How this service works
Search and segment active Brazilian companies by industry (CNAE, main OR secondary), location, size, age, share capital and name. Returns official registry data with business contact info. Ideal for B2B lead generation and market research on Brazil. Priced per page ($0.015). CNAE accepts 4-7 digit prefixes, masked or not (6201-5/01 = 6201501). MEI contact data is redacted (LGPD).
Output
A paginated JSON array of company records, each containing CNPJ (raw and formatted), legal name, trade name, company size classification, main CNAE activity code and description, secondary CNAE codes, full address (street, number, neighborhood, city, state, ZIP), phone numbers, email, registration date, share capital in BRL, and flags for MEI and Simples Nacional status. Also includes a next_cursor token for pagination, an estimated result count (may be capped), and the reference month of the underlying data dump.
Example use cases
B2B lead generation by sector
“Find me all active software companies (CNAE 6201500) registered in São Paulo state with up to 50 employees — I need their trade names, CNPJs, emails, and phone numbers for a sales outreach campaign.”
Market segmentation for a region
“I'm researching the food-service market in Recife, Pernambuco — can you pull a list of restaurants and food businesses there, sorted by company size, so I can see how the market is structured?”
Supplier discovery for procurement
“We're looking for certified logistics and transport companies (CNAE 4930202) in the state of Paraná — please search for active businesses of any size and return their legal names, CNPJs, and addresses.”

Endpoint
POSThttps://brdata.thomenz.me/companies/searchWhen to prefer
Use this endpoint when you need to search or segment across the full universe of ~28M active Brazilian companies by any combination of industry, location, or size — ideal for B2B prospecting, market research, and supplier discovery. Prefer this over the single-CNPJ lookup endpoints when you don't have a specific CNPJ and need to discover companies matching criteria at scale.
Side effects
- Invalid or unsupported filter parameters return a 400 error
- Expired or invalid cursor token causes pagination failure
- No matching companies found returns empty results array with count_estimate 0
- Rate limiting or payment failure (x402) blocks the request
- Overly broad queries may return capped estimates rather than exact counts
- Data freshness limited to the dump_reference_month; very recently registered companies may be absent
