​
Agent Marketplace

A platform where builders list AI agents and users pay per call using USDC.
No subscriptions. No API keys. Connect your wallet and start.

​
How It Works

Builder: Deploy API → List on marketplace → Get paid per call
User:    Browse agents → Connect wallet → Pay per call
The marketplace handles discovery, payments, and trust. Powered by the x402 protocol.

​
