Relationships

4 buyers paid this seller over x402 on 3 of the window’s 8 days: 4 payments, $0.03. 0 of 4 buyers came back on another day (0%).

In the full record: its most loyal buyers, what is bought alongside it, who left it for whom, who came to it from where, and its early buyers, each with the counts behind it. How to get it: the $0.001 check over x402, Atlas Pro at $49 a month and for the seller itself, the Your buyers report at $29 a month.

Relationships are patterns in the x402 payments we observe on Base over the window: a buyer is a wallet that paid this seller’s payTo wallet, and came back means it paid on two or more different days. A wallet is not an agent, and a relationship is a pattern of payments, not a claim about who anyone is or who runs a wallet.

Is this your service? See who your buyers are: every wallet that paid you, day by day, and where the ones that left went, in one report.
