# Use Kling V3 with Comfy Router

> Call kling/kling-v3 through Comfy Router: endpoint, request shape and the response Router returns.

Use `kling/kling-v3` with the Comfy Router API. Kling 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](https://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:** `kling/kling-v3`

**Endpoint:** `POST https://api.comfy.org/v2/models/kling/kling-v3`

<CodeGroup>
  ```python Python theme={null}
  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(
          "kling/kling-v3",
          {
              # Request fields are the provider's own — see Input below.
          },
          idempotency_key=idempotency_key,
      )

  print(result)
  ```

  ```typescript TypeScript theme={null}
  import { comfy } from "@comfyorg/sdk";

  // Reads COMFY_API_KEY from the environment. Save this key and reuse it if you
  // retry this request after the SDK returns an error.
  const idempotencyKey = crypto.randomUUID();
  const { data } = await comfy.models.run("kling/kling-v3", {
    // Request fields are the provider's own — see Input below.
  }, { idempotencyKey });

  console.log(data);
  ```

  ```bash cURL theme={null}
  # Request fields are the provider's own — see Input below.
  # Run this line once. Reuse ROUTER_REQUEST_KEY if you retry the curl command.
  ROUTER_REQUEST_KEY=$(uuidgen)
  curl https://api.comfy.org/v2/models/kling/kling-v3 \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $ROUTER_REQUEST_KEY" \
    -H "Content-Type: application/json" \
    -d '{}'
  ```

## Schema

### Input

<Note>
  Router has not published an authored input schema for this model yet: `GET /v2/models/kling/kling-v3/openapi.json` returns an open object with `x-comfy-input-schema-authored: false`. Router forwards the body to Kling unchanged, so [Kling's own API reference](https://app.klingai.com/global/dev/document-api) 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](/development/comfy-router/reference#result-assets).
