This connects your agent to Coinbase's x402 micropayment protocol, which lets machines pay for HTTP requests with USDC on Base or Solana. When an API returns a 402 Payment Required, the agent automatically sends a few cents on-chain and retries the request. No checkout UI, no human approval. It's the lowest-friction payment layer in the agentic protocol stack: pure HTTP-native settlement for API calls, data access, or compute. Useful when you want agents to buy resources directly from other services without involving Stripe checkout flows or authorization layers like AP2. Part of the broader MCP Dev LATAM collection bridging traditional LATAM commerce APIs with emerging agentic payment rails.
