It seems that Stackby has a Developer API, which would mean it might be able to be used as a 'data store' or 'headless CMS' for a frontend website/web app. Is that correct? If that is the case, are there any limitations? - eg., is the API capable of accessing all functions, including querying and updating data? Is there a limit on the number of API calls?

I wanted to check your Developer API documentation, but at the moment the link you have on your site's footer is giving a '404' error...
