Do you know any good websites for current cyber threats through API?

I need a website for current cyber threats for my Android-Java project, like the website https://openweathermap.org. In this site you can request the current weather via HTTP Request and you recieve it as a JSON file. I would like to use a similar website but instead of weather current cyber threats. I tried to search the web for a while but I couldn't find any relevant website.

Thanks in advance.
