Modeling representational state transfer application programming interfaces by performing the following steps: (i) receiving REST schema information defining a REST schema; (ii) organizing into a non-cyclic object graph according to a hierarchy, a set of hypertext transport protocol (HTTP) endpoints, with each endpoint respectively including a portion of the REST application so that the set of HTTP endpoints are individually addressable by uniform resource locator (URL) addresses; and (iii) for each HTTP endpoint of the set of HTTP node types, assigning node types based on the REST schema.
