In Holland we use a tool offered by the government to get the height data based of NAP (Nieuw Amsterdams Peil), the tool works but it's kind of clunky and inefficient.

nap. It's in dutch but if you zoom in on the map you will see the locations of these "bolts" and there is some data attach to each of them. Now I am wondering if I could make a HTTP GET request to get access to this data. For example, I could make an app where the user inputs a address or coordinate and it would automatically generate a map and a list with these height bolts and there data.
There are sites that seem to supply all kinds of geo data but I am having trouble finding these bolts with "exact" height data. http://geodata.nationaalgeoregister.nl/bag/wfs?service=WFS&request=GetCapabilities&. Opengis is more of a international organization and they also provide an API to access data in JSON or XML but I'm not sure they have data about these specific height bolts in The Netherlands. http://schemas.opengis.net/gml/3.1.1/base/gmlBase.xsd
How can I get an X amount of these bolts with height in XML format through a
HTTP GET Request for a random location.
edit It seems the following should yield the server capabilities of the CKAN API: https://geodata.nationaalgeoregister.nl/napinfo/wfs?request=GetCapabilities but it results in a error.
The following URL does yield a abstract feature which is what I am actually looking to "GET" from a specific measuring point: https://geodata.nationaalgeoregister.nl/napinfo/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&
That link tells me it is possible to somehow access specific measurement bolts and show me the height, locations in the wall, the name, date of measurement, etc. I just have no idea how to create a proper GET request to get these objects near a address or coordinate.
