Overpass turbo: Finding capitals of relations

Question

I'm looking for a way to grab the capital of a relation, for which I have the OSM ID.

I can print out the relation like this:

[out:json];
relation(8654);
out body;

and I have the data (node with "role": "admin_centre"), however I would then need to parse the JSON myself which is:

a waste of bandwidth for everyone involved.
needless processing on my side
I would then need to make another query to OSM to get data for the node

What I need is the data found here https://www.openstreetmap.org/node/26761400 , but in JSON format and through the API. I don't have the OSM ID of the node, only the relation.

So I would like to know if there is a way to get just the node data.

Thanks!

You need a recurse filter:

[out:json];
relation(8654);
node(r:"admin_centre");
out body;

Here's a demo.

Perfect, thank you! I had seen the recurse filter in the docs but did not understand it.
