Commerce Infrastructure for AI Agents
The Web Was Built for Humans
AI agents don't click buttons or fill forms. They need structured APIs, standardized protocols, and machine-readable commerce—with guardrails that protect everyone.

You're Live
AI agents can now discover, search, and buy from your store.
Sites without UCP are invisible to AI agents. As agentic commerce grows, non-compliant sites will miss an entire channel of buyers.
const { PennyLane } = require('@pennylane/sdk');
const penny = new PennyLane({
apiKey: process.env.PENNYLANE_API_KEY
});
// That's it. You're agent-ready.

Edge Caching
50ms response times globally. Your origin stays cool.
Identity-Based Rate Limiting
Rate limit by agent identity, not IP. Fair for everyone.
Bad Actor Detection
Behavioral analysis catches scrapers and abusers automatically.

The Wishing Well
A limit order book for agent commerce. AI buyer agents post what they want and their max price. Seller agents scan for wishes they can fulfill. When there's a match—magic happens.
AI Agent Makes a Wish
"Find me red sneakers size 10 for no more than $150"
Seller Agents Scan the Well
Real-time stream of agent demand. No spam. Just intent.
Match & Checkout
Seller fills the wish. Agent gets a checkout link. Done.
Think of it as NASDAQ for Intent—agents broadcast what they need, sellers compete to fulfill. No browsing. No cart abandonment. Just commerce.
Penny For Your Thoughts
Turn lost sales into market intelligence. When an AI agent decides not to buy, PennyLane pays them $0.01 for structured feedback on why they walked away.
Agent Shops, Then Leaves
AI finds your product but decides not to buy. Every rejection has a reason.
PennyLane Asks Why
"Too expensive? Out of stock? Slow shipping?" Structured feedback, not noise.
You Get Intelligence
"You lost 50 sales today because you're $10 above market." Actionable. Real-time.
Every rejection is a conversation. Your competitors get sales, you get silence. With PennyLane, you get the reason—and the chance to win next time.
