The check gives a false positive:

$ python dumpgenerator.py --xml --api=https://world-of-shinobi.fandom.com/ru/api.php
Checking API... https://world-of-shinobi.fandom.com/ru/api.php
MediaWiki API URL not found or giving error: HTTP 410
API not available. Trying with index.php only.
Checking index.php... https://world-of-shinobi.fandom.com/ru/index.php
index.php is OK

Then of course it fails with
