Integration, SDK and AI tools

Once you have a key, you can call the API from anything that can make HTTP requests.

• Direct HTTP — send your key in the Authorization header. See examples in the documentation.
• Playground → code — build the call in the [Playground](playground) and copy it as cURL or a code example.
• DAWA compatibility — already calling DAWA (api.dataforsyningen.dk)? Switch to the /dawa endpoint and migrate with no code changes. See the DAWA guide in the documentation.
• MCP server — use DanskAdresseAPI directly from AI tools like Claude and Cursor via the official MCP server.

Remember to use a live key on the server and a public key with a domain lock in the browser — see Live vs. public keys.
