The Travel Intelligence API v1 follows the specification of the ‘profile’ link relation type, as specified by RFC6906:
$ curl -v https://demo.travel-intelligence.com/api/v1 HTTP/1.1 200 OK Link: <http://dev.travel-intelligence.com/profile>; rel="profile" Content-Type: application/json; charset=utf-8

In our case, it is the
URL of a textual representation of the constraints,
conventions and extensions on top of the JSONAPI
