I guess the Web Url lesson number is meant by Corinnebelle in the browser, the last number at the end.
For the earlier/last gold Unit there is the "Level Up" button:
https://www.duolingo.com/lesson/unit/xx/level/11
It's several times 11 in my Portuguese course and it matches the count of all circles, stories and chests.
But I always see that purple Level-Up text there?!? Later units beyond 49 (of 75) are locked/grey.
Maybe Legendary Unit tests need to be specifically written or enabled by programmers or course maintainers??
..(...)..
For a normal circled lesson: I don't see it on Chrome Dev.
Starting Lesson 6 of 8 on Infinitive only shows as the Url:
https://www.duolingo.com/lesson
You probably can see all the Api calls in the Firefox Developer Tools Network tab.
What course and Unit is it? Hebrew? All newly added Units 43 to 54?
Does that Unit have 30 circles/stories/chest so the next logical number would be 31?
How about the others you can't access?
[mention]MatOzone[/mention] generates those thread Course Unit overviews which always include some fancy numbers in it:
viewtopic.php?t=8424-hebrew-from-englis ... a-54-units
The Goal is the total number of all items per Units (including chests and stories for other languages).

Just add these lesson numbers and Chests from the above Hebrew overview thread for later Units and you should be good.
I understand that the Goal count is always different for Hebrew Units.
