Path parameters

NameTypeDescriptionExample

cuirequired string The company tax identification number, without the RO prefix (e.g. 6719278).

Query parameters

This route accepts no query parameters.

How it behaves

The primary CAEN (from the tax status) plus the activities authorised at ONRC. Codes appear in both revisions in which they are classified.
Note: the ONRC "primary activity" is empty across the whole registry, so the primary comes from the ANAF tax vector.

What it is for

Checking that a company is authorised for the activity you are contracting.
Classifying a customer portfolio by sector, on whichever CAEN revision you need.
Migrating codes between revisions, since the response gives both.

Error codes

Code	Slug	When it occurs
401	neautentificat	Token missing, invalid, expired or revoked.
403	feature_indisponibil	The current plan does not include the feature the route depends on.
404	negasit	The company with tax ID [{cui}] was not found.
422	validare	The route takes no parameters apart from `lang`: any other parameter returns 422 instead of being ignored.
429	cota_depasita	The plan's monthly quota has been exceeded (see `Retry-After`).

All errors share the same shape. eroare.cod is stable and is the value you should branch on in code — not the text in mesaj, which may change.
