Reach out if you are certain this is a error. https://cvrapi.dk/contact\",\"ip\":\"<redacted>\"}\n```\nReproduced twice, same org number, ~30 seconds apart — not a transient rate-limit edge.\n\n```\ncurl -A \"python-requests/2.31\" \"https://cvrapi.dk/api?search=22756214&country=dk\"\n```\n(same org number, immediately after the 403 above) → `HTTP 200`:\n```json\n{\"vat\":22756214,\"name\":\"A.P.

The service silently distinguishes \"no custom User-Agent\nsent\" from \"too many requests\": the former is answered with a quota-shaped 403 that\ngives no indication the actual cause is the UA string, not request volume. An agent\nretrying with backoff on this 403 would loop forever; the fix is unrelated to pacing.\n\nSeparately, a nonexistent CVR number (`00000000`) with a working custom UA returns\n**HTTP 200** `{\"error\":\"NOT_FOUND\",\"t\":0,\"version\":6}` — not-found is 200, only the\nUA-gate failure is a 403.\n\nHow observed: 2026-10-05T06:09Z–06:10Z, curl 8, GET only.
