# 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.

## Quick start

Create a key in [your Comfy workspace](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:** `minimax/minimax-h3`

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

<CodeGroup>
  ```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",
          {
              "content": [
                  {
                      "text": "A single red maple leaf resting on a plain white background.",
                      "type": "text",
                  },
              ],
              "duration": 5,
              "ratio": "16:9",
              "resolution": "768P",
          },
      )

  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", {
    content: [
      {
        text: "A single red maple leaf resting on a plain white background.",
        type: "text",
      },
    ],
    duration: 5,
    ratio: "16:9",
    resolution: "768P",
  });

  console.log(data);
  ```

  ```bash cURL theme={null}
  curl https://api.comfy.org/v2/models/minimax/minimax-h3 \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $(uuidgen)" \
    -H "Content-Type: application/json" \
    -d "{\"content\": [{\"text\":\"A single red maple leaf resting on a plain white background.\",\"type\":\"text\"}], \"duration\": 5, \"ratio\": \"16:9\", \"resolution\": \"768P\"}"

</ParamField>

<ParamField body="content[].role" type="string">
  Role of a media item. Options: first\_frame, last\_frame, reference\_image, reference\_video, reference\_audio, base\_video. Keyframe roles and reference\_\* roles are mutually exclusive within a request; base\_video marks the source video of a video regeneration request.
</ParamField>

<ParamField body="content[].text" type="string">
  The prompt text. Exactly one non-empty text item is required per request.
</ParamField>

<ParamField body="content[].type" type="string" required>
  Content item type. Options: text, image\_url, video\_url, audio\_url.
</ParamField>

<ParamField body="content[].video_url" type="object">
  Video source. Required for video\_url items.
</ParamField>

<ParamField body="content[].video_url.url" type="string">
  A publicly reachable URL, an mm\_file://\{file\_id} reference, or a data URI.
</ParamField>

<ParamField body="duration" type="integer" required>
  Video length in seconds, 5 to 15.
</ParamField>

<ParamField body="model" type="string">
  ID of model. Options: MiniMax-H3. Router callers may omit this field or send null; Router injects the model selected by the request path before provider dispatch.
</ParamField>

<ParamField body="ratio" type="string">
  Aspect ratio. Options: adaptive (default), 21:9, 16:9, 4:3, 1:1, 3:4, 9:16. Required and must not be adaptive for text-to-video; ignored (treated as adaptive) for first-frame or last-frame generation.
</ParamField>

  Video resolution. Options: 2K, 768P.
</ParamField>

<ParamField body="seed" type="integer">
  Random seed in \[-1, 2^32 - 1]; omitted or -1 is random.

  Format: `int64`
</ParamField>

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

## 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).
