API CNPJ is a real-time REST API for looking up Brazilian company information, with its core capability being company profile queries by CNPJ. The page claims coverage of more than 70 million companies, 47 million corporate email addresses, 57 million phone numbers, and 18 million shareholder records. It can be used to analyze registration data, verify business partners, and generate sales leads.
In terms of functionality, it does more than return basic company information. It highlights fields such as sócios/QSA shareholder data, branches, phone numbers, emails, addresses, tax regime, CNAE, incorporation/opening date, and more. This makes it suitable for customer data enrichment, automatic form filling during account opening, and B2B lead filtering. The API uses a REST model with Bearer Token authentication. Example endpoints include /v1/cnpj/{cnpj} and /v1/status. The documentation provides cURL, PHP, Python, and JavaScript examples, plus a Playground, so developers should be able to make their first call fairly quickly. The page also mentions integration with ERP, CRM, internal systems, and n8n, while some plans support real-time Webhooks and PDF export.
Pricing is fairly clear: Starter is free with 15,000 requests/month; Basic is R$25/month with 80,000 requests/month; Profissional is R$49/month with 500,000 requests/month; and Enterprise is R$199/month with 2,000,000 requests/month. Annual billing is marked as 20% off. Based on the quotas, it offers strong value for teams that need Brazilian company data lookups. However, the main content does not disclose payment methods, contract terms, overage pricing, or refund policy.
The main advantages are its simple integration model, low entry price, generous plan quotas, and clear focus on integration scenarios such as CRM, ERP, and n8n. The documentation includes authentication, endpoints, and multilingual examples, making it beginner-friendly. The drawbacks are that it does not state whether it is open source or self-hostable, nor does it provide an official SDK, OpenAPI specification, complete error codes, or detailed response field definitions. Claims such as “100% updated” and “99.99% uptime” are not backed by verifiable SLA details on the page.
It is best suited to SaaS companies, cross-border trade businesses, financial risk control teams, sales operations teams, and master data teams serving the Brazilian market. If your business does not involve Brazilian CNPJ data, its value is limited. The main content does not provide information about access from China, so the status is unknown. Payment methods are also not specified, so teams in China should verify network connectivity, payment options, and data compliance requirements before purchasing. Alternatives include Receita Federal/Serpro data sources, BrasilAPI, CNPJ.ws, or a self-built Brazilian company data synchronization system.
