Quickstart guide

Go from nothing to your first address lookup in under 60 seconds. We'll walk you through the whole flow — create an account, get a key, make your first call.

100% compatible drop-in for the official DAWA. Change only the base URL — all your code, parsers and field names keep working unchanged.

curl "https://api.danskadresseapi.dk/dawa/autocomplete?q=Nørrebrogade" \
  -H "Authorization: Bearer $ADDR_KEY"

See the full comparison: /dawa vs v1

When you're done you can

Search 4.1M Danish addresses
Get fuzzy matching and typo tolerance
Fetch postal codes, municipalities, streets
Use from backend or browser

1. Create a free account

Go to . Just enter your email — we'll send a link to set a password. Or pick "Sign up with Google" if you prefer.

Tip

The Hobby plan is free forever: 1,000 calls per month, 3 keys, no credit card required. You don't need to upgrade until you actually need more.

2. Generate your first API key

Once signed in you land on the dashboard. Click <s>"New key"</s> in the "My keys" card. Give it a name (e.g. <code>production</code>) and pick <s>live — server-side</s>.

The key is shown <s>once</s> — copy it right away. It looks like this:

sk_live_AbCdEfGhIjKlMnOpQrStUv1234567890

Tip

<s>Important:</s> treat the key like a password. Store it in a .env file or your CI/CD secret manager — never in git or a frontend bundle. If it's compromised you can disable it and create a new one.

3. Make your first call

You're ready. Replace <code>YOUR_API_KEY</code> with your key and call the API. Pick the language you're using:

curl (terminal)

terminal

curl "https://api.danskadresseapi.dk/v1/autocomplete?q=N%C3%B8rrebrogade" \
  -H "Authorization: Bearer YOUR_API_KEY"

JavaScript / Node.js

search.js

1const r = await fetch(
2  'https://api.danskadresseapi.dk/v1/autocomplete?q=' + encodeURIComponent('Nørrebrogade'),
3  { headers: { Authorization: 'Bearer ' + process.env.ADDR_KEY } },
4);
5const results = await r.json();
6console.log(results[0]);
7// -> { type: TOK3, tekst: TOK4, ... }

4. What you get back

The response is a <s>flat array</s> — DAWA format. Each address has a top-level object with <code>type</code>, <code>tekst</code> etc. plus a <code>data</code> object with the full details:

response.json

 1[
 2  {
 3    "type": "adresse",
 4    "tekst": "Nørrebrogade 1, 2200 København N",
 5    "forslagstekst": "Nørrebrogade 1, 2200 København N",
 6    "caretpos": 33,
 7    "stormodtagerpostnr": false,
 8    "data": {
 9      "id": "70865c44-d570-44e7-a6f5-6f7c90add725",
10      "vejnavn": "Nørrebrogade",
11      "husnr": "1",
12      "etage": null,
13      "dør": null,
14      "postnr": "2200",
15      "postnrnavn": "København N",
16      "kommunekode": "0101",
17      "kommunenavn": "København",
18      "x": 12.5566,
19      "y": 55.6976,
20      "href": "https://api.danskadresseapi.dk/v1/adresser/70865c44-..."
21    }

<code>x</code> and <code>y</code> are WGS84 coordinates (longitude and latitude). <code>tekst</code> is the fully formatted address — perfect for displaying in autocomplete dropdowns.
