Recent payments · which agents last used it

Every indexed settlement paid to this service’s wallet, newest first. The index does not record which endpoint a payment was for, so if this wallet serves more than one endpoint, the rows include payments for the others. Paged up to the newest 5,000; the full history is on the merchant page.
