What this does not say

Quoted verbatim from the section’s warnings field, exactly as the API returns it. They are not translated: a translation would show something other than what your response actually contains.

Distance to the mapped marine limit only; whether the address lies below it (and so in possible marine-clay terrain) needs elevation, see marine_clay_possibility.
Straight-line EPSG:25833 distances from the address point to the feature; not travel distance. Source features are imported as published, with their own accuracy and update cadence; updated_at is our import time.

Fields

2 of 5 fields are value fields — the ones that decide whether a record actually says anything. The rest are context: identifiers, codes and timestamps. Fields marked “open” return values to anonymous callers; the rest require a key.
