Flux Krea Optimized API

Optimiséiert Flux-Implementéierung mat verschiddene Qualitéitsstufen.

Authentifizéierung

Fir op Flux Krea iwwer d'Doitong API zouzegräifen, benotzt Ären Doitong API-Schlëssel. Füügt dësen an d'GraphQL Mutation oder an d'REST API Headers bäi.

// GraphQL Header
{
  "Authorization": "Bearer YOUR_API_KEY"
}

// REST Header
"X-API-Key": "YOUR_API_KEY"

Präisser

Flux Krea API benotzt e Credit-baséierte Präismodell. Credits ginn ofhängeg vun der Komplexitéit an der Dauer vum generéierten Inhalt ofgerechent.

API-Endpunkten

Flux Krea API ass iwwer eisen eenheetleche GraphQL-Endpunkt verfügbar.

GraphQL-Endpunkt

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

REST-Endpunkt

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

Parameteren

Verfügbar Parameter fir Flux Krea API Ufroen:

Äntwert-Format

All API-Äntwerte folgen engem eenheetleche Format:

Erfollegräich Äntwert

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

Ofgeschloss Äntwert

{
  "data": {
    "generateimage": {
      "id": "abc123xyz",
      "status": "completed",

Feeler-Äntwert-Format

{
  "errors": [
    {
      "message": "Insufficient credits for this operation",
      "extensions": {
        "code": "INSUFFICIENT_CREDITS",

Webhook-Payload

{
  "id": "abc123xyz",
  "status": "completed",
  "url": "https://cdn.doitong.com/outputs/abc123xyz.jpg",
  "service": "flux-krea",
  "createdAt": "2024-01-01T00:00:00Z",

Webhook-Sécherheet

All Webhook-Ufroe enthalen e Signature-Header fir d'Verifikatioun:

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

Rate Limits

Fir eng fair Notzung an d'Systemstabilitéit ze garantéieren, gëllen dës Limitten:

Best Practices

1. Optimiséiert Är Prompts

Schreift kloer an detailléiert Prompts fir déi bescht Resultater:

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

2. Asynchron Veraarbechtung handhaben

D'Generéierung ass asynchron. Implementéiert e richtegt Polling oder 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. Feelerbehandlung

Implementéiert eng Retry-Logik mat exponentiellem 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. Credit-Verbrauch iwwerwaachen

Verfollegt Äre Credit-Verbrauch fir Ënnerbriechungen ze vermeiden:

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