A solo developer built AOTrust, a service that cryptographically notarizes AI agent outputs for $0.01 per proof on Base L2. It issues a 239-byte Provenance Data Record (PDR) using the HTTP 402 payment…
A developer built an MCP server that charges AI agents per call using x402 micropayments, a protocol based on EIP-3009 that enables machine-to-machine payments without human sign-up. The server uses a…
Cinderwright has launched a proxy service that lets AI agents call over 2,800 paid APIs — including weather, translation, and Bitcoin price lookups — without implementing any crypto payment logic. Dev…
MCPize launched x402 payments in production, enabling AI agents with EIP-3009 wallets to pay for MCP tool calls in USDC on Base mainnet. The first payment of $0.01 settled in four seconds, bypassing s…
