The AMPRNet Portal has an associated API that allows the data and functionality of the Portal to be accessed programatically.
Version 1 of the API uses a RESTful design, accessible only via SSL (https://) to increase security.
All requests to the API require the client to authenticate by using Basic HTTP authentication, so you will need a username and password in order to access any part of the API, this can be obtained by registering for an account on the Portal.
Once you have an account, you can create your API Key (password) from the "Profile' menu link, in the "Security" section. The API username is the same username you used to login to the Portal via your web browser.
