2//! API Wrapper for the [TASVideos API](https://demo.tasvideos.org/api/).
3//! 
4//! This crate provides synchronous functions for each supported endpoint of the API.
5//! 
6//! All requests can be used without an API key, however, the [`USER_AGENT`] string should be set
7//! before making any requests.
