-RATE LIMIT STRATEGIES (استراتژی‌های محدودیت):
-───────────────────────────────────────────────
-
-1. کش کردن (Caching):
-   - ذخیره نتایج برای 1-5 دقیقه
-   - استفاده از localStorage برای کش مرورگر
-
-2. چرخش کلید (Key Rotation):
-   - استفاده از چندین کلید API
-   - تعویض خودکار در صورت محدودیت
-
-3. Fallback Chain:
-   - Primary → Fallback1 → Fallback2
-   - تا 5-10 جایگزین برای هر سرویس
-
-4. Request Queuing:
-   - صف بندی درخواست‌ها
-   - تاخیر بین درخواست‌ها
-
-5. Multi-Source Aggregation:
-   - دریافت از چند منبع همزمان
-   - میانگین گیری نتایج
-
-
-ERROR HANDLING (مدیریت خطا):
-──────────────────────────────
-
-try {
-  const data = await api.fetchWithFallback(primary, fallbacks, endpoint, params);
-} catch (error) {
-  if (error.message.includes('rate limit')) {
-    // Switch to fallback
-  } else if (error.message.includes('CORS')) {
-    // Use CORS proxy
-  } else {
-    // Show error to user
-  }
-}
-
-
-DEPLOYMENT TIPS (نکات استقرار):
-─────────────────────────────────
-
-1. Backend Proxy (توصیه می‌شود):
-   - Node.js/Express proxy server
-   - Cloudflare Worker
-   - Vercel Serverless Function
-
-2. Environment Variables:
-   - ذخیره کلیدها در .env
-   - عدم نمایش در کد فرانت‌اند
-
-3. Rate Limiting:
-   - محدودسازی درخواست کاربر
-   - استفاده از Redis برای کنترل
-
-4. Monitoring:
-   - لاگ گرفتن از خطاها
-   - ردیابی استفاده از API

+RATE LIMIT STRATEGIES (استراتژی‌های محدودیت):
+───────────────────────────────────────────────
+
+1. کش کردن (Caching):
+   - ذخیره نتایج برای 1-5 دقیقه
+   - استفاده از localStorage برای کش مرورگر
+
+2. چرخش کلید (Key Rotation):
+   - استفاده از چندین کلید API
+   - تعویض خودکار در صورت محدودیت
+
+3. Fallback Chain:
+   - Primary → Fallback1 → Fallback2
+   - تا 5-10 جایگزین برای هر سرویس
+
+4. Request Queuing:
+   - صف بندی درخواست‌ها
+   - تاخیر بین درخواست‌ها
+
+5. Multi-Source Aggregation:
+   - دریافت از چند منبع همزمان
+   - میانگین گیری نتایج
+
+
+ERROR HANDLING (مدیریت خطا):
+──────────────────────────────
+
+try {
+  const data = await api.fetchWithFallback(primary, fallbacks, endpoint, params);
+} catch (error) {
+  if (error.message.includes('rate limit')) {

+}
+
+
+DEPLOYMENT TIPS (نکات استقرار):
+─────────────────────────────────
+
+1. Backend Proxy (توصیه می‌شود):
+   - Node.js/Express proxy server
+   - Cloudflare Worker
+   - Vercel Serverless Function
+
+2. Environment Variables:
+   - ذخیره کلیدها در .env
+   - عدم نمایش در کد فرانت‌اند
+
+3. Rate Limiting:
+   - محدودسازی درخواست کاربر
+   - استفاده از Redis برای کنترل
+
+4. Monitoring:
+   - لاگ گرفتن از خطاها
+   - ردیابی استفاده از API

+   - تست منظم fallbackها
+
+3. 💾 Cache responses when possible
+   - صرفه‌جویی در استفاده از API
+   - سرعت بیشتر برای کاربر
+
+4. 📊 Monitor API usage
+   - ردیابی تعداد درخواست‌ها
+   - هشدار قبل از رسیدن به محدودیت
+
+5. 🔐 Secure your endpoints
+   - محدودسازی domain
+   - استفاده از CORS headers

+
+6. 🌐 Test with and without CORS proxies

+   - استفاده از پروکسی فقط در صورت نیاز
+
+7. 📱 Mobile-friendly implementations
+   - بهینه‌سازی برای شبکه‌های ضعیف
+   - کاهش اندازه درخواست‌ها
