Trust · metricsHow CrawlCheck is used, and how often it is right.
One view of the network, the developers calling it, the trust numbers and the north-star metric, for the last 7 days. Every number links to the endpoint it came from; CrawlCheck’s own tests are counted apart and never in these figures.

Counts only: no caller address, key or site is stored with these numbers. Outside means not CrawlCheck's own tooling; it still includes people testing by hand. Weekly editions: /api/v1/metrics?week=YYYY-Www. Signed JSON: /api/v1/metrics (?days=1-30).
