Since there is no API call to get rendered guild emblems you need to render them yourself. In this case you need to make use of the base background and emblems
found in the wiki http://wiki.guildwars2.com/wiki/Gallery_of_guild_emblems

What are the rules on using them ?
Or did I miss an API call to get the base images through the API ?

There’s no way to get the guild emblems yet but to extract them from the gw2.dat. Dr Ishmael did that before, have a look at this post: https://forum-en.guildwars2.com/forum/community/api/API-Suggestion-Guilds/2151144
We also don’t know exactly how to postprocess the images so that we can build 1:1 guild emblems, see the latest not-so-bad result i got over here: https://forum-en.guildwars2.com/forum/community/api/API-Suggestion-Guilds/2155863
For some code have a look at this: https://github.com/codemasher/gw2api-tools/blob/master/examples/gw2emblems.php
