What the report holds

Per payTo wallet the registry lists for your host, over the Atlas’s window of daily pulls. Wallets are shown in full: it is your own customer list, read from a public chain. Nothing in it says who holds a wallet, and nothing in it is a score.

A real report, blurred

x402 payments on Base · 26 October 2026 – 4 November 2026 · 8 days · registry as of 5 November 2026

The busiest seller in the window, by buyers, among those whose buyers also paid at least five other sellers (so every section has something in it): api.onesource.io. This is one of its payTo wallets as the report shows it, with every number blurred to a range, every buyer wallet masked and each long list cut to three rows. Your report has the exact figures and every wallet in full.

After checkout Polar sends you a license key; an Atlas Pro key works too. Type your host and the key, and the report opens below. The key goes from this browser to https://ausrine-who.onrender.com in the X-Atlas-Key header and nowhere else.

A host that is not in the registry, not in the window, or was not paid in it is refused before any payment and never charged. The docs.

What the numbers are, and are not

• A wallet is not an agent, and nothing here says who holds or runs one: a wallet is listed because it paid this seller's payTo wallet on a public chain.
• X402 payments only: transfers a facilitator settled on a buyer's signature, on Base; money that reached the same wallet by ordinary transfer is not a call and is not counted.
• The window is the Atlas's daily pulls, up to 8 days: a buyer from before the window is not seen, so new means new to the window.
• Each payTo wallet is read on its own, across every host paid into it: a wallet shared by several hosts carries all of their buyers.
• No score and no single number for a seller: every figure is a count with its dates, and the rivals are the sellers that share its buyers, not a judgement of anyone.

buyer

a wallet that paid this payTo wallet over x402 in the window

came back

a buyer that paid on 2 or more distinct days of the window

loyal

the buyers that came back: most days paid, then most payments

new buyer

first seen in the window on that day; on the window's first day every buyer is new to it, since the window holds nothing before

lost

a buyer that paid only on days in the first half of the window, and not after

left for

a lost buyer that started paying the other seller only in the second half

arrived

a buyer that paid only on days in the second half of the window

came from

an arriving buyer that had paid the other seller only in the first half

bought alongside

buyers this wallet shares with another seller in the window

early buyers

the wallets that paid it on the window's first two days, when its buyers on the last day are at least 10 and at least 3 times the first day's

rivals

the 5 sellers sharing the most buyers with this wallet, side by side with it: a comparison, not a verdict

halves

the window split in two; with an odd number of days the middle day is in neither half

busy

buyer wallets that paid more than 30 sellers in the window are left out of bought alongside, left for and came from, and each list says how many: a wallet that pays everyone says nothing about what goes together or who moved
