+
+## Overview
+
+The TaaS Platform provides SDKs for multiple programming languages to simplify integration with platform services:
+
+| Language | Package | Status |
+|----------|---------|--------|
+| Go | `github.com/nutcas3/telecom-platform/sdk/go` | ✅ Stable |
+| Python | `telecom-sdk` | ✅ Stable |
+| TypeScript | `@taas/sdk` | ✅ Stable |
+| Kotlin | `com.taas:sdk` | 🚧 Beta |
+| Ruby | `taas-sdk` | 🚧 Beta |
+| Swift | `TaaSSDK` | 🚧 Beta |
+| Rust | `taas-sdk` | 🚧 Beta |
+| Elixir | `taas_sdk` | 🚧 Beta |
+
+---
+
+## Installation
+
+### Go
+
+```bash
+go get github.com/nutcas3/telecom-platform/sdk/go
+```
+
+### Python
+
+```bash
+pip install telecom-sdk
+```
+
+### TypeScript/JavaScript
+
+```bash
+npm install @taas/sdk
+# or
+pnpm add @taas/sdk
+```
+
+---
+
+## Authentication
+
+All SDKs use JWT-based authentication. Obtain an API key from the dashboard or use username/password authentication.
+
+### API Key Authentication
+
+```go
+// Go
+client := taas.NewClient(taas.WithAPIKey("your-api-key"))
+```
+
+```python
+# Python
+from telecom_sdk import TelecomClient
+client = TelecomClient(api_key="your-api-key")
+```
+
+```typescript
+// TypeScript
+import { TelecomClient } from '@taas/sdk';
+const client = new TelecomClient({ apiKey: 'your-api-key' });
+```
+
+---
+
+## Go SDK
+
+### Basic Usage
+
+```go
+package main
+
+import (
+    "context"
+    "fmt"
+    "log"
+
+    taas "github.com/nutcas3/telecom-platform/sdk/go"
+)
+
+func main() {
+    // Initialize client
+    client := taas.NewClient(
+        taas.WithBaseURL("https://api.telecom.com"),
+        taas.WithAPIKey("your-api-key"),
+    )
+
+    // Create a subscriber
+    subscriber, err := client.Subscribers.Create(context.Background(), &taas.CreateSubscriberRequest{
+        MSISDN:    "+1234567890",
+        FirstName: "John",
+        LastName:  "Doe",
+        Email:     "[email protected]",
+        PlanID:    1,
+    })
+    if err != nil {
+        log.Fatal(err)
+    }
+    fmt.Printf("Created subscriber: %s\n", subscriber.ID)
+}
+```
+
+### Analytics API
+
+```go
+// Churn Prediction
+analyticsAPI := taas.NewAnalyticsAPI(client.HTTPClient)
+
+// Predict churn for a profile
+prediction, err := analyticsAPI.PredictChurn(ctx, "profile-123")
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Churn Risk: %s (Score: %.2f)\n", prediction.RiskLevel, prediction.RiskScore)
+
+// Get churn metrics
+metrics, err := analyticsAPI.GetChurnMetrics(ctx, "monthly")
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Monthly Churn Rate: %.2f%%\n", metrics.MonthlyChurnRate)
+
+// Get at-risk customers
+atRisk, err := analyticsAPI.GetAtRiskCustomers(ctx, taas.ChurnRiskHigh, 100)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Found %d high-risk customers\n", len(atRisk))
+
+// Market metrics
+marketMetrics, err := analyticsAPI.GetMarketMetrics(ctx, "quarterly")
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Market Share: %.2f%%\n", marketMetrics.MarketShare)
+```
+
+### Security API
+
+```go
+// Fraud Detection
+securityAPI := taas.NewSecurityAPI(client.HTTPClient)
+
+// Analyze a transaction
+alert, err := securityAPI.AnalyzeTransaction(ctx, map[string]interface{}{
+    "profile_id":  "profile-123",
+    "amount":      99.99,
+    "ip_address":  "192.168.1.1",
+    "device_id":   "device-456",
+    "transaction": "payment",
+})
+if err != nil {
+    log.Fatal(err)
+}
+if alert != nil {
+    fmt.Printf("Fraud Alert: %s (Severity: %s)\n", alert.Type, alert.Severity)
+}
+
+// Get fraud alerts
+alerts, err := securityAPI.GetFraudAlerts(ctx, taas.FraudAlertFilter{
