How this service works
Validate up to 25 Brazilian CNPJ company tax IDs in a single call. Cheaper per-item than individual requests — built for bulk/KYB workflows.
Output
Returns a validation result for each CNPJ in the batch indicating whether the check digits are mathematically correct and the number is structurally valid, without performing any live registry lookup.
Example use cases
Example prompt
“Can you validate these Brazilian CNPJ company tax IDs for me and tell me which ones have valid check digits: 11.222.333/0001-81 and 45.678.901/0002-10?”
Technical details
Endpoint
GEThttps://brasil-dados-api.onrender.com/cnpj/batchWhen to prefer
Use this endpoint when you need to quickly verify the mathematical validity of one or more Brazilian CNPJ numbers via check-digit validation before processing them further. It is ideal for pre-screening bulk data or form inputs where you need a cheap, fast structural check without a full registry lookup. Choose the full CNPJ dossier endpoint if you also need legal name, registration status, or partner information.
Side effects
- Missing or malformed CNPJ input returns an error
- Non-numeric or incorrectly formatted CNPJ strings may cause validation errors
- Rate limiting or payment failure returns 402 or 429
- Render cold-start latency may cause occasional timeouts
