VERDICT

ranking generation 3

Not ranked: Infrastructure holds 2 measured services in total, under the 4 we require before publishing a position. The scoring is pool-relative (price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included), so on a field this small the number would be measuring how empty the category is, not how good the service is. Everything we did measure on it stays published below.

ALTERNATIVES IN INFRASTRUCTURE

No ranked comparison in Infrastructure yet: fewer than 4 services here carry enough measurement, and a table of bands drawn from a field that small would flatter whoever stands in it. The measured figures of each listing stay on its own page.

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 a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/decision-anchor/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.
