Mod portal API

Category: Internal API

The Mod Portal API is used to both browse and download all mods available on the official Factorio mod portal. Using the API does not require any kind of authentication or account information and can be viewed simply by following the URLs below in any web browser.

https://mods.factorio.com/api/mods

More detailed information about a particular mod can be obtained by retrieving the following URL, where {name} is the mod's name field in the result object.

https://mods.factorio.com/api/mods/{name}

To get even more information about a mod, you can use the following URL.

https://mods.factorio.com/api/mods/{name}/full

Downloading Mods

You can get the full url by appending the download_url to mods.factorio.com, but if you're not authenticated, you will be redirected to mods.factorio.com/login. Logging in to that would give you access to the file. Fortunately, there's a better way to do this. Simply adding username and token parameters to the download url will prevent the redirecting and let you download the file immediately. The token can be acquired from a json file called "player-data.json", located in the User Data directory (see Application_directory#User_data_directory). You can also get the token by using the Web Authentication API.

Example usage: https://mods.factorio.com/{download_url}?username={username}&token={token}
