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	Company [{cui}] 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.
