Agentcash

This server handles the x402 payment protocol automatically when calling APIs that require micropayments for access. Instead of manually managing payment headers and transaction flows, you point it at an x402-protected endpoint and it negotiates the payment handshake behind the scenes. Reach for this when you're working with APIs that use pay-per-call or metered access models through x402, and you want Claude to interact with them without implementing the payment logic yourself. The source doesn't specify particular API integrations, so you'll need to configure it for whatever x402-enabled services you're targeting.
