A phone runs an agent chat app. The user asks the agent to order coffee from Starbucks. The agent asks for a $10.00 budget, the user approves it on a Mastercard, and the agent starts the order on starbucks.com.

Give your AI agent a safe way to pay. Your users save a card once. When the agent must pay, it asks for a budget with an amount, a store and an expiry date. The user approves the budget on a screen that you host. Then the agent buys on any website with Crossmint Agent Checkouts. This open source demo shows the full flow in a chat app, in messaging apps, in MCP hosts and in a terminal.

Key features

Save cards in the Crossmint PCI vault. Card data never touches your servers.
Let agents ask for a budget with an amount, a store and an expiry date. Users approve it one time.
Visa Intelligent Commerce and Mastercard Agent Pay enforce each limit on the card network. Users keep their points and rewards.
Buy on any website with one API call: products, restaurant tables, flights and event tickets. It works with UCP and with any browser checkout.
Sign in to stores safely. The user types the password one time. The password is encrypted, only that store uses it, and the agent never sees it.
Save buyer details (name, contact and shipping address), so checkouts do not stop to ask for them.
Use the same APIs in your own app, in iMessage, WhatsApp and Instagram, in MCP hosts such as Claude, ChatGPT and Cursor, and in terminal agents.
Add the full flow to your own app with one prompt in Claude Code, Cursor or Codex.
