# Use Grok Imagine Image Quality with Comfy Router

> Call xai/grok-imagine-image-quality through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `xai/grok-imagine-image-quality`, served by Comfy Router from xAI.

## 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:** `xai/grok-imagine-image-quality`

**Endpoint:** `POST https://api.comfy.org/v2/models/xai/grok-imagine-image-quality`

<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(
          "xai/grok-imagine-image-quality",
          {
              # Request fields are the provider's own — see Input below.
          },
      )

  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("xai/grok-imagine-image-quality", {
    // Request fields are the provider's own — see Input below.
  });

  console.log(data);
  ```

  ```bash cURL theme={null}
  # Request fields are the provider's own — see Input below.
  curl https://api.comfy.org/v2/models/xai/grok-imagine-image-quality \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $(uuidgen)" \
    -H "Content-Type: application/json" \
    -d '{}'
  ```

## Schema

### Input

<Note>
  Router has not published an authored input schema for this model yet: `GET /v2/models/xai/grok-imagine-image-quality/openapi.json` returns an open object with `x-comfy-input-schema-authored: false`. Router forwards the body to xAI unchanged, so [xAI's own API reference](https://docs.x.ai/docs/api-reference) is authoritative for the request fields, and nothing is validated server side.
</Note>

### Output

<ResponseField name="block_reason" type="string">
  If the request was blocked by input moderation, contains the block reason
</ResponseField>

<ResponseField name="data" type="object[]">
  A list of generated image objects
</ResponseField>

<ResponseField name="data[].b64_json" type="string">
  A base64-encoded string representation of the generated image in jpeg encoding (if response\_format is b64\_json)
</ResponseField>

<ResponseField name="data[].mime_type" type="string">
  The MIME type of the generated image (e.g. image/png, image/jpeg, image/webp).
</ResponseField>

<ResponseField name="data[].url" type="string">
  A url to the generated image (if response\_format is url)
</ResponseField>

<ResponseField name="usage" type="object">
  Usage information for the image generation request
</ResponseField>

<ResponseField name="usage.cost_in_usd_ticks" type="integer">
  Accurate cost of this request in USD ticks (10,000,000,000 ticks = 1 USD)
</ResponseField>

## Examples

### Output

```json theme={null}
{
  "data": [
    {
      "mime_type": "image/jpeg",
      "url": "https://example.invalid/xai/grok-imagine-image/generated.jpg"
    },
    {
      "mime_type": "image/jpeg",
      "url": "https://example.invalid/xai/grok-imagine-image/generated-2.jpg"
    }
  ],
  "usage": {
    "cost_in_usd_ticks": 200000000
  }
}
```

## 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.
