What can an AI agent do
when it can pay?

37 MCP servers. 4 agentic payment protocols. 14 Brazilian rails. Every tool an AI agent needs to operate commerce — from checkout to settlement.

Stripe ACP

Agent Checkout

AI agent browses products and completes purchases

Your agent browses a merchant catalog, adds items to cart, and completes checkout — all via MCP tools. Inline payment inside the chat, no redirects. Works with 1M+ Shopify merchants via ACP.

API Micropayments

Agent pays $0.001 per API call with USDC

When your agent hits a premium API and receives HTTP 402, it automatically signs a USDC payment on Base and retries. Machine-to-machine commerce at the HTTP layer. Tested on-chain with real USDC transfers.
