What Does This SDK Do?

The AI Control Plane SDK provides:

1. Secure API Key Authentication: All operations are authenticated with your API key
2. Automatic Performance Tracking: Monitors API latency and success/failure rates
3. Intelligent Runtime Configuration: Receives AI-driven decisions for caching, circuit breaking, and more
4. Tenant ID Generation: Creates unique identifiers for multi-tenant applications
5. Express Middleware: Easy integration with Express.js applications
6. Manual Tracking: Flexible API for custom tracking scenarios

The SDK sends performance metrics to the AI Control Plane, which analyzes patterns and returns intelligent configuration decisions to optimize your service automatically.

Quick Start (5 minutes)

0. Get Your API Key

⚠️ IMPORTANT: API key authentication is now required for all SDK operations.

1. Sign up at your Control Plane dashboard (e.g., http://localhost:3000)
2. Navigate to API Keys page
3. Click "Generate New Key"
4. Copy your API key

1. Initialize SDK with API Key

import ControlPlaneSDK from "@ayushsoni12/ai-control-plane-sdk";

const controlPlane = new ControlPlaneSDK({
  apiKey: process.env.CONTROL_PLANE_API_KEY, // ⚠️ REQUIRED
  serviceName: "my-service",
  controlPlaneUrl: "http://localhost:8000",
  tenantId: generateTenantId("user"), // Optional: for multi-tenancy
});

Best Practice: Store your API key in environment variables:

# .env file
CONTROL_PLANE_API_KEY=your-api-key-here
CONTROL_PLANE_URL=http://localhost:8000

import dotenv from "dotenv";
dotenv.config();

const controlPlane = new ControlPlaneSDK({
  apiKey: process.env.CONTROL_PLANE_API_KEY,
  serviceName: "my-service",
  controlPlaneUrl: process.env.CONTROL_PLANE_URL,
});

2. Use Middleware (Automatic Tracking)

Real Example from Demo Service:

import express from "express";
import ControlPlaneSDK, {
  generateTenantId,
} from "@ayushsoni12/ai-control-plane-sdk";
import dotenv from "dotenv";

dotenv.config();

const app = express();
const controlPlane = new ControlPlaneSDK({
  apiKey: process.env.CONTROL_PLANE_API_KEY, // Required
  serviceName: "demo-service",
  controlPlaneUrl: process.env.CONTROL_PLANE_URL || "http://localhost:8000",
  tenantId: generateTenantId("user"),
});

// Example: Product API with automatic tracking
app.get(
  "/products/:id?",
  controlPlane.middleware("/products"),
  async (req, res) => {
    const { id } = req.params;

    // Simulate database delay
    await new Promise((resolve) => setTimeout(resolve, 100));

    if (id) {
      // Get single product
      const product = { id: parseInt(id), name: "Laptop", price: 999 };
      res.json({ product });
    } else {
      // Get all products
      const products = [
        { id: 1, name: "Laptop", price: 999 },
        { id: 2, name: "Phone", price: 699 },
      ];
      res.json({ products });
    }
  },
);

app.listen(3001, () => {
  console.log("Server running on http://localhost:3001");
});

What happens automatically:

• ✅ Tracks request latency
• ✅ Tracks success/failure status
• ✅ Sends metrics to Control Plane with API key authentication
• ✅ Receives runtime configuration (caching, circuit breaker decisions)
• ✅ Makes config available in req.controlPlane

3. Manual Tracking (Without Middleware)

app.post("/login", async (req, res) => {
  const start = Date.now();

  try {
    // Get config from Control Plane
    const config = await controlPlane.getConfig("/login");

    // Your business logic
    const result = await authenticate(req.body);

    // Track successful request (API key sent automatically)
    await controlPlane.track("/login", Date.now() - start, "success");

    res.json(result);
  } catch (error) {
    // Track failed request
    await controlPlane.track("/login", Date.now() - start, "error");
    res.status(500).json({ error: "Login failed" });
  }
});






## API Authentication

### Overview

All SDK operations require API key authentication. The SDK automatically includes your API key in the `Authorization` header for all requests to the Control Plane.

### Getting an API Key

1. Sign up at your Control Plane dashboard
2. Navigate to the **API Keys** page
3. Click **"Generate New Key"**
4. Copy and securely store your API key

### Authentication Flow

```
SDK Request → Authorization: Bearer <api_key> → Control Plane
                                                      ↓
                                                 Validates Key
                                                      ↓
                                              Associates with User
                                                      ↓
                                               Stores Signal
```

### Error Handling

The SDK handles authentication errors gracefully:

**Missing API Key:**
```javascript
// ⚠️ Warning logged to console
const controlPlane = new ControlPlaneSDK({
  serviceName: "my-service"
});
// Console: [ControlPlane] ⚠️ No API key provided. Please initialize the SDK with an API key.
```

**Invalid API Key:**
- Requests will fail silently (SDK doesn't crash your service)
- Errors logged to console
- Signals won't be tracked

**Best Practices:**

1. **Use Environment Variables**
   ```javascript
   apiKey: process.env.CONTROL_PLANE_API_KEY
   ```

2. **Never Commit API Keys**
   - Add `.env` to `.gitignore`
   - Use `.env.example` for documentation

3. **Rotate Keys Regularly**
   - Generate new keys periodically
   - Delete old keys from dashboard

4. **Monitor Key Usage**
   - Check "Last Used" timestamp in dashboard
   - Deactivate unused keys

## API Reference

### `track(endpoint, latencyMs, status)`

Send performance signal to control plane.

**Parameters:**

- `endpoint` (string) - API endpoint (e.g., '/products')
- `latencyMs` (number) - Request latency in milliseconds
- `status` (string) - 'success' or 'error'

**Example:**

```javascript
await controlPlane.track("/api/users", 245, "success");

getConfig(endpoint)

Get runtime configuration from control plane.

Returns:

{
  cache_enabled: true/false,
  circuit_breaker: true/false,
  reason: "explanation"
}

Example:

const config = await controlPlane.getConfig("/products");
if (config.cache_enabled) {
  // Use cache
}

middleware(endpoint)

Express middleware for automatic tracking.

Example:

app.get("/products", controlPlane.middleware("/products"), (req, res) => {
  // Config available in req.controlPlane
});

Use Cases

Automatic Caching

app.get("/products", controlPlane.middleware("/products"), async (req, res) => {
  // Check cache
  if (req.controlPlane.shouldCache && cache.products) {
    return res.json(cache.products);
  }

  // Fetch from database
  const products = await db.getProducts();

  // Cache if enabled
  if (req.controlPlane.shouldCache) {
    cache.products = products;
  }

  res.json(products);
});

Circuit Breaker

app.get(
  "/external-api",
  controlPlane.middleware("/external-api"),
  async (req, res) => {
    // Skip if circuit breaker active
    if (req.controlPlane.shouldSkip) {
      return res.json({ data: cachedData || [] });
    }

    // Call external API
    const data = await externalAPI.getData();
    res.json(data);
  },
);
