I’m still not really sure what your question is,…
Both the https://bag.basisregistraties.overheid.nl/api/v1/verblijfsobjecten and https://bagviewer.kadaster.nl/ contain “house numbers” but the way they represent is different.
The bagviewer seems to give a response that is sorted, but the bag api doesn’t sorted the results.
This specific object seems to be a office building that contains multiple addresses, so there isn’t “one” single real address. A query on both endpoints/api’s will return multiple object with each there own address.
