Check whether a counterparty is SAFE TO PAY before sending money. Given a URL or host, returns a 0-100 trust score and risk band (low/medium/high/critical), detecting scams, phishing, and known-malicious endpoints via threat feeds, domain risk heuristics, and a community reputation graph. Call this before paying any merchant, API, agent, or x402 resource. Free — for the full explainable reasons AND a signed, verifiable attestation (proof of the check for audit/disputes), call the paid POST /v1/check endpoint via x402.
