  const response = await fetch(`${BASE_URL}/flux/dev`, {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({

  const response = await fetch(`${BASE_URL}/ideogram/v3-character-edit`, {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${API_KEY}`,
      'Content-Type': 'application/json'

Advanced Client Class

class FiremoonStudio {
  constructor(apiKey, baseUrl = 'https://firemoon.studio/api/v1') {
    this.apiKey = apiKey;
    this.baseUrl = baseUrl;
  }

  async request(endpoint, params) {
    const response = await fetch(`${this.baseUrl}${endpoint}`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${this.apiKey}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(params)
    });

    if (!response.ok) {
      const error = await response.json();
      throw new Error(`API Error: ${error.message}`);
    }

    return await response.json();
  }

  // Image generation methods
  async generateImage(provider, model, params) {
    return this.request(`/${provider}/${model}`, params);
  }

  // Convenience methods
  async fluxDev(prompt, options = {}) {
    return this.generateImage('flux', 'dev', {
      prompt,
      num_images: 1,
      image_size: 'landscape_4_3',
      guidance_scale: 3.5,
      ...options
    });
  }

  async klingVideo(prompt, options = {}) {
    return this.generateImage('kling', 'kling-2-1-master', {
      prompt,
      duration: '5',
      aspect_ratio: '16:9',
      ...options
    });
  }

  async ideogramEdit(prompt, imageUrl, options = {}) {
    return this.generateImage('ideogram', 'v3-character-edit', {
      prompt,
      image_url: imageUrl,
      style: 'realistic',
      ...options
    });
  }
}

// Usage
const client = new FiremoonStudio(process.env.FIREMOON_API_KEY);

// Generate multiple images
const images = await client.fluxDev('A futuristic city', { num_images: 3 });
images.images.forEach((img, i) => {
  console.log(`Image ${i + 1}:`, img.url);
});

// Generate video
const video = await client.klingVideo('A rocket launch');
console.log('Video:', video.videos[0].url);

Error Handling and Retries

class FiremoonAPIError extends Error {
  constructor(message, status, details) {
    super(message);
    this.name = 'FiremoonAPIError';
    this.status = status;
    this.details = details;
  }
}

async function requestWithRetry(endpoint, params, maxRetries = 3) {
  let lastError;

  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      const response = await fetch(`${BASE_URL}${endpoint}`, {
        method: 'POST',
        headers: {
          'Authorization': `Bearer ${API_KEY}`,
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(params)
      });

      if (response.status === 429) {
        // Rate limited - wait and retry
        const resetTime = response.headers.get('X-RateLimit-Reset');
        const waitTime = Math.min(1000 * Math.pow(2, attempt), 30000);
        console.log(`Rate limited. Waiting ${waitTime}ms before retry ${attempt}/${maxRetries}`);
        await new Promise(resolve => setTimeout(resolve, waitTime));
        continue;
      }

      if (!response.ok) {
        const error = await response.json();
        throw new FiremoonAPIError(error.message, response.status, error);
      }

      return await response.json();

    } catch (error) {
      lastError = error;

      // Don't retry on client errors (4xx except 429)
      if (error.status >= 400 && error.status < 500 && error.status !== 429) {
        break;
      }

      // Don't retry on last attempt
      if (attempt === maxRetries) {
        break;
      }

      console.log(`Attempt ${attempt} failed, retrying...`);
    }
  }

  throw lastError;
}

// Usage with error handling
async function safeGenerateImage(prompt) {
  try {
    return await requestWithRetry('/flux/dev', { prompt });
  } catch (error) {
    if (error instanceof FiremoonAPIError) {
      switch (error.status) {
        case 400:
          console.error('Invalid request:', error.details);
          break;
        case 401:
          console.error('Invalid API key');
          break;
        case 403:
          console.error('Access denied to this provider');
          break;
        default:
          console.error('API error:', error.message);
      }
    } else {
      console.error('Network error:', error.message);
    }
    throw error;
  }
}

Batch Processing

async function generateBatch(prompts, options = {}) {
  const batchSize = options.batchSize || 3; // Process in batches to avoid rate limits
  const results = [];
  const errors = [];

  for (let i = 0; i < prompts.length; i += batchSize) {
    const batch = prompts.slice(i, i + batchSize);

    const batchPromises = batch.map(async (prompt, index) => {
      try {
        const result = await requestWithRetry('/flux/dev', {
          prompt,
          num_images: 1,
          ...options
        });
        return { success: true, prompt, result, batchIndex: i + index };
      } catch (error) {
        errors.push({ prompt, error, batchIndex: i + index });
        return { success: false, prompt, error, batchIndex: i + index };
      }
    });

    const batchResults = await Promise.all(batchPromises);
    results.push(...batchResults);

    // Small delay between batches to be respectful
    if (i + batchSize < prompts.length) {
      await new Promise(resolve => setTimeout(resolve, 1000));
    }
  }

  return { results, errors };
}

// Usage
const prompts = [
  'A sunset over mountains',
  'A futuristic city',
  'A serene lake',
  'A space rocket launch',
  'A butterfly on a flower'
];

const { results, errors } = await generateBatch(prompts, {
  batchSize: 2,
  guidance_scale: 4.0
});

console.log(`Generated ${results.filter(r => r.success).length} images`);
if (errors.length > 0) {
  console.log(`Failed to generate ${errors.length} images`);
}

Rate Limit Monitoring

class RateLimitTracker {
  constructor() {
    this.requests = [];
    this.warnings = [];
  }

  trackRequest() {
    const now = Date.now();
    // Keep only requests from the last minute
    this.requests = this.requests.filter(time => now - time < 60000);
    this.requests.push(now);

    const requestsPerMinute = this.requests.length;

    if (requestsPerMinute > 45) { // 75% of 60 limit
      console.warn(`Approaching rate limit: ${requestsPerMinute}/60 requests/minute`);
      this.warnings.push({
        timestamp: now,
        requestsPerMinute,
        message: 'Approaching rate limit'
      });
    }
  }

  getStats() {
    const now = Date.now();
    const lastMinute = this.requests.filter(time => now - time < 60000);
    const lastHour = this.requests.filter(time => now - time < 3600000);

    return {
      lastMinute: lastMinute.length,
      lastHour: lastHour.length,
      warnings: this.warnings.slice(-10) // Last 10 warnings
    };
  }
}

// Usage
const tracker = new RateLimitTracker();

// Wrap your API calls
async function trackedRequest(endpoint, params) {
  tracker.trackRequest();
  return requestWithRetry(endpoint, params);
}

// Check stats periodically
setInterval(() => {
  const stats = tracker.getStats();
  if (stats.warnings.length > 0) {
    console.log('Rate limit warnings:', stats.warnings.length);
  }
}, 10000);
