x402-stacks is a TypeScript library that enables automatic HTTP-level payments for APIs and digital services using the x402 payment protocol on the Stacks blockchain. It allows developers to implement pay-per-use pricing models where clients automatically pay for API access using STX or sBTC tokens, with features like HTTP 402 payment handling, Express.js middleware, and support for both mainnet and testnet networks.
