We would like to have one or more endpoints for feeds, to be used initially by the mobile apps. See T132340 for details.
Since this information is not page specific and lists multiple pages in the response it doesn't make much sense to put it under `/page/...`.
The current thinking is to use `/project/...` instead:
```
https://{domain}/api/rest_v1/project/
+- today/feed <- aggregating endpoint
+- today/article
+- today/picture
+- today/news
+- random
+- ...
```
Examples:
* https://en.wikipedia.org/api/rest_v1/project/today/feed (An aggregating endpoint comprised of the ones below, which are the non-user specific portions of the Explore feeds in the apps).
* https://en.wikipedia.org/api/rest_v1/project/today/article (The "Article of the day")
* https://en.wikipedia.org/api/rest_v1/project/today/picture (The "Picture of the day")
* https://en.wikipedia.org/api/rest_v1/project/today/news ("In the news" entries)
* https://en.wikipedia.org/api/rest_v1/project/random (One random article)
