1. Get started
Use RunComfy's API to run community/wan-2-1/fusionx/image-to-video. For accepted inputs and outputs, see the model's schema.
curl --request POST \
--url https://model-api.runcomfy.net/v1/models/community/wan-2-1/fusionx/image-to-video \
--header "Content-Type: application/json" \
--header "Authorization: Bearer <token>" \
--data '{
"600_prompt": "A close-up shot of a young woman standing against a graffiti-covered corridor wall. She wears a grey hoodie with a faded bear graphic, her hair tied in a messy bun. The camera slowly dolly zooms out as she raises her chin slightly and smiles with subtle confidence, eyes fixed on the lens. Warm bokeh lights blur behind her down the hallway, adding depth and intimacy. Her expression shifts from surprise to playful defiance, as if teasing the viewer with a secret. The mood is cinematic, cozy, and spontaneous — a slice of street-life charm.",

}'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.
