# Kortlagt jordforurening (V1/V2) on one jordstykke

`GET /v1/jord/kortlaegning/matrikel/{ejerlavskode}/{matrikelnr}`

## Request

- Base URL: `https://api.grundfast.dk`
- URL: `https://api.grundfast.dk/v1/jord/kortlaegning/matrikel/{ejerlavskode}/{matrikelnr}`
- Auth: one of:
  - HTTP bearer
  - API key in query parameter `token`

Two independent tests, both reported per flade: `registreret_paa_matriklen` (the region listed this matrikel on the flade) and `overlap` (the share of the parcel outline the flade covers, measured on a point grid). A flade is included when either holds. `rumlig_kontrol: false` means the outline could not be resolved and only the lists were read — such an answer is only ever a yes. `attest_url` is the official jordforureningsattest for the jordstykke, which exists whether or not it is kortlagt.

## Path parameters

- `ejerlavskode` integer, required
- `matrikelnr` string, required

## Other responses

- `400`: Error
- `401`: Error
- `404`: Matriklen has no gældende jordstykke with this key.
- `429`: Error
- `502`: A kortlægning layer could not be read, OR the register lists nothing on the matrikel and the parcel outline could not be resolved to check it spatially. A "not kortlagt" answer is never served unchecked.
- `503`: Kortlægning source (or, for a "not kortlagt" answer, the Matriklen outline source) not configured for this deployment; /v1/demo/jord/kortlaegning/matrikel works offline.
