The AMO API provides an interface to AMO for your web or other applications. The API supports REST and responses are returned in XML format.
Currently there are two components to the API:
This is the set of API calls used by the Firefox Add-ons manager. It is currently read only. It allows you to retrieve data about a single addon, groups of addons, or to search addons. This API does not require authentication or an API key for use.
The Bandwagon API allows you to interact with Add-ons Collections. This is a read/write API. It requires authentication using your existing AMO account.
