Yes correct, different APIs though might show depending on the version currently running on the node you are accessing.
Syncad has been down for few hours today, should be brought back up soon, blocktrades team manages this node and they are looking into it.
You can find a list of publicly available nodes under https://beacon.peakd.com
The newer the version, the newer the set of APIs it provides
