These are observations, not accusations. A band of LOW, MEDIUM or HIGH describes how much of what we check we were able to confirm — it is not a judgement about the operator of an endpoint. Every signal, its weight and its rationale are published on the methodology page, and any operator can claim an endpoint, correct a fact or opt out.

What this table does and does not say
- 1 of 15 endpoints here has no observed terms yet. Each says which state it is in — not in our index, not probed yet, no x402 challenge served, or did not answer — and none of them is shown as a zero.
- Availability and latency are not shown here. They are aggregates over the sampled probe dataset and are read one endpoint at a time, which is what the history page does — this page reads the index and makes no outbound request. Estimating them from the probe records kept in the database instead would over-report failure, because routine successful probes are deliberately not kept.
- Usage figures on this page are published by the facilitator that lists the endpoint (coinbase-cdp), not measured by us. They are shown because they are better data than anything we can collect — and attributed because they are somebody else's.
- The facilitator's listing and the challenge we observed disagree about the price of api.babyblueviper.com: the listing advertises 26017 and the endpoint served 25227 atomic units. Both are recorded; the amount we observed is what the endpoint actually asked us for.
