[Feat]: Endpoint as a data source.

[rjamesnw]

Is your feature request related to a problem? Please describe.
For the app I'm planning to build I'll need to provide an API to the functionality in that app. I don't see any way to do that in lowcoder.

Describe the solution you'd like
I think a valuable feature would be to enable API endpoints for advanced users of an app (typically public focused). The endpoint would use a similar UI as the query, where you define the query parameters expected for GET, or posted variables for POST, then define what the output would be, like the module outputs. From the output details you could even create a swagger doc (or have this as another data source you configure with a list of those endpoints you allow access to). I realize for this to work as expected you would also need to support shared scripts as well, then people have the option to easily create a script with expected parameters and outputs, then you can select them for endpoints, or import into apps (code reuse).

Describe alternatives you've considered
Using some other app for the API, but I don't want to recode all the business logic between two environments.
