401 — Missing or invalid API key

401 Unauthorized

You get 401 on /v1/* when the key is missing, malformed, or unrecognised.

Messages:

• "Manglende eller ugyldig API-nøgle" (Missing or invalid API key)
• "Ukendt eller deaktiveret API-nøgle." (Unknown or deactivated API key)

Fix:

1. Add the header Authorization: Bearer <key>.
2. Copy the key again from the dashboard (no whitespace, not truncated).
3. Key revoked? Create a new one under Dashboard → API keys.

curl -H "Authorization: Bearer live_xxx" \
  "https://api.danskadresseapi.dk/v1/adresser?q=rådhuspladsen%201%20københavn"

/dawa/* needs no key (anonymous up to 1,000 calls/day per IP) — so 401 only hits /v1/* or a wrong pub key (see "403 — Forbidden").
