Getting started
No registration. The first 200 calls per day per IP address are open, and map tiles never count against the quota.
Three calls
1. Where is this place?
curl 'https://api.kart-api.se/v1/geocode?q=Fridhem&limit=3'Read spridning (spread) before you read results: Fridhem exists in hundreds of municipalities, and the three hits you got are not the whole truth. Add &kommunkod=0562 when you know which municipality you mean.
2. Which municipality is this point in?
curl 'https://api.kart-api.se/v1/kommun/lookup?lat=58.705&lon=15.77'3. How high is it?
curl 'https://api.kart-api.se/v1/hojd?lat=58.705&lon=15.77'What exists

The full contract with every field: openapi.json. That file is the source; this page is a shortcut.
What is NOT here, and why
Cadastral boundaries, building footprints, the national address register and aircraft positions exist in the platform but are not part of the public API. Lantmäteriet's terms for the first three bind the processing to the purpose we applied for — journalism — and an open API is somebody else's purpose. Aircraft positions are ODbL-licensed in a way that makes a JSON endpoint a database in its own right.
We would rather write it out than let you discover a gap. If you need one of them, get in touch.
Limits
- Sweden. Outside the country the lookups answer nothing rather than guess.
- Rate: 200 calls per day without a key, 10,000 per month with one. See authentication.
- Attribution is required. Every response carries the lines you must display. See attribution.
