Payment
- With a wallet — set
X402_PRIVATE_KEY(a wallet funded with USDC on Base). Every call is paid automatically (gasless x402). This is the normal mode for autonomous agents. - Without a wallet — tools return the HTTP 402 payment instructions so your host can pay however it wants.

Example — a pre-trade safety gate
An agent building a trade calls honeypot_check(address, chain) and only proceeds when verdict is OK or CAUTION — turning "can I buy this?" into one paid call instead of a per-chain simulation stack.