+    Severity: taas.FraudSeverityHigh,
+    Status:   "new",
+    Limit:    50,
+})
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Found %d fraud alerts\n", len(alerts))
+
+// Get fraud metrics
+fraudMetrics, err := securityAPI.GetFraudMetrics(ctx, "monthly")
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Resolution Rate: %.2f%%\n", fraudMetrics.ResolutionRate)
+```
+
+---
+
+## Python SDK
+
+### Basic Usage
+
+```python
+from telecom_sdk import TelecomClient
+from telecom_sdk.types import CreateSubscriberRequest
+
+# Initialize client
+client = TelecomClient(
+    base_url="https://api.telecom.com",
+    api_key="your-api-key"
+)
+
+# Create a subscriber
+subscriber = client.subscribers.create(CreateSubscriberRequest(
+    msisdn="+1234567890",
+    first_name="John",
+    last_name="Doe",
+    email="[email protected]",
+    plan_id=1
+))
+print(f"Created subscriber: {subscriber.id}")
+```
+
+### Analytics API
+
+```python
+from telecom_sdk import TelecomClient
+from telecom_sdk.types import ChurnRiskLevel
+
+client = TelecomClient(api_key="your-api-key")
+
+# Churn Prediction
+prediction = client.analytics.predict_churn("profile-123")
+print(f"Churn Risk: {prediction.risk_level} (Score: {prediction.risk_score:.2f})")

+  lastName: 'Doe',
+  email: '[email protected]',
+  planId: 1
+});
+console.log(`Created subscriber: ${subscriber.id}`);
+```
+

+### Example: Currency Conversion
+
+```typescript
+// TypeScript
+const result = await client.currency.convert({
+  from: 'USD',
+  to: 'EUR',
+  amount: 100.00
+});
+console.log(`${result.amount} ${result.to} = ${result.converted} ${result.from}`);
+```
+
+```python
+# Python
+result = client.currency.convert(
+    from_currency="USD",
+    to_currency="EUR",
+    amount=100.00
+)
+print(f"{result.amount} {result.to_currency} = {result.converted} {result.from_currency}")
+```
+
+```go
+// Go
+result, err := client.Currency.Convert(ctx, &taas.ConvertRequest{
+    From:   "USD",
+    To:     "EUR",
+    Amount: 100.00,
+})
+fmt.Printf("%f %s = %f %s\n", result.Amount, result.To, result.Converted, result.From)
+```
+
+---
+
+## Error Handling
+
+All SDKs provide consistent error handling:
+
+### Go
+
+```go
+subscriber, err := client.Subscribers.Get(ctx, "invalid-id")
+if err != nil {
+    if apiErr, ok := err.(*taas.APIError); ok {
+        fmt.Printf("API Error: %s (Code: %d)\n", apiErr.Message, apiErr.StatusCode)
+    } else {
+        fmt.Printf("Network Error: %v\n", err)
+    }
+}
+```
+
+### Python
+
+```python
+from telecom_sdk.exceptions import APIError, NetworkError
+
+try:
+    subscriber = client.subscribers.get("invalid-id")
+except APIError as e:
+    print(f"API Error: {e.message} (Code: {e.status_code})")
+except NetworkError as e:
+    print(f"Network Error: {e}")
+```
+
+### TypeScript
+
+```typescript
+import { APIError, NetworkError } from '@taas/sdk';
+
+try {
+  const subscriber = await client.subscribers.get('invalid-id');
+} catch (error) {
+  if (error instanceof APIError) {
+    console.log(`API Error: ${error.message} (Code: ${error.statusCode})`);
+  } else if (error instanceof NetworkError) {
+    console.log(`Network Error: ${error.message}`);
+  }
+}
+```
+
+---
+
+## Rate Limiting
+
+The API enforces rate limits per user:
+- **Default**: 100 requests per minute
+- **Burst**: Up to 200 requests in short bursts
+
+SDKs automatically handle rate limiting with exponential backoff:
+
+```typescript
+const client = new TelecomClient({
+  apiKey: 'your-api-key',
+  retryConfig: {
+    maxRetries: 3,
+    retryDelay: 1000, // 1 second
+    retryOnRateLimit: true
+  }
+});
+```
+
+---
