Use Seedvr 2 with Comfy Router

Call wavespeed/seedvr2 through Comfy Router: endpoint, request shape and the response Router returns.

Use wavespeed/seedvr2 with the Comfy Router API. WaveSpeed 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: wavespeed/seedvr2

Endpoint: POST https://api.comfy.org/v2/models/wavespeed/seedvr2

Python

import uuid
from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment. Store this UUID before starting a
# generation. Use the same value if you retry it.
idempotency_key = str(uuid.uuid4())
with Comfy() as client:
    result = client.models.run(
        "wavespeed/seedvr2",
        {
            "image": "https://images.pexels.com/photos/346529/pexels-photo-346529.jpeg",
            "target_resolution": "4k",
        },
        idempotency_key=idempotency_key,
        timeout=660.0,
    )

print(result)

Schema

Input

enable_base64_output · boolean · default: "false"

If enabled, the output will be encoded into a BASE64 string instead of a URL.

image · string · required

The URL of the image to upscale.

output_format · string · default: "\"jpeg\""

The format of the output image.

Possible values: jpeg, png, webp

target_resolution · string · default: "\"4k\""

The target resolution of the output image.

Possible values: 2k, 4k, 8k

Generated from the schema Router serves at GET /v2/models/wavespeed/seedvr2/openapi.json, the same document it validates a call against before the request reaches the provider.

Output

Router does not publish an output schema for this model.

Examples

Input

{
  "image": "https://images.pexels.com/photos/346529/pexels-photo-346529.jpeg",
  "target_resolution": "4k"
}

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.

When a request fails, Router sends an X-Comfy-Error-Type response header explaining why. 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

Model discovery, validation errors, retries, and billing.
