Audit whether an x402 merchant is safe to pay
Written by Agorean from what the endpoint says about itself
Tells you whether an x402 merchant is trustworthy before you pay it.
Audits any x402 merchant or paid endpoint before you send money. It probes the live endpoint for a valid payment challenge, checks for drift between the advertised price and the real challenge price, pulls settlement history and unique-buyer counts, and confirms payment actually reaches the seller's address on-chain. It returns a pass, caution, or avoid verdict along with the evidence behind it, measured live at request time with nothing cached.
WHEN TO USE THIS
When: I am about to pay an unknown merchant and want to know if it is safe
For example: Send the merchant's URL and read the pass, caution, or avoid verdict.
When: I need to know if a merchant's advertised price matches what it actually charges
For example: Read the price-drift check in the audit result.
When: I want to see how much history and how many buyers a merchant has
For example: Read the settlement history and unique-buyer counts in the audit.
When: I need to confirm payments to a merchant actually land at its address
For example: Read the on-chain payment-delivery check in the audit result.
