Use Ideogram 4.0 with Comfy Router

API Reference for Ideogram 4.0. Ideogram 4.0 is Ideogram’s text-to-image model, which renders legible text inside generated images.

Comfy Router is not generally available yet. POST /v2/models/{provider}/{model} and its catalog and schema siblings are not serving requests yet: an authenticated call answers 404 today. The snippets on this page document the contract those routes will serve, published ahead of the rollout so your integration is ready to write against.

Quick start

Create a key at 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

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

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

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.
type Result = { data: { url: string }[] };
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",
});

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

curl https://api.comfy.org/v2/models/ideogram/ideogram-v4 \
  -H "X-API-Key: $COMFY_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -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

boolean

Opt into post-generation copyright detection (Hive likeness and logo checks).

object

Structured V4 prompt. Disables Magic Prompt; consumed directly. Supply exactly one of text_prompt or json_prompt.

string

default:"\"DEFAULT\""

The rendering speed setting that controls the trade-off between generation speed and qualityPossible values: DEFAULT, TURBO, QUALITY

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.

string

Natural-language prompt. Enables Magic Prompt automatically. Supply exactly one of text_prompt or json_prompt.

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

string (date-time)

Timestamp when the generation was created.Format: date-time

object[]

Array of generated image information.

boolean

Indicates whether the image is considered safe.

string

The prompt used to generate this image.

string

The resolution of the generated image (e.g., ‘1024x1024’).

integer

The seed value used for this generation.

string

The style type used for generation (e.g., ‘REALISTIC’, ‘ANIME’).

string

URL to the generated image.

Examples

Input

{
  "rendering_speed": "DEFAULT",
  "text_prompt": "A poster for a jazz festival, bold typography, warm colours"
}

Output

{
  "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

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 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.

Headers

Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.

Quick Start

Typed error handling in Python and TypeScript, reading the 422, walking the catalog.

Limitations

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