Real-time Solana price in USD, aggregated from multiple exchanges — Ed25519 signed attestation

BNB Chain token risk score and honeypot check from a BEP-20 contract address, with every deduction explained

Wire-In Lookup — per-entity merchant-seat verdict. Pass ?ua=<counterparty-UA>; get ONE signed row: score (0.0-1.0 payment-reliability observed at this seat), confidence, verdict (settled | attempted_payment | probe_only | low_signal | unknown), observed counts, Ed25519 attestation. $0.01 USDC/entity on Base or Solana. Fold the score into your own counterparty model — wire it into your scoring loop. Wallet lookup (?wallet=) is v2.
