Probegrade asks whether API data is right—not just reachable
Probegrade publishes API ratings based on checks for response-schema validity, data freshness, and comparisons with reference sources.
- For
- Agent builders and API data providers
- Worth noticing
- Its October 2026 preliminary rankings cite 201 probes; the page says paying for Verified does not change a provider’s score.
Field notes
Probegrade says scheduled automated probes check documented response schemas, compare embedded timestamps with request time, and record uptime and latency. Its October 2026 preliminary sample lists five sources from 201 probes; a separate beta section shows reference comparisons for exchange rates, crypto prices, weather, and IP-location data. The page says cross-checks are published beside scores but are not yet included in them, and that monthly editions are frozen with a probe-archive hash.
