VERDICT

ranking generation 3

Not 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).

ASSESSMENT

updated 2h ago

The parts the verdict above is computed from, each with its proof. Click any chip. Measured values stay read-only; unknown is honest, and an unknown is never counted as a zero.

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

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 part of the ranking score: a higher share lowers the traction part of the score, by up to half when one address holds all 30d volume.

OVER TIME

All charts use the 90d 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.
