Availability is the one component that is a success rate, so it alone carries an evidence discount: it enters as the 95% Wilson lower bound of the measured share (cubed), which is why its bar reads below the raw percentage above — thin evidence scores below a long proven record. Latency, price, protocol and consistency are direct measurements, shown as-is.

grade evidence: hourly probes of /fx. Availability, latency and protocol measure the operator's shared infrastructure and generalize across its products; the price check applies to the probed product. We now also probe one other product per hour, rotating; "live price we measured" shows what each answered.

What this grade does and doesn't measure: it scores the paid-request handshake — whether the service returns a spec-valid 402 payment challenge, how fast, and whether its price is honest. We do not pay these endpoints yet, so we do not verify that the paid response returns correct or complete content. Availability is a probe success rate measured hourly, from a single network vantage for this service.
