new: type inference, upgrading to ESmodule and cleaning up

[ItamarShDev]

Description

In this PR, I have made the following changes:

1. Upgraded the ts file to ES6 and target to node.
2. The API will return JSON and throw an error on failure, to be compatible with best practices.
3. Added type inference for the api calls. if the conversion fails - the api returns a JSON object
4. cleaned up the code to handle errors easier

   Checklist

• [x] Code compiles correctly
• [x] Created tests which fail without the change (if applicable)
• [x] All lint and unit tests passing
• [x] Extended the README / documentation, if necessary
