What you get

Probe any x402 endpoint from the buyer side before paying: we send the unpaid request, decode the 402 challenge and return its payTo address, price (amount), scheme, network and x402 version, plus a verdict: sellable / no_gate / plain_402 / error. Never pays. Ideal pre-flight for agent purchase decisions.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
