Description
pay.sh is an API gateway that enables AI agents and CLI tools to access paid APIs using stablecoins on Solana without accounts, API keys, or subscriptions. A CLI wrapper detects HTTP 402 payment challenges via x402 and Machine Payments Protocol (MPP), authorizes payments through a connected wallet, and retries requests with payment proof. A searchable catalog indexes API providers across categories including AI/ML, compute, data, and communications, enabling agents to discover and call services on a per-request basis.
