A module can now bring several API classes.
By example, thirdparty module can have api_thirdparty.class.php for thirdparty and api_contact.class.php for contacts.

Classes must be named <Object>API (ie ThirdpartyApi or ContactApi)

API authentication mechanism is supposed to be working with internal or external users

Now we can use tag '@class' into PHPDoc block of method or class.

By example: @class  DolibarrApiAccess {@requires user,external}

One key is stored by user when login API method is called. Each API request must have api_key parameter

Work in progress !
