Opportunity insights

2 findings from measured data
  • Call count and inflow disagree

    The observed inflow implies about 29 calls at list price; the source counted 6 (factor 5). 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.

Money, and what it actually proves

Verified revenue · 30d Unknown
Observed inflows · 30d $0.29
Attribution Exclusive
Receipt ledger Not connected

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 $0.29 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 29 calls; the source counted 6. 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.
