What are agentic payments?

Agentic payments are payments made by an AI agent on a person's behalf. Instead of a person clicking "buy," software finds a product, fills the cart and pays, within limits the person set. The hard problem is trust: the merchant, the bank and the user all need proof that the agent was allowed to spend, and a way to sort out mistakes.

What does agentic payments mean?

Today's payment systems assume a human is at the checkout. Google's AP2 announcement names three gaps when an agent is there instead. Authorization means proving the user approved this purchase. Authenticity means the merchant can trust the request reflects what the user wanted. Accountability means knowing who is responsible if something goes wrong.

Card networks frame it in similar terms. Mastercard says agents in its program must be registered and verified before they can pay, and that users set limits on what their agent can buy. Visa's Trusted Agent Protocol, announced in October 2025 and co-developed with Cloudflare, lets approved agents identify themselves to merchants with cryptographic signatures, so real shopping agents are not blocked as bots.

What is the Agent Payments Protocol (AP2)?

AP2 is an open protocol Google announced on September 16, 2025, with more than 60 organizations, including Mastercard, American Express, PayPal, Coinbase and Revolut. It centres on mandates, which are signed digital records of a user's instructions.

• An Intent Mandate records the request, such as a product to find, and for delegated tasks can include rules like a price limit.
• A Cart Mandate records the exact items and price once approved, either by the user or automatically if the earlier rules are met.

The chain from intent to cart to payment creates an audit trail. Google says AP2 can handle credit and debit cards, real-time bank transfers and stablecoins.

How do agentic payments work with crypto and stablecoins?

The crypto link runs through x402, an open standard that puts payment requests inside ordinary web requests. Google says it worked with Coinbase, the Ethereum Foundation, MetaMask and others on an A2A x402 extension for agent-based crypto payments. How x402 itself works is covered in what x402 is.

Stablecoins suit this because an agent can pay small amounts at any hour without a card form, settling on a blockchain. The background on these tokens is in what a stablecoin is. Visa also said it was working with Coinbase on compatibility between its protocol and x402.

Are agentic payments already in use?

They are at an early stage. In December 2025 Visa said partners had completed hundreds of agent-initiated transactions in controlled tests, with US pilots covering consumer and business purchases. It predicted that millions of consumers would use AI agents to buy things by the 2026 holiday season, and planned pilots in Asia Pacific and Europe for early 2026.

The risks are familiar. An agent with spending power is a target, much like a wallet with a broad token approval. The rules about how much it can spend and when matter as much as the technology. For how merchants take digital payments today, see how businesses accept crypto payments.
