Coinbase



$1.12B

developers Kevin Leffew and Lincoln Murr have introduced the x402 payments protocol, a tool designed to let artificial intelligence (AI) agents carry out transactions on Ethereum
ETH


$4,508.22

 without any human assistance.

The protocol allows software to automatically receive a payment request, send a stablecoin transfer, and receive the result. It has already been published on Coinbase’s GitHub page.

Their work highlights a web feature called HTTP 402, a status code originally created to signal that a payment is required before content is delivered. Although rarely used in practice, Leffew and Murr noted that this standard can serve a new function on Ethereum.

By combining HTTP 402 with Ethereum Improvement Proposal 3009 (EIP-3009), which allows token transfers through signed messages, the x402 protocol enables agents to act on behalf of users without needing full access to private keys.

This makes it possible for bots to complete transactions with only permission to act, rather than full control of wallets.

This system could support a wide range of use cases. An autonomous vehicle, for example, could pay for tolls or fuel on its own. AI-based software could purchase access to online services or data. Even tasks like long-term file storage could be handled directly by machine agents using stablecoins.

Leffew and Murr also pointed out that Ethereum’s ability to support secure transactions, along with the availability of stablecoins, allows AI agents to follow rules, settle payments, and reduce the need for human oversight.

On May 6, the cryptocurrency exchange Coinbase



$1.48B

announced a new payment tool called x402.

This system allows apps, websites, and artificial intelligence (AI) programs to make stablecoin payments directly over the internet using the standard web protocol, HTTP.

Coinbase designed x402 to revive a rarely used part of HTTP called the “402 Payment Required” code. By updating this feature, x402 makes it possible to send and receive payments as easily as sharing data online.

The goal is to help both people and AI agents pay for services in a quicker and more efficient way. Erik Reppel, co-author of the x402 white paper and head of engineering at Coinbase Developer Platform, explained:

We’re laying the groundwork for an economy run not just by people, but by software — autonomous, intelligent, and always on.

One of the key benefits of x402 is to give AI agents more freedom, so they can pay for what they need, such as data access, computing power, or other services, without waiting for humans to top up credits or manage accounts.

For developers, x402 offers a way to charge users based on how much of a service they use. This could replace flat-rate subscriptions or credit card minimum payments. Content creators may also benefit by receiving stablecoin payments without relying on broad subscription models.
