Patent attributes
An example system includes persistent storage and a discovery application configured to perform operations including obtaining a uniform resource locator (URL) that addresses a function of an application programming interface (API) provided by a remote computing system of remote computing systems that provide computing resources. The function returns attributes of computing resources specified by the URL. The operations additionally include generating (i) a system-specific portion of a request that invokes execution of the function and (ii) a system-invariant portion of the request. The system-specific portion adheres to first rules adopted by the remote computing system for interacting with the API. The system-invariant portion adheres to second rules adopted by each of the remote computing systems for interacting with respective APIs thereof. The operations yet further include transmitting the request to the remote computing system, receiving therefrom a response containing the attributes, and storing, in the persistent storage, the attributes.
