Pricing

The Wan 2.2 API uses a credit-based pricing model. Credits are consumed based on the complexity and duration of the generated content.

API Endpoints

The Wan 2.2 API is available through our unified GraphQL endpoint.

GraphQL Endpoint

POST https://api.doitong.com/graphql

REST Endpoint

POST https://api.doitong.com/v1/text_to_video

Parameters

Available parameters for Wan 2.2 API requests:

Response Format

All API responses follow a consistent format:

Success Response

{
  "data": {
    "generatevideo": {
      "id": "abc123xyz",
      "status": "processing",
      "url": null,
      "webhookUrl": "https://your-webhook.com/callback",
      "createdAt": "2024-01-01T00:00:00Z"
    }
  }
}

Completed Response

{
  "data": {
    "generatevideo": {
      "id": "abc123xyz",
      "status": "completed",
      "url": "https://cdn.doitong.com/outputs/abc123xyz.mp4",
      "duration": 5,
      "createdAt": "2024-01-01T00:00:00Z"
    }
  }
}

Error Handling

The API uses standard HTTP status codes and returns detailed error messages.

Common Error Codes

Error Response Format

{
  "errors": [
    {
      "message": "Insufficient credits for this operation",
      "extensions": {
        "code": "INSUFFICIENT_CREDITS",
        "creditsRequired": 100,
        "creditsAvailable": 50
      }
    }
  ]
}

Webhooks

Receive real-time notifications when your text to video generation is complete.

Setting Up Webhooks

Include a <code>webhookUrl</code> parameter in your request to receive a POST notification when processing is complete.

Webhook Payload

{
  "id": "abc123xyz",
  "status": "completed",
  "url": "https://cdn.doitong.com/outputs/abc123xyz.mp4",
  "service": "wan",
  "createdAt": "2024-01-01T00:00:00Z",
  "completedAt": "2024-01-01T00:01:00Z",
  "metadata": {
    "duration": 5,
    "width": 1920,
    "height": 1080
  }
}

Webhook Security

All webhook requests include a signature header for verification:

X-Doitong-Signature: sha256=abc123...

Rate Limits

To ensure fair usage and system stability, the following rate limits apply:

Best Practices

1. Optimize Your Prompts

Write clear, descriptive prompts for best results:

• Be specific about visual elements, style, and mood
• Include details about lighting, camera angles, and composition
• Avoid contradictory or impossible requests

2. Handle Async Processing

Generation is asynchronous. Implement proper polling or webhooks:

// Polling example
async function pollStatus(jobId) {
  let status = 'processing';
  while (status === 'processing') {
    await sleep(2000); // Wait 2 seconds
    const result = await checkJobStatus(jobId);
    status = result.status;
  }
  return result;
}

3. Error Recovery

Implement retry logic with exponential backoff:

async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await sleep(Math.pow(2, i) * 1000);
    }
  }
}

4. Monitor Credit Usage

Track your credit consumption to avoid interruptions:

• Check credit balance before large batch operations
• Set up alerts for low credit thresholds
• Implement credit-aware request queuing
