One approach Assuming you're using the overpass turbo wizard, you will not get any kind of bounding box information in your Overpass API result.
Although this is not really documented, a feature called [global bounding box][1] might come in handy in your case: it will add that bounding box detail to use a your response you didn't get so called global bbox, far. Simply add `[bbox:{{bbox}}]` to your query like shown demonstrated in the following query: http://overpass-turbo.eu/s/bC5
This will add your bbox selection Bounding box details are now automatically added to the Overpass response with 4 digits precision:
response:
"bounds": {
"minlat": 41.8926,
"minlon": 12.4936,
"maxlat": 41.8932,
"maxlon": 12.4953
},
If you're using XML output mode instead, Overpass API will produce a slightly different format:
<bounds minlat="41.8912" minlon="12.4922" maxlat="41.8954" maxlon="12.499"/>
