Confirmed offline
Nothing confirmed offline.
Flawless providers
No provider qualifies yet.

Price gaps compare the catalogue entry with the amount actually demanded. Offline means an endpoint failed two consecutive valid runs. Flawless means every endpoint of that provider answered correctly in every valid run, at the price it advertises.

Look up a provider

Scores are still building. Measurements from this location began on 2026-08-12. An endpoint needs five valid measurements before it receives a score, so the lookup and the score breakdown below open up in a few days. The market figures above are current as of today.

How the market is growing

Listed endpoints per measurement day. New arrivals outnumber departures, but the churn is substantial in both directions.

Checking our own measurement

An auditor has to audit itself first. Below is the share of pure network errors per run. When that figure leaves its normal range, the cause is on our side, so we discard the run rather than let it count against providers.

network errors 0.32% 12/8

Network error rate per run. Runs marked in red are excluded from scoring.

Price honesty

Every measurement compares the price listed in the Bazaar catalogue with the price the endpoint actually demands in its payment request. 28 endpoints ask for more than they advertise. The largest gaps:
