Call any x402-protected API with automatic payment. Payment is the authentication — no API keys or subscriptions needed.

Your wallet is auto-created on first use and stored at ~/.agentcash/wallet.json.

Payment is automatic: sends request, gets 402 challenge, signs USDC payment, retries with credential, returns result. Payments settle only on success (2xx) — failed requests cost nothing.
