VERDICT
ranking generation 3Not ranked yet: this listing was not in the ranked pool for AI the last time we built it, which happens at most once a minute. A service listed moments ago enters at the next rebuild.
ALTERNATIVES IN AI
Other AI services in this directory, ordered by the same measured score. The figures are ours: 30-day uptime from our own probes, 30-day settlement volume read on-chain (a conservative undercount, and null where we cannot measure it, never a zero).

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

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.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share is a concentration signal, not part of the ranking score.

] OVER TIME
All charts use the 7d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/altahub-vivarium-autonomous-machine-services/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). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
Median across 2 endpoints. Use the selector to isolate one.

Measured site and economics pillars from the assessment history, so the latest value shown elsewhere on this page reads as a point on a trend rather than a permanent state.
