grade evidence: hourly probes of /v1/add-business-days. 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.
Adds or subtracts working days from a date in 100+ countries (any ISO country code), skipping the local weekend and public holidays, and lists the holidays skipped. Verified calendars for South Africa and 10 African countries (Egypt has a Friday-Saturday …
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.
