This is my link for getting one random article using Wiki API:

```
https://en.wikipedia.org/w/api.php?%20format=json&action=query&prop=extracts&exsentences=2&exintro=&explaintext=&generator=random&grnnamespace=0

```

I need to get from it the first two sentences of the first section, and it works pretty well. 

---

I want to use this kind of link and search this random article in a specific category. This is what I have tried after searching online:

```
https://en.wikipedia.org/w/api.php?%20format=json&action=query&prop=extracts&exsentences=2&exintro=&explaintext=&generator=random&grnnamespace=0&cmtitle=Category:Music

```

(I have added this part to the original link: `cmtitle=Category:Music` )

It doesn't work for me.
It gets the random article like the first link (not under a wanted category, which is Music in this link).

There is no API to get a random category member (and using a parameter from some unrelated API module is certainly not going to help). You could screen scrape [Special:RandomInCategory](https://en.wikipedia.org/wiki/Special:RandomInCategory) (or turn it into an API module - [patches welcome](https://phabricator.wikimedia.org/T63840) :)
try to use `cmlimit` to get all of the catgeorymembers, then use a programming language, like [Python](https://python.org) to request the page, then store every catgeory in an array, and use the `random` module to get a random catgeorymember from the array you stored them in. then you can use it in a link to get the specific page for the categorymember or anything else that you need.
