Api Endpoint

api.provenpaid.com

Call before paying an unfamiliar x402 endpoint to see whether anyone actually pays it. Pass ?url=<endpoint URL>. ProvenPaid reads public Base data for the endpoint's receiving address: distinct payers, x402-style payments, repeat-payer share, payer concentration and coverage over 30 days. It also validates the x402 challenge (v1/v2; MPP detected) without paying. Each item has source and timestamp. Evidence, not a verdict. Not charged for invalid or unsafe URLs.
