It's been around 5 years since Polygon API was released by MikeMirzayanov. However, at the moment, it does not have any official API wrapper for Go (or any other language, for that matter).

Since I needed to work with the API for a specific use-case, I decided to write the library myself. The Go package is published on Github, you can find the detailed package documentation for the library on the Go Package Website and a good number of examples to get familiar with the API and the packages on Github. You can use this in conjunction with Cobra to create command line applications tailored to your needs.

At the moment, it has all the custom objects mentioned in the API documentation, and all but one API method.

Feedback, suggestions and Pull requests are welcome.
