Coinbases X402 Launches Agentic.market To Expand AI Agent Payments

Coinbase-backed AI payments protocol x402 has launched Agentic.market, a new platform built to help AI agents find and use compatible online services. 

The launch adds a discovery layer to the protocol by offering a single place where users and AI agents can search for tools that support x402-based payments.

Coinbase product lead Nick Prince said the platform aims to “give humans and their agents access to thousands of services, with zero API keys required.” He described Agentic.market as a storefront where users can discover, compare, and use services that work with x402.

Prince said the platform addresses a gap in the AI agent market. He said many users have depended on scattered information and informal recommendations to find services that AI agents can access. Agentic.market is designed to solve that issue by organizing those services in one place.

The marketplace includes services and websites that AI agents can use, such as CoinGecko, Google Flights, and X. Prince also said the platform includes a web interface for people and a programming layer that lets AI agents search, filter, and connect to services on their own during operation.

Additionally, the x402 protocol launched in May 2025 and allows AI agents to make internet payments using stablecoins. It takes its name from the rarely used HTTP status code “402 Payment Required.” Coinbase and its partners present the protocol as infrastructure for AI-driven online commerce.

Prince said the platform gives an AI agent “skills,” or code that explains how to use a service. He added that agents also get a wallet, which allows them to “buy services and also sell services.” This setup is meant to let agents complete more tasks without requiring direct human control for each action.

Earlier this month, Google, Microsoft, and Amazon Web Services backed the launch of the x402 Foundation, which will govern the protocol. American Express, Mastercard, Visa, Cloudflare, Shopify, Stripe, Circle, Base, Polygon Labs, the Solana Foundation, Thirdweb, and KakaoPay also expressed support for the initiative.

“There will be more AI agents transacting online than humans very soon,” noted Coinbase CEO Brian Armstrong.

Circle CEO Jeremy Allaire made a similar forecast in January, saying “literally billions of AI agents” could transact on blockchains within three to five years. The launch of Agentic.market places x402 more directly within that growing AI payments push.
