Jikan is an unofficial PHP/REST API built for parsing data from MyAnimeList.net. It covers the features that the official MyAnimeList API lacks for developers.
It was originally developed as a script for fetching anime related details only and then evolved into an API.
Further more, it's capabilities were extended for developers as it became into a REST based API with it's own domain.
It's called "Jikan", because that means "time" in Japanese. So as a wordplay, Jikan is meant to save developers time from sidetracking their projects to create parsers.
Jikan is open source and available on Packagist. That is, it can be simply required in PHP projects.
composer require jikan-me/jikan
