An API for accessing information about resources and authors from SpigotMC in JSON format. Inspired by BukGet, a similar project which used to provide the same service for the Bukkit plugin marketplace. It periodically scrapes the SpigotMC website for new resource updates and allows users to register webhooks for fast updates. Many server plugins use the API to check if new versions are available, with some providing auto-update functionality.
SpigotMC has since added their own API which exposes some basic information, but Spiget continues to provide the most complete snapshot of available data.
