Description (from the catalogue, unverified)
SpendPreflight — trust and verification tools for stablecoin payments, built for AI agents and the people who run them. Payment Preflight: check an x402 challenge or cart against caller spending/sanctions rules and cached evidence. Returns allow/hold/block, reasons and a receipt. Missing/stale evidence stays unknown. No merchant fetch, signing, settlement or custody. Payee binding is a separate check. Allow is not identity verification, safety, compliance certification or proof of paid delivery.
