Coinbase-backed x402 launches Agent.market

Coinbase-backed x402 has launched Agent.market, a unified marketplace where AI agents and humans can discover and pay for services using the x402 protocol and instant micropayments. Erik Reppel, head of engineering at Coinbase Developer Platform and creator of x402, described the marketplace as an “app store for agents.”

The x402 Foundation, which manages the protocol as an open standard under the Linux Foundation, released the marketplace. The protocol is named after the HTTP 402 “Payment Required” status code and lets websites, APIs and autonomous agents request and receive immediate micropayments over both blockchain and traditional payment rails.

At launch, Agent.market lists providers across seven categories: Inference, Data, Media, Search, Social, Infrastructure and Trading. Available services include OpenAI and Venice for inference; Bloomberg and CoinGecko for data; LinkedIn, X and AgentMail for social; AWS Lambda, QuickNode and Alchemy for infrastructure; and Bankr and Coinbase RAT for trading. Providers can join the marketplace permissionlessly.

Reppel reported about 69,000 live agentic bots on x402 that have completed more than 165 million transactions, totaling roughly $50 million in volume.

Most services on Agent.market charge per use. Some apply an “agentic premium” to requests made by bots. Reppel added, “But if you're using it a ton, you're more likely to go subscribe and then it brings your costs down.”

He also said agents can access services with minimal setup and may not require traditional API keys or upfront subscriptions, which can lower activation costs for startups and other businesses aiming to reach users through agents.

The x402 Foundation lists support from more than 20 tech and payments firms, including Cloudflare, Stripe, AWS, Google and Visa, and from crypto infrastructure groups such as Base, Circle and the Solana Foundation. Governance under the Linux Foundation is intended to keep the protocol open and interoperable across web services and payment rails.

The protocol standardizes message flows and payment methods to enable instant micropayments and reduce friction for low-value transactions. Agent.market combines discovery, pricing and payment flows so agents and human developers can include services in automated workflows.
