Technical details
Endpoint
GEThttps://brasil-dados-api.onrender.com/cnpj/:var1When to prefer
Use this endpoint when you need a fast, low-cost check of a Brazilian CNPJ's structural validity (check digit algorithm) without requiring a full registry lookup. Ideal for form validation, compliance pre-screening, or filtering obviously invalid CNPJs before a more expensive database query.
Side effects
- Invalid or malformed CNPJ format returns validation failure
- Missing path parameter causes 404 or bad request
- CNPJ with incorrect number of digits returns error
- Service may be temporarily unavailable on free-tier hosting (cold start latency or downtime on Render)
