Use Veo 2.0 Generate 001 with Comfy Router

Call veo/veo-2.0-generate-001 through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for veo/veo-2.0-generate-001, served by Comfy Router from Veo.

Quick start

Create a key in your Comfy workspace 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: veo/veo-2.0-generate-001

Endpoint: POST https://api.comfy.org/v2/models/veo/veo-2.0-generate-001

Python

from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment.
# The SDK automatically creates an idempotency key and reuses it for automatic retries.
with Comfy() as client:
    result = client.models.run(
        "veo/veo-2.0-generate-001",
        {
            "instances": [
                {
                    "prompt": "a single red maple leaf falling onto still water, slow motion",
                },
            ],
            "parameters": {
                "durationSeconds": 6,
                "sampleCount": 1,
            },
        },
    )

print(result)

Schema

Input

instances · object[]

instances[].image · object

Optional image to guide video generation

instances[].image.bytesBase64Encoded · string (byte)

Format: byte

instances[].image.gcsUri · string

instances[].image.mimeType · string

instances[].prompt · string · required

Text description of the video

parameters · object

parameters.aspectRatio · string

parameters.durationSeconds · integer

parameters.enhancePrompt · boolean

parameters.negativePrompt · string

parameters.personGeneration · string

Controls people in generated videos. dont_allow, allow_adult and allowAll are Vertex AI’s own spellings and are the ones VeoGenVidRequest publishes for the same field. ALLOW and BLOCK are kept for compatibility with clients generated from this component before it was Router-authored — see the note at the top of Veo2GenVidRequest.

Possible values: ALLOW, BLOCK, dont_allow, allow_adult, allowAll

parameters.sampleCount · integer

parameters.seed · integer

Format: uint32

parameters.storageUri · string

Optional Cloud Storage URI to upload the video

Generated from the schema Router serves at GET /v2/models/veo/veo-2.0-generate-001/openapi.json, the same document it validates a call against before the request reaches the provider.

Output

done · boolean

Whether the operation has completed

error · object

name · string

Operation resource name

response · object

The prediction response, present when done is true

response.@type · string

response.raiMediaFilteredCount · integer

Number of videos filtered by responsible AI policies

response.raiMediaFilteredReasons · string[]

Reasons why videos were filtered by responsible AI policies

response.videos · object[]

response.videos[].bytesBase64Encoded · string

Base64-encoded video content

response.videos[].gcsUri · string

Cloud Storage URI of the generated video

response.videos[].mimeType · string

Video MIME type (video/mp4)

Before you ship

The SDKs create an Idempotency-Key and reuse it for automatic retries. For manual retries, reuse the original key. Router can hold the connection for up to 10 minutes.

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.

Limitations

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