Coverage includes retained scans only, not every historical transaction. Earlier daily totals cannot recover sender addresses. Sender lists exclude shared receiving wallets, whose transfers could belong to another service. A provider address does not establish wallet ownership.
Sorted by source-measured calls, not by our opinion. The right-hand figure is observed inflow, which stays empty for peers whose address is shared.

Examples are the provider's own, not a call we made.
The observed inflow implies about 312 calls at list price; the source counted 37 (factor 8). Either the effective price differs from the list price, or part of the volume belongs to other payers on the same address. Do not read the inflow as this service's revenue.
Peers with attributed inflows →289 of 30,771 services (0.9%) in Crypto & Payments have attributable inflows; 26,269 have a source-measured call count. Median measured calls: 2.

Observed transfers
· confidence medium
Token transfers reached this service's own payout address. A transfer is not a purchase, and shared, refunded or unrelated transfers cannot be excluded.
Why revenue is “unknown”. A revenue figure needs a receipt: an amount a buyer actually paid for this service. We hold none for this entry, and we hold no funds at all. What we have instead is $0.312 arriving at the payout address in 30 days — that is volume, and a lower bound: transfers can be refunds, treasury moves, or payments for something else entirely.
Cross-check. At the published price the observed inflow would cover about 312 calls; the source counted 37. Two independent measurements of the same question — they never match exactly, because the effective price differs per call size and the address can also receive unrelated transfers.
