Batch lookup

POST https://firmatal.dk/api/batch

Up to 100 registration numbers per request, one quota unit per number. All-or-nothing on capacity: if the batch would blow past your daily cap, none of it runs and you get a 429 instead of a partial answer.

curl -X POST 'https://firmatal.dk/api/batch' \
  -H 'Authorization: Bearer cvr_your_token_here' \
  -H 'Content-Type: application/json' \
  -d '{
    "country": "dk",
    "queries": ["12345678", "22222222", "99999999"]
  }'

Response returns one entry per query in the order sent, each either with company or with an error code (NOT_FOUND, INVALID_VAT). quota_used reflects what the batch cost.
