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.

Live 402 challenge

Captured by the enrichment pass, not read just now. Prices can change. Always read the 402 the endpoint answers with.

'Not confirmed' does not imply the company is invalid. Machine-readable errors with per-member-state availability status."
