When to Use

Use this skill when:

Getting API Key

1. Visit https://monet.vision to register an account 2. After login, go to https://monet.vision/skills/keys to create an API Key 3. Configure the API Key in environment variables or code

If you don't have an API Key, ask your owner to apply at monet.vision.

Quick Start

Create a Video Generation Task

curl -X POST https://monet.vision/api/v1/tasks/async \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $MONET_API_KEY" \
  -d '{
    "type": "video",
    "input": {
      "model": "veo-3-1",
      "prompt": "A cat running in the park",
      "duration": 8,
      "aspect_ratio": "16:9"
    },
    "idempotency_key": "unique-key-123"
  }'

> ⚠️ Important: idempotency_key is required. Use a unique value (e.g., UUID) to prevent duplicate task creation if the request is retried.

Response:

{
  "id": "task_abc123",
  "status": "pending",
  "type": "video",
  "created_at": "2026-02-27T10:00:00Z"
}

Get Task Status and Result

Task processing is asynchronous. You need to poll the task status until it becomes success or failed. Recommended polling interval: 5 seconds.

curl https://monet.vision/api/v1/tasks/task_abc123 \
  -H "Authorization: Bearer $MONET_API_KEY"

Response when completed:

{
  "id": "task_abc123",
  "status": "success",
  "type": "video",
  "outputs": [
    {
      "model": "veo-3-1",
      "status": "success",
      "progress": 100,
      "url": "https://files.monet.vision/..."
    }
  ],
  "created_at": "2026-02-27T10:00:00Z",
  "updated_at": "2026-02-27T10:01:30Z"
}

Example: Poll until completion

const TASK_ID = "task_abc123";
const MONET_API_KEY = process.env.MONET_API_KEY;
async function pollTask() {
  while (true) {
    const response = await fetch(
      https://monet.vision/api/v1/tasks/${TASK_ID},
      {
        headers: {
          Authorization: Bearer ${MONET_API_KEY},
        },
      },
    );
    const data = await response.json();
    const status = data.status;
    if (status === "success") {
      console.log("Task completed successfully!");
      console.log(JSON.stringify(data, null, 2));
      break;
    } else if (status === "failed") {
      console.log("Task failed!");
      console.log(JSON.stringify(data, null, 2));
      break;
    } else {
      console.log(Task status: ${status}, waiting...);
      await new Promise((resolve) => setTimeout(resolve, 5000));
    }
  }
}
pollTask();
