Listed Vs. Actual Price
Listed = the price in the directory listing today, for the main route we test. Actual = the price that route asked for when we called it (from our signed records). Some differences are normal, like prices that depend on the request.

Retry Safety
This seller's payment request advertises x402's payment-identifier extension and marks it required: a retry key that lets a service recognise a resent request. This is what the seller states. We have not run our Resent Payment Check on this service (how it works). Seen 13 min ago.
