Blockchain wallets

Full addresses · public payment evidence

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.

Sending wallets · observed counterparties

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.

Opportunity insights

2 findings from measured data

  • Payment attribution is blocked

    The payout address is shared with 97 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 →

  • Category benchmark

    42 of 2,768 services (1.5%) in AI Models & Inference have attributable inflows; 912 have a source-measured call count. Median measured calls: 2.

What the provider says

Give it conditions, drugs or sponsors. For each it queries ClinicalTrials.gov and composes ONE landscape brief: counts by phase and status, recruiting-now, top sponsors, interventions and countries, median enrollment and recent starts. Keyless and agent-callable. Up to 3 items per call; failed lookups are not charged.

The payout address is also published by 97 other service(s); the volume cannot be attributed to one of them.

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 $0.12 — 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 97 other service(s); the volume cannot be attributed to one of them.
