Prìsean

Tha Runway Gen4 API a' cleachdadh modail prìse stèidhichte air creideasan. Thèid creideasan a chleachdadh a rèir cho iomadh-fhillte 's a tha an t-susbaint agus dè cho fada 's a mhaireas i.

Puingean-crìche API

Tha Runway Gen4 API ri fhaighinn tron phuing-chrìche GraphQL aonaichte againn.

Puing-chrìche GraphQL

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

Puing-chrìche REST

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

Paramaidirean

Paramaidirean a tha rim faighinn airson iarrtasan Runway Gen4 API:

Cruth na Freagairt

Tha a h-uile freagairt API a' leantainn cruth cunbhalach:

Freagairt Shoirbheachail

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

Freagairt Chrìochnaichte

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

Làimhseachadh Mhearachdan

Tha an API a' cleachdadh còdan inbhe HTTP àbhaisteach agus a' tilleadh teachdaireachdan mearachd mionaideach.

Còdan Mearachd Cumanta

Cruth Freagairt Mearachd

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

Webhooks

Faigh fiosan fìor-ùine nuair a bhios cruthachadh text to video deiseil.

A' rèiteachadh Webhooks

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

Payload Webhook

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

Tèarainteachd Webhook

Tha bann-cinn ainm-sgrìobhte anns a h-uile iarrtas webhook airson dearbhadh:

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

Crìochan Luaths

Gus dèanamh cinnteach gu bheil an siostam cothromach agus seasmhach, tha na crìochan luaths seo an sàs:

Na Cleachdaidhean as Fheàrr

1. Optimaisich na Brosnachaidhean agad

Sgrìobh brosnachaidhean soilleir, tuairisgeulach airson na toraidhean as fheàrr:

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

2. Làimhsich Pròiseasadh Neo-shioncronach

Tha an cruthachadh neo-shioncronach. Cuir an sàs dòigh sgrùdaidh (polling) no 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. Ath-shlànachadh Mhearachdan

Cuir an sàs loidsig ath-fheuchainn le dàil eas-chruthach (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. Cum sùil air Cleachdadh Chreideasan

Cum sùil air na creideasan a chleachdas tu gus nach bi briseadh sam bith ann:

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