An API (Application Programming Interface) is a service allowing developers to create their own custom applications which interact with Future Invaders' website.
If you did not already know what an API is, then this part of the website is most likely not for you. It will only be of interest for people who have technical skills.
Every route's URL begins with https://futureinvaders.com/api/
Documentation for all routes can be found through the dropdown menu at the top of the page.
The API is read-only: you can use it to fetch data, but not to interact with the website.
Using the API does not require authentication. There are no access restrictions and no rate limiting.
The API is not versioned. This means if a breaking change happens, the previous way of interacting with the API will disappear, and you will need to update your applications accordingly. Although the API is designed so that breaking changes should ideally never need to happen, advance warnings will be given before any future API breaking changes on IRC and Discord.
