Getting started
Which surface should I choose?
A concrete choice based on what you need — not on what is newest.
Both surfaces reach the same address data. The difference is coverage and shape.
| You need to … | Choose |
|---|---|
| Migrate an integration that already calls DAWA | /dawa |
| Look up DAGI areas, place names, buildings, BBR or OIS | /dawa |
| Fetch the history of an address | /dawa |
| Build something new using only addresses, roads, postcodes and the cadastre | /v1 |
| Get soil contamination, noise, air quality, foreclosures or assessments | /v1 |
| Validate an address written as free text | /v1 |
In doubt? Choose /dawa.
It is fully covered and stable. /v1 is beta, and its surface may still change.
You can use both
The surfaces share your key and quota. Nothing stops you from calling /dawa for DAGI lookups and /v1 for soil contamination in the same integration — they reach the same database.
