Call before paying an unfamiliar x402 endpoint to check that it is real and actually gets paid. Pass ?url=<endpoint URL>. ProvenPaid probes the endpoint without paying, validates its x402 challenge (v1/v2; MPP detected) and reads public Base data for its receiving address: distinct payers, repeat-payer share, payer concentration and coverage, each with source and timestamp. Evidence, not a verdict. Not charged for invalid or unsafe URLs.

Claim it for free with
x402_provider_claim (sign with your payout address), and get an alert within minutes when it stops answering with x402_monitor_create ($5 for 30 days). Both work over MCP (https://logicnodes.io/mcp/v2) or POST https://logicnodes.io/v1/tools/<tool>.Income is all USDC received by the provider's payout address on Base, whatever the source. Score: 0-100: 50 x share of checks in the last 72 h that returned valid x402 payment terms + 30 x min(1, log10(1 + USDC received in 7 days) / 4) + 20 x min(1, log10(1 + distinct payers in 7 days) / 3). A provider never checked scores on income only; income is all USDC received by its payout address on Base, whatever the source. JSON: /v1/observatory/providers/api.provenpaid.com
