# /cvrapi/api

`POST /cvrapi/api`

## Request

- Base URL: `https://api.companydata.dk` (the document declares no server; this is the origin it was published from)
- URL: `https://api.companydata.dk/cvrapi/api`
- Auth: none declared

Look up one Danish company in cvrapi.dk's version 6 format.

A drop-in replacement for `https://cvrapi.dk/api`: change the base URL to
`https://api.companydata.dk/cvrapi/api` and keep your parameters.

**Parameters** (query string, or form fields on POST):
- `vat`: CVR number. `produ`: P-number (answers with the production unit
  in the company shape). `phone`: phone number. `name`: best match for
  a company name, active companies first. `search`: a CVR number,
  P-number or name. One is used, in that order.
- `country`: `dk` (the default; only Danish companies are served).
- `format`: `json` (default) or `xml`. `callback`: JSONP function name.
- `token`: a companydata.dk API key (`sk_...`), also accepted as
  `Authorization: Bearer`.

**Access:** everyone gets 50 lookups a day (per IP without a key, per
account with one). A companydata.dk API key adds its monthly API quota
on top: a free account 1,000 a month, Pro 300,000.

**Errors** keep cvrapi.dk's shape, e.g. HTTP 404
`{"error":"NOT_FOUND","t":0,"version":6}`. Codes: NOT_FOUND,
QUOTA_EXCEEDED (429), INVALID_VAT, NO_SEARCH, UNSUPPORTED_COUNTRY (400),
INVALID_TOKEN (401).

## Response `200`

The company in cvrapi.dk's version 6 format

## Other responses

- `404`: Not found: {"error":"NOT_FOUND","t":0,"version":6}
- `429`: QUOTA_EXCEEDED: keyless ceiling or the key's quota reached

## Changes

- **2026-10-19** `1cc6c361ae64`: 1 info
  - api operation id `cvrapi_lookup_cvrapi_api_get` removed and replaced with `cvrapi_lookup_cvrapi_api_post`
