# What is ZOO-API ?

ZOO-API is a server-side JavaScript library designed to make the WPS Process creation and chaining easier. It works on the server-side using the Mozilla foundation JavaScript engine, SpiderMonkey. It uses a Proj4js adaptation for server-side reprojection. It also allows to easily convert vector formats (such as GML, KML, GeoJSON, etc). The API lets you orchestrate WPS services simply and offers the ability to add logic and controls in the WPS chaining.
