Programmer input in a programming language is received, the programmer input including i) first specification data specifying one or more parameters to be passed to an application programming interface (API), and ii) second specification data that specifies a function to be performed by the API. The programmer input is evaluated to generate an API object that is configured, when executed, to perform the specified function using the one or more parameters. Evaluating the programmer input includes evaluating the first specification data to generate the API object such that the API object is configured to receive the one or more parameters.
