Just a few minutes ago I introduced an API into ari-web, it's a static API, though it's nice for fetching information about the webite in JSON if you don't want to parse sitemap.xml :)
Anyway, the home page for the API is: https://www.ari.lt/api it will show you the list of all APIs available
An example of an available API: https://www.ari.lt/api/sitelist.json it will give you the list of sites on ari-web :)
Anyway, enjoy if you ever need to interface with ari-web :) Also if you need any more APIs you can make an issue on https://www.ari.lt/git or discuss it on https://user.ari.lt/ :)
Good bye!
