Where the caps are, and where they are not
one column costs moneyOne column here costs money to read and the rest do not, so one column has a cap and the rest do not. Domain Rating comes from Ahrefs and is capped at 100 domains a run without an account, 1,000 with one, and not at all for domains you already track.
Popularity rank, certificate expiry, DNS and AI crawler policy have no cap at any tier. We read those ourselves, straight from the domain or from a list already on our disk, so there is nobody to be unfair to.
Registration age caps at 25 a run, because the registries answer about ten requests a minute and we would rather tell you that than make you wait.
