Dilysu

I gael mynediad i Stable Diffusion drwy API Doitong, defnyddiwch eich allwedd API Doitong. Cynhwyswch hi ym mhennynnau'r mwtaniad GraphQL neu'r REST API.

Prisio

Mae Stable Diffusion API yn defnyddio model prisio sy'n seiliedig ar gredydau. Defnyddir credydau yn ôl cymhlethdod a hyd y cynnwys a gynhyrchir.

Pwyntiau Terfyn API

Mae Stable Diffusion API ar gael drwy ein pwynt terfyn GraphQL unedig.

Pwynt Terfyn GraphQL

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

Pwynt Terfyn REST

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

Paramedrau

Paramedrau sydd ar gael ar gyfer ceisiadau Stable Diffusion API:

Fformat yr Ymateb

Mae holl ymatebion yr API yn dilyn fformat cyson:

Ymateb Llwyddiannus

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

Ymateb Wedi'i Gwblhau

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

Trin Gwallau

Mae'r API yn defnyddio codau statws HTTP safonol ac yn dychwelyd negeseuon gwall manwl.

Codau Gwall Cyffredin

Fformat Ymateb Gwall

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

Webhooks

Derbyniwch hysbysiadau amser-real pan fydd eich text to image wedi'i gynhyrchu.

Ffurfweddu Webhooks

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

Llwyth Cyflog Webhook

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

Diogelwch Webhook

Mae pob cais webhook yn cynnwys pennyn llofnod ar gyfer dilysu:

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

Terfynau Cyfradd

Er mwyn sicrhau defnydd teg a sefydlogrwydd y system, mae'r terfynau cyfradd canlynol yn berthnasol:

Arferion Gorau

1. Optimeiddio eich Anogwyr

Ysgrifennwch anogwyr clir a disgrifiadol i gael y canlyniadau gorau:

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

2. Trin Prosesu Anghydamserol

Mae'r broses gynhyrchu yn anghydamserol. Gweithredwch brosesau 'polling' neu webhooks priodol:

// 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. Adfer o Wallau

Gweithredwch resymeg ailgeisio gydag egwyl esbonyddol (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. Monitro Defnydd Credydau

Traciwch eich defnydd o gredydau er mwyn osgoi toriadau yn y gwasanaeth:

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