Google Trends API

Google allows users to view trends via Google Trends. On the daily page, there is an official RSS feed button. The feed can be easily parsed but if we inspect the page's source code, we find the following link which provides the data in JSON: https://trends.google.com/trends/trendingsearches/daily

Reddit API

Reddit has an amazing API. You can add .json to almost any page to get it's posts. For example, the top posts of r/popular: https://www.reddit.com/r/popular/top.json

GitHub doesn't have an official API, but it has a trending page which we can parse: https://github.com/trending

We can also get trending developers: https://github.com/trending/developers

Snapchat doesn't have an official API or a dedicated trending page, but they have a stories page and a map page: https://story.snapchat.com/ > https://map.snapchat.com/

The story page used to display popular and celebrity stories but now displayed random promotional ones. Older versions of this API used this as "trending" content because the map version wasn't readable. When Snapchat updated their site, they allowed the map to be read. The map showcases playlists of trending events.
