DAWA has closed — here is the replacement

Migration

The migration, in two lines

Change where the request goes and add a header. Then unwrap the response one level where you read it.

# Before — DAWA, no key
curl "https://api.dataforsyningen.dk/autocomplete?q=vesterbrogade+1"

# After — Grundfast, bearer key, same idea
curl -H "Authorization: Bearer gf_live_..." \
  "https://api.grundfast.dk/v1/autocomplete?q=vesterbrogade+1"

Endpoint mapping

DAWA surface → Grundfast /v1

Every row is live today and requires a gf_live_ key. A call without a key answers 401.

Beyond the swap

What you gain by moving

A like-for-like swap is the floor, not the ceiling. DAWA stopped at the address.

• →The property behind the address. The same lookup can carry BBR buildings and units, cadastral parcels and ejerlav, joined on the BFE number.
• →Point-in-time reads. ?asOf=<date> and /historik return the address or property as it stood then (Scale plan and up).
• →Sets instead of loops. :batch resolves many in one call, async export jobs deliver CSV, NDJSON or GeoJSON, and signed webhooks push changes instead of you polling.

Sources

Where the date comes from

The closing date moved twice before it held, and both older dates are still circulating. Here is what the 1 October date rests on.

• Dataforsyningen: “Distribution af registre fra DAWA lukker” — updated 12 June 2026. The primary source for the final date.
• DAWA’s own documentation (archived copy) — the reference for the response shape the table above is held against. The documentation site closed together with the API.
