Daily history →. Observed transfers show value arriving at the payout address; they do not establish service revenue.
Receiving wallets are payment addresses published for this service. Sending wallets transferred funds to an exclusive receiving address; this alone does not prove a purchase or identify an agent.

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.

Chosen by category and by whether we have measured them, not by who pays us. A sponsored placement in this list is labelled as such.

“exact” is the price per call. “upto” is a ceiling the client sets, not a price. Atomic amount 10000 = 0.01 USDC per call on Base.

Examples are the provider's own, not a call we made.
The observed inflow implies about 7 calls at list price; the source counted 7 (factor 1). A transfer is still not a purchase, but the order of magnitude holds — this is the strongest monetisation signal in the catalogue short of a receipt feed.

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 $0.07 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 7 calls; the source counted 7. 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.

A payment rail is where the provider asks to be paid. It is not proof that anything was paid through it.
One row per statement. “Verified” means we checked it ourselves and the finding is quoted. “Provider claim” means we read it in the provider's own record. “Not found” is a statement about our search, not proof of absence.
