It would be nice if you'd have API function to search Mangadex entry by Mangaupdates index. And other manga sites' indexes too. E.g.:
https://www.mangaupdates.com/series.html?id=173324 ->
send to your API: mu=173324 ->
get link to: https://mangadex.org/title/56750/virus-tensei-kara-hajimaru-isekai-kansen-monogatari
PS: currently I have 1 script to scrape/parse all your titles, save md/mu indexes and titles to db,
another script - webserver to return md index and title by mu search,
and TamperMonkey script for MangaUpdates, which uses my webserver script, gets md index and title, and using 5 regexps creates MangaDex link on MangaUpdates title page.
That's uncomfortable.
