2 findings from measured data

Payment attribution is blocked

The payout address is shared with 369 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.

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 $0.01 — 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 369 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. See evidence levels.

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.
