Pay Guard: allow/warn/block check before an x402 payment. Send your plan (domain, max_price_usd) plus the 402 challenge (payTo, amount, asset, network, resource). Checks wallet↔domain match, price/asset/network, lookalike/URL safety, Agentropolis wash flags, an OFAC SDN screen of payTo and an optional LMX Labs signal. Deterministic, no LLM. Free allowance: 5 calls/day per client network with no payment: add header "X-Free-Allowance: use" (or ?free=1) to a valid request.
