# Use MiniMax H3 with Comfy Router

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

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

## Request setup

Create a key in [your Comfy workspace](https://platform.comfy.org/profile/api-keys) and export it as `COMFY_API_KEY`. For Python, run `pip install comfy-sdk`. For TypeScript, run `npm install @comfyorg/sdk`. cURL uses raw HTTP.

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

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

<Note>
  This model has no runnable request example. Build the body from the input documentation below, then use it with the [Router quickstart](/development/comfy-router/quickstart).
</Note>

## Schema

### Input

<Note>
  Router has not published an authored input schema for this model yet: `GET /v2/models/minimax/minimax-h3/openapi.json` returns an open object with `x-comfy-input-schema-authored: false`. Router forwards the body to MiniMax unchanged, so [MiniMax's own API reference](https://platform.minimax.io/docs/api-reference) is authoritative for the request fields, and Router does not perform model-specific input validation. Provider validation still applies.
</Note>

## 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. Download generated assets promptly because [result URLs can expire](/development/comfy-router/reference#result-assets).
