Yes, but it will not give you anything new: The Wolfram Engine provides full access to the Wolfram Language (just like Mathematica) via command line access and executing Wolfram Language scripts.

Wolfram|Alpha and Wolfram Language are two completely different things:

Wolfram|Alpha is a natural language computational engine which takes queries and computes custom answers based on back-end knowledge databases and a large amount of Wolfram Language algorithms.

Wolfram Language is a computational (programming) language. There is a good 'fast introduction' for it here:

http://www.wolfram.com/language/fast-introduction-for-progra...

The full reference documentation for the Wolfram Language is located here:

https://reference.wolfram.com/language/

(It's extremely well-documented with extensive examples for every function).

There is this:

Additionally many IDEs have support for Wolfram Language, e.g.

Eclipse: https://www.wolfram.com/workbench/ IntelliJ IDEA: https://wlplugin.halirutan.de/

There is a Jupyter notebook interface for the Wolfram Language:

Additionally, many IDEs support Wolfram Language for syntax coloring, command completion, contextual help, etc.:

It's used in more places than you'd think, e.g. Alexa:
