There are two ways you can contribute, one is by adding more quotes. You can do this by adding the quotes to the JSON array which is available here.
Another way to contribute is if you find any bugs, you can report them by creating issues or better, fix them and open a pull request.
Other than fixing bugs, we can expose more endpoints on this API as per the requirements so feel free to open feature requests and let's discuss it there.
So go ahead, fork this repo and send PR to start contributing 🍻
