1 of 9 comparable · rubric v7
Only the most recent audit was measured with rubric v7; the other 8 used earlier rubrics and are on a different scale. One audit is not a range, so a single score is shown instead of best, average and worst.
This score is higher than 94 % of the 11063 sites measured on rubric v7.
The comparison set is the URLs people submitted to AgentFit, not a curated list of API documentation: it places this host among what was submitted, not in the market. Much of what was submitted is not API documentation at all and scores near zero — about a fifth of the set sits below 10 points — so a percentile here flatters a score compared with how it would rank among documentation sites. Counted on 2026-09-11. Each rubric version is ranked separately, because the versions are different rulers.

Each rubric version is a different ruler: the rows are the same site measured different ways, and they do not form a trend.
