# Use Ideogram 4.0 with Comfy Router

> Python, TypeScript and cURL snippets for generating images with Ideogram 4.0 over HTTP through Comfy Router, plus the request fields and the result shape

Use Ideogram 4.0 with Comfy Router. Ideogram 4.0 is Ideogram's text-to-image model, which renders legible text inside generated images.

## 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:** `ideogram/ideogram-v4`

**Endpoint:** `POST https://api.comfy.org/v2/models/ideogram/ideogram-v4`

<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(
          "ideogram/ideogram-v4",
          {
              "text_prompt": "a single red maple leaf on a plain white background, studio lighting",
              "resolution": "1024x1024",
              "rendering_speed": "DEFAULT",
          },
          idempotency_key=idempotency_key,
      )

  print("image:", result["data"][0]["url"])
  ```

  ```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.
  type Result = { data: { url: string }[] };
  const idempotencyKey = crypto.randomUUID();
  const { data } = await comfy.models.run<Result>("ideogram/ideogram-v4", {
    text_prompt: "a single red maple leaf on a plain white background, studio lighting",
    resolution: "1024x1024",
    rendering_speed: "DEFAULT",
  }, { idempotencyKey });

  console.log("image:", data.data[0].url);
  ```

  ```bash cURL theme={null}
  # 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/ideogram/ideogram-v4 \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $ROUTER_REQUEST_KEY" \
    -H "Content-Type: application/json" \
    -d "{\"text_prompt\": \"a single red maple leaf on a plain white background, studio lighting\", \"resolution\": \"1024x1024\", \"rendering_speed\": \"DEFAULT\"}"
  ```

## Schema

### Input

<ParamField body="enable_copyright_detection" type="boolean">
  Opt into post-generation copyright detection (Hive likeness and logo checks).
</ParamField>

<ParamField body="json_prompt" type="object">
  Structured V4 prompt. Disables Magic Prompt; consumed directly. Supply exactly one of text\_prompt or json\_prompt.
</ParamField>

<ParamField body="rendering_speed" type="string" default="&#x22;DEFAULT&#x22;">
  The rendering speed setting that controls the trade-off between generation speed and quality

  Possible values: `DEFAULT`, `TURBO`, `QUALITY`
</ParamField>

<ParamField body="resolution" type="string">
  Output resolution in WIDTHxHEIGHT. Omit to let the model pick an aspect ratio. Supported 2K values: 2048x2048, 1440x2880, 2880x1440, 1664x2496, 2496x1664, 1792x2240, 2240x1792, 1440x2560, 2560x1440, 1600x2560, 2560x1600, 1728x2304, 2304x1728, 1296x3168, 3168x1296, 1152x2944, 2944x1152, 1248x3328, 3328x1248, 1280x3072, 3072x1280.
</ParamField>

<ParamField body="text_prompt" type="string">
  Natural-language prompt. Enables Magic Prompt automatically. Supply exactly one of text\_prompt or json\_prompt.
</ParamField>

Generated from the schema Router serves at `GET /v2/models/ideogram/ideogram-v4/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

<ResponseField name="created" type="string (date-time)">
  Timestamp when the generation was created.

  Format: `date-time`
</ResponseField>

<ResponseField name="data" type="object[]">
  Array of generated image information.
</ResponseField>

<ResponseField name="data[].is_image_safe" type="boolean">
  Indicates whether the image is considered safe.
</ResponseField>

<ResponseField name="data[].prompt" type="string">
  The prompt used to generate this image.
</ResponseField>

<ResponseField name="data[].resolution" type="string">
  The resolution of the generated image (e.g., '1024x1024').
</ResponseField>

<ResponseField name="data[].seed" type="integer">
  The seed value used for this generation.
</ResponseField>

<ResponseField name="data[].style_type" type="string">
  The style type used for generation (e.g., 'REALISTIC', 'ANIME').
</ResponseField>

<ResponseField name="data[].url" type="string">
  URL to the generated image.
</ResponseField>

## Examples

### Input

```json theme={null}
{
  "rendering_speed": "DEFAULT",
  "text_prompt": "A poster for a jazz festival, bold typography, warm colours"
}
```

### Output

```json theme={null}
{
  "created": "2026-01-01T00:00:00Z",
  "data": [
    {
      "is_image_safe": true,
      "prompt": "A poster for a jazz festival, bold typography, warm colours",
      "resolution": "2048x2048",
      "seed": 918273645,
      "style_type": "REALISTIC",
      "url": "https://example.invalid/ideogram/ideogram-v4/generated.png"
    }
  ]
}
```

The URL is temporary. Download the image promptly if you need to keep it.

## 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).
