x402-market

This server bridges Claude to any HTTP API that accepts x402 payments on Base mainnet, letting your agent pay for individual API calls on demand without subscriptions or API key management. It exposes a single tool, pay_and_call, that handles the payment and request in one shot. Reach for this when you want Claude to access premium APIs like real-time data feeds, computational services, or third-party tools that charge per use through the x402 protocol. The catalog endpoint suggests it maintains a directory of available paid APIs, though you'll need to fund the agent's wallet with Base tokens to actually make calls.
