BBOX of a relation by its ID, API to obtan it

Question

I have the ID of the relation, and I need a API that returns its boundary box.

Example: the relation 298204, openstreetmap.org/relation/298204... Where its boundary box?

PS: I need BBOX in standard format (ex. to use in Overpass).

Accepted Answer

Finding the bounding box

relation   (298204) ;
out  bb ;

gives the information you want (but not quite in the right format. A bit if editing will get it.

bounds minlat="-25.4832679" minlon="-53.1090000" maxlat="-19.7823272" maxlon="-44.1610000"

Using a relation within Overpass

Assuming you want to do the query mentioned in Best way to retrieve a CSV table from Overpass , the following query uses the area defined by the relation, rather than a bounding box.

[out:csv(::id,::user,::type,wikidata,name,place, boundary)] ;
relation   (298204) -> .c ;
.c map_to_area -> .myarea ;
( 
  node (area.myarea)  [place] [wikidata] ;
  relation  (area.myarea) [boundary] [wikidata];  
);
out meta ;

In a bit more detail

Load the relation into set c
Create an area from set c.
run the query - (area.myarea) restricts it to this area
