Priser

Luma Labs API bruger en kreditbaseret prismodel. Forbruget af kreditter afhænger af det genererede indholds kompleksitet og varighed.

API-endpoints

Luma Labs API er tilgængelig via vores forenede GraphQL-endpoint.

GraphQL-endpoint

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

REST-endpoint

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

Parametre

Tilgængelige parametre for Luma Labs API-anmodninger:

Svarsformat

Alle API-svar følger et fast format:

Succes-svar

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

Gennemført-svar

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

Fejlhåndtering

API'en bruger standard HTTP-statuskoder og returnerer detaljerede fejlmeddelelser.

Almindelige fejlkoder

Format for fejlsvar

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

Webhooks

Modtag notifikationer i realtid, når din text to video-generering er færdig.

Opsætning af 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": "luma",
  "createdAt": "2024-01-01T00:00:00Z",
  "completedAt": "2024-01-01T00:01:00Z",
  "metadata": {
    "duration": 5,
    "width": 1920,
    "height": 1080
  }
}

Webhook-sikkerhed

Alle webhook-anmodninger inkluderer en signatur-header til verificering:

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

Rate limits

For at sikre fair brug og systemstabilitet gælder følgende hastighedsbegrænsninger:

Best practices

1. Optimer dine prompts

Skriv klare og beskrivende prompts for at få de bedste resultater:

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

2. Håndter asynkron behandling

Genereringen er asynkron. Implementer korrekt polling eller 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. Fejlhåndtering og recovery

Implementer retry-logik med eksponentiel 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. Overvåg kreditforbrug

Hold øje med dit forbrug af kreditter for at undgå afbrydelser:

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