Use Wan 2.7 I2V with Comfy Router

Call wan/wan2.7-i2v through Comfy Router: endpoint, request shape and the response Router returns.

Use wan/wan2.7-i2v with the Comfy Router API. Wan provides the model; Router gives it the shared authentication and request route below.

Quick start

Create a key at platform.comfy.org/profile/api-keys and export it as COMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP.

Model ID: wan/wan2.7-i2v

Endpoint: POST https://api.comfy.org/v2/models/wan/wan2.7-i2v

Python

import uuid
from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment. Save this key and reuse it if you
# retry this request after the SDK returns an error.
idempotency_key = str(uuid.uuid4())
with Comfy() as client:
    result = client.models.run(
        "wan/wan2.7-i2v",
        {
            # Request fields are the provider's own — see Input below.
        },
        idempotency_key=idempotency_key,
    )

print(result)

Schema

Input

Router has not published an authored input schema for this model yet: GET /v2/models/wan/wan2.7-i2v/openapi.json returns an open object with x-comfy-input-schema-authored: false. Router forwards the body to Wan unchanged, so Wan’s own API documentation is authoritative for the request fields, and nothing is validated server side.

Before you ship

Save one Idempotency-Key for each call and reuse it for retries. Router can hold the connection for up to 10 minutes. The SDKs handle authentication; raw HTTP clients send the headers themselves.

Use X-Comfy-Error-Type to classify a failure. A 422 means Router rejected the input before calling the provider. Download generated assets promptly because result URLs can expire.

Headers

Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.

Using the Router API

Find models, inspect schemas, and retry safely.

Limitations

What Router does not do today, and what to use instead.
