Produce high-fidelity clips with strong prompt control, adjustable aspect ratios, seeds, and optional magic prompt for richer cinematic detail.

1. Get started

Use RunComfy's API to run wan-ai/wan-2-2/text-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-2-2/text-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "Edge light, low contrast, medium close-up, daylight, left-heavy composition, clean single shot, warm tone, soft light, sunny light, side light, daytime. A young girl sits in a field of tall grass with two fluffy donkeys behind her. She is about 11 or 12 years old, wearing a floral dress, with braided pigtails and a pure smile. She gently plays with wildflowers beside her. Sunlight casts a natural, warm tone across the field."
  }'

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-2-2/text-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "Edge light, low contrast, medium close-up, daylight, left-heavy composition, clean single shot, warm tone, soft light, sunny light, side light, daytime. A young girl sits in a field of tall grass with two fluffy donkeys behind her. She is about 11 or 12 years old, wearing a floral dress, with braided pigtails and a pure smile. She gently plays with wildflowers beside her. Sunlight casts a natural, warm tone across the field."
  }'

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.
