Data Lookup API

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.

The payment requirements as published to the catalog. Read the live 402 before paying: a price here is a claim, not a quote.
