<p>This is a simple server list API for Stormworks. The following endpoints are available:<br>
|
||||
/check?address=IP:PORT<br>
|
||||
/serverList<br>
|
||||
/docs<br>
|
||||
/robots.txt<br>
|
||||
<br>
|
||||
/serverList takes the following optional parameters:<br>
|
||||
?uptodate - Filters out servers that are not running the latest version<br>
|
||||
?outdated - Filters out servers that are running the latest version<br>
|
||||
?version=v1.10.0 - Filters servers by version<br>
|
||||
?dlc=1|2|3 - Filters servers by DLC<br>
|
