The x402 payment protocol was responsible for developing and launching the AI marketplace.
Coinbase unveiled Agentic.market, a new marketplace where AI agents can independently discover, compare, and connect compatible services without using API keys, paying with stablecoins.

The platform is built on the x402 payment protocol, which Coinbase launched in May 2025. Available services already include CoinGecko, Google Flights, and social network X.
How Agentic.market Works
The marketplace has two layers: a web interface for humans and a software layer for AI agents. The latter allows agents to search, filter, and integrate new services in real time without human intervention.
Each service provides AI agents with “skills”—ready-to-use code for interaction—as well as a wallet that enables the agent not only to buy but also to sell services. Payment occurs directly in stablecoins.

Industry Support
The x402 protocol has already received widespread support. In early April, Google, Microsoft, and Amazon Web Services announced the creation of the x402 Foundation to further develop the standard. Visa, Mastercard, Stripe, Circle, Base, Polygon Labs, Solana Foundation, and other major companies have also joined the initiative.
Coinbase CEO Brian Armstrong previously stated that “soon there will be more AI agents transacting online than humans.“
