https://horizonpulse.dev/api/x402-check/sellerOverview
Pre-pay check of one x402 seller: unpaid 402 probes of the routes in its /.well-known/x402 (terms, schema and example lint), whether the Coinbase CDP Bazaar listing matches, a recent on-chain window for each Base payTo (distinct payers, repeat payers, first seen) with observed patterns, and an OFAC SDN snapshot screen. Facts with evidence, not a rating. Never pays or signs. Not charged if no x402 route is found. USDC on Base only.
