I’m currently creating a python script to pull auction house data. I’ve used the realm index feature and pulled Kazzak-EU (admittedly I found its id on a forum first). This works fine.
I’ve tested a few other servers, Arathor, Hellfire, etc and they are working fine.
The realm index gave Silvermoon’s id as 549 but when I run it (even through the sample pull in the browser here) it returns a 404 not found. The link shows a URL with /connected-realm/549 in it, but as far as I’m aware Silvermoon isn’t a connected realm.
