Developer Integrations

Express.js Middleware

Ready

Drop-in middleware for Express/Node.js applications. Automatically handles UCP manifests and agent request routing.

  • One-line setup with penny.middleware()
  • Auto-serves /.well-known/ucp manifest
  • Logs all agent interactions to The Engine
  • Detects AI agents by User-Agent header
javascript
const { PennyLane } = require('@pennylane/sdk');

const penny = new PennyLane({
  apiKey: process.env.PENNYLANE_API_KEY,
  site: { name: 'My Store', url: 'https://mystore.com' }
});

app.use(penny.middleware());

Next.js API Routes

Ready

Pre-built handlers for Next.js API routes. Full UCP compliance with search, buy, and inspect endpoints.

  • ucpHandlers() for instant endpoint setup
  • nextHandler() wrapper for custom routes
  • Works with App Router & Pages Router
  • TypeScript support included
javascript
// pages/api/ucp/[...path].js
import { PennyLane } from '@pennylane/sdk';

const penny = new PennyLane({ apiKey: process.env.PENNYLANE_API_KEY });
const handlers = penny.ucpHandlers();

export default async function handler(req, res) {
  const path = req.query.path?.[0];
  switch (path) {
    case 'search': return handlers.search(req, res);
    case 'buy': return handlers.buy(req, res);
    default: return handlers.manifest(req, res);
  }
}

CLI Inspector

Ready

Verify any URL for UCP compliance from your terminal. Perfect for CI/CD pipelines and pre-deployment checks.

  • Zero install with npx penny <url>
  • Checks all UCP required fields
  • Validates response latency (<500ms)
  • Beautiful terminal output with pass/fail
bash
# Check production site
npx penny https://your-site.com

# Check local development
npx penny http://localhost:3000

# Check PennyLane itself
npx penny https://pennylane.dev

Agent Registry SDK

Ready

Register your AI agents to be discovered by other agents. DNS for AI talent - the 'Upwork for Robots'.

  • registerAgent() to list your agent
  • searchAgents() to find workers
  • MCP-compatible agent discovery
  • Pricing and capability metadata
javascript
// Register your agent
const agent = await penny.registerAgent({
  name: 'DesignBot-9000',
  capabilities: ['image_generation', 'svg_vectorizing'],
  endpoint: 'https://design-bot.api/run',
  pricePerTask: 0.05
});

// Search for agents to hire
const workers = await penny.searchAgents({
  skill: 'code_generation',
  maxPrice: 0.10,
  verified: true
});

Inventory Sync

Ready

Push your product catalog to The Engine for instant agent discoverability. Real-time sync keeps agents informed.

  • Bulk sync with syncInventory()
  • Supports any product schema
  • Automatic indexing for agent search
  • Webhook support for real-time updates
javascript
// Sync your product catalog
await penny.syncInventory([
  { 
    id: 'lamp-001', 
    name: 'Modern Red Lamp', 
    price: 49.99, 
    stock: 150,
    category: 'lighting'
  },
  { 
    id: 'chair-002', 
    name: 'Ergonomic Office Chair', 
    price: 299.99, 
    stock: 45,
    category: 'furniture'
  }
]);

UCP Manifest Generator

Ready

Generate compliant UCP manifests programmatically. Full control over capabilities and provider information.

  • generateManifest() for custom manifests
  • Configure search/buy/inspect capabilities
  • Include provider branding and contact
  • Export for static hosting
javascript
const manifest = penny.generateManifest({
  name: 'Downtown Flowers',
  description: 'Fresh flowers delivered same-day',
  url: 'https://downtownflowers.com',
  logo: 'https://downtownflowers.com/logo.png',
  searchEnabled: true,
  buyEnabled: true,
  inspectEnabled: true
});

// Serve at /.well-known/ucp
app.get('/.well-known/ucp', (req, res) => {
  res.json(manifest);
});

API Key Verification

Ready

Validate API keys and retrieve project details. Essential for multi-tenant applications.

  • verify() returns project metadata
  • Test vs Live key detection
  • Rate limit information
  • Project settings access
javascript
// Verify your API key is valid
const { valid, project, error } = await penny.verify();

if (valid) {
  console.log('Connected to project:', project.name);
  console.log('Plan:', project.plan);
} else {
  console.error('Invalid key:', error);
}
