/image-to-video. For accepted inputs and outputs, see the model's schema.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/wan-ai/wan-2-1/image-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "A bassist plays a low groove in a dimly lit studio. Each pluck causes the string to oscillate dynamically, reacting to tension and damping naturally over time.",
    "image_url": "https://playgrounds-storage-public.runcomfy.net/tools/7012/media-files/usecase1-1-input.jpeg"
  }'

2. Authentication

Set the YOUR_API_TOKEN environment variable with your API key (manage keys in your Profile) and include it on every request as a Bearer token via the Authorization header: Authorization: Bearer $YOUR_API_TOKEN.

3. API reference

Submit a request

Submit an asynchronous generation job and immediately receive a request_id plus URLs to check status, fetch results, and cancel.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/wan-ai/wan-2-1/image-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "A bassist plays a low groove in a dimly lit studio. Each pluck causes the string to oscillate dynamically, reacting to tension and damping naturally over time.",
    "image_url": "https://playgrounds-storage-public.runcomfy.net/tools/7012/media-files/usecase1-1-input.jpeg"
  }'

Monitor request status

Fetch the current state for a request_id ("in_queue", "in_progress", "completed", or "cancelled").

curl --request GET \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/status \
  --header "Authorization: Bearer <token>"

Retrieve request results

Retrieve the final outputs and metadata for the given request_id; if the job is not complete, the response returns the current state so you can continue polling.

curl --request GET \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/result \
  --header "Authorization: Bearer <token>"

Cancel a request

Cancel a queued job by request_id; in-progress jobs cannot be cancelled.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/cancel \
  --header "Authorization: Bearer <token>"

4. File inputs

Hosted file (URL)

Provide a publicly reachable HTTPS URL. Ensure the host allows server-side fetches (no login/cookies required) and isn't rate-limited or blocking bots. Recommended limits: images ≤ 50 MB (~4K), videos ≤ 100 MB (~2–5 min @ 720p). Prefer stable or pre-signed URLs for private assets.
