Capabilities

Server instructions

Domduck tracks domain reputation over time and keeps the history permanently. This public server reads only what Domduck has already collected. It never fetches a domain on demand, so hasReading false means nobody has looked that domain up yet, not that the domain does not exist. One domain per call, 10 requests a minute per IP, and no history. Tranco rank and the blocked-crawler count are better when LOWER. Domain Rating and OpenPageRank are better when higher. A free Domduck account at https://domduck.com adds the dated history, unlimited tracked domains, a daily re-read of every source, and 240 requests a minute.

Known tools 3
