kristo-intelligence-api.onrender.com/api/v1/seller-check

Check whether an x402 seller is really being paid before you pay them: a read of any Base address you name, with distinct paying addresses, repeat-payer concentration, treasury-sized flows separated from per-call payments, and the read's own coverage stated. Useful immediately before paying an unfamiliar x402 seller, when on-chain evidence is wanted first.
