Coinbase has introduced Agent.market, a revolutionary marketplace powered by its x402 payments protocol that enables AI agents to discover and purchase online services without traditional API keys or subscription models.
Erik Reppel, who leads engineering at Coinbase Developer Platform and created the x402 protocol, characterizes the platform as an “app store for agents.” The marketplace categorizes available offerings into seven distinct sections: Inference, Data, Media, Search, Social, Infrastructure, and Trading.
Initial service providers span multiple categories, featuring OpenAI and Venice in the inference space, Bloomberg and CoinGecko for data services, LinkedIn and X for social networking, plus AWS Lambda and Alchemy for infrastructure needs. The marketplace operates on a permissionless basis, allowing providers to join freely.
Coinbase first introduced the x402 protocol in May 2025. The protocol’s name derives from the seldom-utilized HTTP status code “402 Payment Required.” Its core functionality enables AI agents to execute immediate payments through stablecoins and conventional payment systems.
The x402 Foundation oversees the protocol as an open standard under the Linux Foundation umbrella, with financial and strategic support from more than 20 corporations. This roster includes Google, Microsoft, AWS, Cloudflare, Stripe, Visa, Mastercard, American Express, Shopify, Circle, Base, Polygon Labs, and the Solana Foundation.
A Growing Market for AI Agents
Approximately 69,000 AI agents are currently active on the x402 network. These autonomous systems have collectively executed more than 165 million transactions, generating a total transaction volume exceeding $50 million.
According to Coinbase product lead Nick Prince, hundreds of thousands of AI agents have been conducting transactions but have depended on “fragmented sources and word-of-mouth” to locate compatible services. Agent.market was developed to address this challenge.
The platform features both a web-based interface for human oversight and a programmatic layer enabling AI agents to independently discover and integrate services without human intervention.
How Pricing Works for AI Agents
Most services listed on Agent.market implement usage-based pricing models, with certain providers adding an “agentic premium” for automated bot access. According to Reppel, businesses can also provide subscription options to decrease per-transaction costs for AI agents with high transaction volumes.
Reppel emphasized that the protocol reduces barriers for emerging businesses seeking users, as agents can utilize services with minimal configuration and no API key requirements.
Coinbase CEO Brian Armstrong has predicted “there will be more AI agents transacting online than humans very soon.” Circle CEO Jeremy Allaire echoed this sentiment in January, forecasting that billions of AI agents will conduct transactions on blockchain networks within three to five years.
At its initial launch, Agent.market operates with an open enrollment system, permitting any provider to join without undergoing an approval procedure.
