Table of contents
1. Get started
Use RunComfy's API to run wan-ai/wan-2-2/lora/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-2-2/lora/image-to-video \
--header "Content-Type: application/json" \
--header "Authorization: Bearer <token>" \
--data '{
"prompt": "The woman is walking slowly",
"image_url": "https://playgrounds-storage-public.runcomfy.net/tools/7002/media-files/usecase5-1-2-input.jpg",
"loras": [
{
"path": "https://huggingface.co/neph1/hard_cut_wan_lora/blob/main/hard_cut_200_wan_i2v_high.safetensors",
"transformer": "both",
"scale": 1
}
]
}'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/lora/image-to-video \
--header "Content-Type: application/json" \
--header "Authorization: Bearer <token>" \
--data '{
"prompt": "The woman is walking slowly",
"image_url": "https://playgrounds-storage-public.runcomfy.net/tools/7002/media-files/usecase5-1-2-input.jpg",
"loras": [
{
"path": "https://huggingface.co/neph1/hard_cut_wan_lora/blob/main/hard_cut_200_wan_i2v_high.safetensors",
"transformer": "both",
"scale": 1
}
]
}'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.
