tolca.tonbot.ca/v1/payment-check

Check an x402 endpoint before paying it: is this x402 seller safe to pay? Send the seller's URL (or its 402). One call screens the payTo wallet against OFAC SDN crypto addresses, checks official USDC on its network (13 networks incl. Base, Solana, Polygon, Arbitrum) and compares price and payTo with the seller's Coinbase Bazaar listing. Returns allow / review / block, invoice hash and Ed25519-signed receipt. Input: url or payment_required, optional network, seller_name.
