The x402 Foundation, backed by Coinbase, has officially launched Agent.market, a unified marketplace described as an "app store for agents." The platform aggregates AI-powered services and tools that operate through the x402 blockchain-based micropayments protocol, positioning itself as a central access point for the emerging field of agentic commerce.
The x402 protocol, created by Coinbase Developer Platform engineering head Erik Reppel, leverages the unused HTTP 402 'Payment Required' status code to enable instant micropayments. This allows websites and APIs to request payments through both blockchain and traditional financial rails, enabling AI agents to transact without the need for lengthy onboarding processes or managing API keys.
The protocol is governed as an open standard under the Linux Foundation and boasts support from over 20 major technology and crypto firms. Key backers include Cloudflare, Stripe, AWS, Google, Visa, Base, Circle, and the Solana Foundation.
Agent.market categorizes services into seven distinct sectors: Inference, Data, Media, Search, Social, Infrastructure, and Trading. The platform has launched with dozens of providers already listed. Notable participants include OpenAI and Venice in Inference; Bloomberg and CoinGecko in Data; LinkedIn, X, and AgentMail in Social; AWS Lambda, QuickNode, and Alechemy in Infrastructure; and Bankr and Coinbase RAT in Trading.
Pricing is set directly by providers, with most services charging per request, though some apply an "agentic premium." Erik Reppel explained that high-frequency users may opt for subscriptions to reduce costs, stating, "If you’re using it a ton, you’re more likely to go subscribe and then it brings your costs down." He emphasized that this model reveals latent demand for products that were previously unviable due to API key limits and microtransaction fees.
The foundation reports a thriving ecosystem, with approximately 69,000 live agentic bots on the x402 protocol. These bots have executed over 165 million transactions, generating a total transaction volume of $50 million. The marketplace operates on a permissionless basis, allowing any provider to join without seeking approval, which the foundation believes will further accelerate adoption and innovation in automated, machine-to-machine payments.
