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.

No sending wallet addresses have been retained for this service. Buyer wallets are unknown; daily totals and reported payer counts do not reveal their addresses.
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.
| Network | Scheme | Amount | Asset |
|---|---|---|---|
| Base | exact | 0.25 | USDC |
“exact” is the price per call. “upto” is a ceiling the client sets, not a price. Atomic amount 250000 = 0.25 USDC per call on Base.

Examples are the provider's own, not a call we made.
The payout address is shared with 21 other service(s). That is normal for facilitator and platform addresses, and it is why this profile shows no inflow figure. The volume exists — it just cannot be split without inventing a rule.
How attribution works →287 of 30,055 services (1.0%) in Crypto & Payments have attributable inflows; 25,633 have a source-measured call count. Median measured calls: 2.

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 an activity value of $1.00 — the source's call count multiplied by the published price. That is what the list price implies, not what anyone paid. The payout address is also published by 21 other service(s); the volume cannot be attributed to one of them.

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.
