grade evidence: hourly probes of /weather. 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. This operator lists 51 products; the grade is evidence from a small sample of them.
Weather for any coordinate. Current (default): temperature (C), relative humidity (%), wind speed, weather code — real-time. Historical: add start_date & end_date (YYYY-MM-DD, up to 92 days per call, archive lags ~5 days) for hourly history — backtest …
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.
