# Use Text To Video with Comfy Router

> Call moonvalley/text-to-video through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `moonvalley/text-to-video`, served by Comfy Router from Moonvalley.

## 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:** `moonvalley/text-to-video`

**Endpoint:** `POST https://api.comfy.org/v2/models/moonvalley/text-to-video`

<CodeGroup>
  ```python Python theme={null}
  from comfy_sdk import Comfy

  # Reads COMFY_API_KEY from the environment. Each call sends a fresh
  # Idempotency-Key and waits up to 10 minutes for the finished result.
  with Comfy() as client:
      result = client.models.run(
          "moonvalley/text-to-video",
          {
              "prompt_text": "a single red maple leaf",
          },
      )

  print(result)
  ```

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

  // Reads COMFY_API_KEY from the environment. Each call sends a fresh
  // Idempotency-Key and waits up to 10 minutes for the finished result.
  const { data } = await comfy.models.run("moonvalley/text-to-video", {
    prompt_text: "a single red maple leaf",
  });

  console.log(data);
  ```

  ```bash cURL theme={null}
  curl https://api.comfy.org/v2/models/moonvalley/text-to-video \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $(uuidgen)" \
    -H "Content-Type: application/json" \
    -d "{\"prompt_text\": \"a single red maple leaf\"}"
  ```

## Schema

### Input

<ParamField body="image_url" type="string" />

<ParamField body="inference_params" type="object" />

<ParamField body="inference_params.guidance_scale" type="number" default="10">
  Guidance scale for generation control

  Format: `float`
</ParamField>

<ParamField body="inference_params.height" type="integer" default="1080">
  Height of the generated video in pixels
</ParamField>

<ParamField body="inference_params.negative_prompt" type="string">
  Negative prompt text
</ParamField>

<ParamField body="inference_params.seed" type="integer" default="9">
  Random seed for generation (default: random)
</ParamField>

<ParamField body="inference_params.steps" type="integer" default="80">
  Number of denoising steps
</ParamField>

<ParamField body="inference_params.use_negative_prompts" type="boolean" default="true">
  Whether to use negative prompts
</ParamField>

<ParamField body="inference_params.width" type="integer" default="1920">
  Width of the generated video in pixels
</ParamField>

<ParamField body="prompt_text" type="string" />

<ParamField body="webhook_url" type="string" />

Generated from the schema Router serves at `GET /v2/models/moonvalley/text-to-video/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

```json theme={null}
{
  "prompt_text": "a single red maple leaf"
}
```

## Before you ship

The snippets above are the shortest working call. Three things are the same for every model and are documented once on the [Comfy Router headers](/development/comfy-router/headers) page: send an `Idempotency-Key` on every paid call and reuse it when you retry, expect the connection to be held up to Router's 10 minute deadline, and keep `X-Comfy-Request-Id` from every response. The SDKs do all three for you; the cURL tab does none of them. On failure, `X-Comfy-Error-Type` names the bucket, and a `422` means the body failed the model's schema and was never billed.
