  description: Imgur is an online image and album hosting platform. The Imgur API (v3) is a RESTful HTTP/JSON API that exposes the platform — uploading, retrieving, voting, commenting, galleries, accounts, and tags. Anonymous reads/writes are supported with a Client-ID, and per-user actions require OAuth2 access tokens.
