# Use MiniMax H3 Image Highspeed with Comfy Router

> Call minimax/minimax-h3-image-highspeed through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `minimax/minimax-h3-image-highspeed`, served by Comfy Router from MiniMax.

**Input:** Text, Image · **Output:** Image

## Quick start

Create a key in [your Comfy workspace](https://platform.comfy.org/profile/api-keys?onboarding=router) and export it as `COMFY_API_KEY`. The Python and TypeScript snippets use the Comfy SDKs (`pip install comfy-sdk` and `npm install @comfyorg/sdk`); the cURL snippet is the same call over raw HTTP.

**Model ID:** `minimax/minimax-h3-image-highspeed`

**Endpoint:** `POST https://api.comfy.org/v2/models/minimax/minimax-h3-image-highspeed`

> [tab] Wait for the result
>
> ```python Python theme={null}
> from comfy_sdk import Comfy
>
> # Reads COMFY_API_KEY from the environment.
> # The SDK automatically creates an idempotency key and reuses it for automatic retries.
> with Comfy() as client:
>     result = client.models.run(
>         "minimax/minimax-h3-image-highspeed",
>         {
>             "area": "1K",
>             "prompt": "A single red maple leaf resting on a plain white background.",
>         },
>     )
>
> print(result)
> ```
>
> ```typescript TypeScript theme={null}
> import { comfy } from "@comfyorg/sdk";
>
> // Reads COMFY_API_KEY from the environment.
> // The SDK automatically creates an idempotency key and reuses it for automatic retries.
> const { data } = await comfy.models.run("minimax/minimax-h3-image-highspeed", {
>   area: "1K",
>   prompt: "A single red maple leaf resting on a plain white background.",
> });
>
> console.log(data);
> ```
>
> ```bash cURL theme={null}
> curl https://api.comfy.org/v2/models/minimax/minimax-h3-image-highspeed \
>   -H "X-API-Key: $COMFY_API_KEY" \
>   -H "Idempotency-Key: $(uuidgen)" \
>   -H "Content-Type: application/json" \
>   -d "{\"area\": \"1K\", \"prompt\": \"A single red maple leaf resting on a plain white background.\"}"
> ```

> [tab] Queue and collect later
>
> The same body, sent to `POST https://api.comfy.org/v2/models/minimax/minimax-h3-image-highspeed/requests`. Router answers `201` with a `request_id` as soon as the run is admitted, and the result is collected once it is ready, from this process or another one. [Queued delivery](https://docs.comfy.org/development/comfy-router/queue.md) walks through status, cancellation and collection.

## Schema

### Input

**area** `string`

Output area level when `size` is omitted or `auto`. One of `1K`, `2K`, `4K` (default).

**aspect\_ratio** `string`

Output aspect ratio when `size` is omitted or `auto`. `auto` (default) or `X:Y` between 1:3 and 3:1, such as `16:9`.

**disable\_prompt\_enhanced** `boolean` (default: false)

Turns MiniMax's prompt enhancement off. Requires a fixed `size` or an `X:Y` `aspect_ratio`.

**images** `object[]`

Optional reference images. When present the request runs as an image edit, exactly as on the edits route.

**images\[].image\_url** `string` *required*

A public http(s) URL or a `data:image/<format>;base64,` URI. JPEG, PNG, WEBP, HEIC or HEIF, each side 128 to 8192 px, long side at most 4 times the short side.

**model** `string`

Model name. `MiniMax-H3-Image` or `MiniMax-H3-Image-Highspeed`. Router callers may omit this field or send null; Router fills in the model selected by the request path.

**n** `integer` (default: 1)

Number of images. Input tokens are charged once per image.

Range: `1` to `10`

**output\_compression** `integer`

Compression quality for `jpeg` and `webp`, default 95.

Range: `0` to `100`

**output\_format** `string`

Output image format. One of `png`, `jpeg`, `jpg` (default), `webp`.

**prompt** `string` *required*

Text description of the image. With `images`, the description of the edit; the reference images are image 1, image 2 and so on, in array order.

**size** `string`

Output size, `auto` (default) or `WIDTHxHEIGHT` such as `2720x1536`. A fixed size must have an area of 655,360 to 20,000,000 pixels and an aspect ratio between 1:3 and 3:1, and cannot be combined with `aspect_ratio` or `area`.

Generated from the schema Router serves at `GET /v2/models/minimax/minimax-h3-image-highspeed/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

**created** `integer`

Format: `int64`

**data** `object[]`

**data\[].error** `object`

Present only when this image failed or was withheld.

**data\[].error.code** `string`

**data\[].error.message** `string`

**data\[].revised\_prompt** `string`

The prompt MiniMax used for this image.

**data\[].size** `string`

Actual image size as `WIDTHxHEIGHT`.

**data\[].url** `string`

URL of the generated image. It expires, so download the image.

**output\_format** `string`

**request\_id** `string`

**usage** `object`

Token usage of the successful images. Billing is based on it.

**usage.generated\_images** `integer`

**usage.input\_tokens** `integer`

**usage.input\_tokens\_details** `object`

**usage.input\_tokens\_details.image\_tokens** `integer`

**usage.input\_tokens\_details.text\_tokens** `integer`

**usage.output\_tokens** `integer`

**usage.output\_tokens\_details** `object`

**usage.output\_tokens\_details.image\_tokens** `integer`

**usage.total\_tokens** `integer`

## Before you ship

The SDKs create an `Idempotency-Key` and reuse it for automatic retries. For manual retries, reuse the original key. Router can hold the connection for up to 10 minutes.

When a request fails, Router sends an `X-Comfy-Error-Type` response header explaining why. A `422` means Router rejected the input before calling the provider, and a `413` means the request body was larger than Router accepts. Download generated assets promptly because [result URLs can expire](https://docs.comfy.org/development/comfy-router/reference.md#result-assets).

Any size limit named in a field description above is the provider's own bound on that field, quoted from the provider's specification. Router applies a separate cap to the whole request body, which base64-encoded media counts against: see [request body size](https://docs.comfy.org/development/comfy-router/limitations.md#request-bodies-are-capped).

This page documents one partner model called through Comfy Router. The same `comfy-sdk` / `@comfyorg/sdk` package also ships a second client, for running a whole ComfyUI workflow graph on Comfy Cloud: `Comfy(api_key=...)` / `new Comfy({ apiKey })`, with `client.workflows`, `client.assets` and `client.jobs`. See [Comfy SDKs](https://docs.comfy.org/development/api-development/sdks.md).
