Coinbase has introduced Agentic.market, a marketplace based on its x402 payments protocol. This platform allows AI agents to explore, evaluate, and conduct transactions with compatible web services using stablecoins, all without needing API keys.
Agentic.market offers both a user-friendly interface for human interaction and a programmable layer that enables AI agents to search, filter, and activate new functionalities on the fly. Each agent is provided with its own wallet, facilitating direct buying and selling of services within the platform.
The marketplace also features access to diverse services such as Google Flights and the social media platform X, among other options. According to Nick Prince, Coinbase’s product lead for x402, Agentic.market serves as a platform for discovering, comparing, and utilizing x402-compatible services, filling a gap where AI agents previously had to rely on fragmented sources to find suitable tools.
x402 protocol and institutional backing
The x402 protocol, named after the HTTP 402 Payment Required status code, was unveiled by Coinbase in May 2025. It enables AI agents to make payments across the internet using stablecoins. In April 2026, major technology firms such as Google, Microsoft, and Amazon Web Services joined hands to form the x402 Foundation, which will oversee the protocol’s governance. Initial support for this initiative came from a range of entities including American Express, Mastercard, Visa, Cloudflare, Shopify, Stripe, Circle, Base, Polygon Labs, the Solana Foundation, Thirdweb, and KakaoPay.
With multiple prominent payment networks and technology companies now backing x402, Agentic.market marks a significant step in integrating it as a foundational payments layer for AI-driven commerce. Coinbase CEO Brian Armstrong highlighted that soon, online transactions by AI agents will likely outweigh those conducted by humans. Jeremy Allaire, CEO of Circle, predicted in January 2026 that within three to five years, billions of AI agents would be engaging in blockchain-based transactions.
