Limitations

Data comes through a third-party provider
This tool reads Receita Federal CNPJ public-register records through ReceitaWS rather than directly from Receita Federal.
Rate limit is about 3 requests per minute
ReceitaWS limits these calls to roughly 3 per minute. Bursts can receive HTTP 429.
Personal-name data should not be used for direct marketing
The partners[] array carries personal names and roles for non-corporate partners. Per Brazilian LGPD, this data should not be reused for direct marketing without a separate lawful basis.
