Hello.
Currently i'm working on Web Application that uses Factorio API.
I noticed that none of the resources (links) listed on the pages below has a proper header ("Access-Control-Allow-Origin: *") that will allow you to use the CORS mechanism.

[Sanqui] Unable to use API using Web App
Re: [Sanqui] Unable to use API using Web App
This is not a bug. The API is intended for use by local scripts and programs, not other websites.
