risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Attributed pro-quota: this payout address is shared, so volume and buyers are the operator-level figure divided by the services sharing it. A declared convention, not an individually observed measure, and still a conservative undercount.
Top buyer share is a concentration signal, not part of the ranking score.

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/uk-hmo-licence-api/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
Median across 3 endpoints. Use the selector to isolate one.
Shared payout address (5 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 6 services sharing it: a declared convention, not an individually observed measure.
