# Overview

> Payment infrastructure for AI agents

Enable agents to **pay for anything**, all under spending rules defined and controlled by your users. Integrate via a white-label SDK that plugs into your agent framework as a tool or skill without handling sensitive credentials and while being PCI-compliant.

Three products make it happen, each usable on its own and built to compose:

1. **Agent Cards:** a card for your agent to pay with, secured by Visa VIC and Mastercard Agent Pay.
2. **Agent Wallets:** a non-custodial wallet for stablecoin micropayments via x402 and MPP.
3. **Agent Checkouts:** one API to buy from any merchant. Supports any payment method the merchant supports, from Crossmint Agent Cards or any other agent card solution (e.g. Ramp Agent Cards), to saved cards in your account, Shop Pay, bank transfer, Bizum, etc.

## Payment methods
