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.

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, corroborated by a second network path for this service.
