Drop-in replacement for DAWA. Change one line, add an API key — the rest works exactly as before. Autocomplete in ~70 ms (median).
Click through the six API areas and see TypeScript code + JSON responses in action. Copy the examples directly into your project.
Lightning-fast search across 2.7M addresses with fuzzy matching, prefix-cache, and bulk-receiver routing. Responses in the order users expect.

All prices are B2B and exclude VAT. 25% Danish VAT is added at checkout; EU businesses with a valid VAT number are billed at 0% (reverse charge). Yearly billing is charged as one payment (Basis 852 DKK/yr · Pro 2,676 DKK/yr).
Yes. We implement 100% of DAWA's REST API with the same paths, query parameters,
JSON fields, and address IDs (UUIDv4). Change the base URL to https://api.danadresse.dk
and add an X-Api-Key header. The rest works.
Directly from the Climate Data Agency's authoritative DAR (Danish Address Register) — the same data foundation DAWA had. We store our own copies and update them from Datafordeleren, independently of DAWA. Data is CC BY 4.0.
If your code still calls dawa.aws.dk, it now gets 410 Gone. Change
the base URL to api.danadresse.dk and add a key — and because address IDs are
identical between DAWA and DAR, you lose no references in your database. No other
code changes.
All servers operate in the EU (Germany). Address data is public (CC BY 4.0). We log API calls for 30 days pseudonymized for billing. No personal data leaves the EU. Read privacy policy.
Official, open-source (MIT): TypeScript (@danadresse/js),
Python (pip install danadresse). The REST API is DAWA-compatible,
so all existing DAWA clients (Go, PHP, Ruby, Java, .NET, R) also work.
Certainly. Write to hello@lynbro.dk or book a 15-minute demo call. We also assist with DAWA migration directly.
2,000 free address lookups per month. No credit card. No commitment. Drop-in DAWA replacement if you already have an integration.
