What would you build with the whole country as a database?

A customer gives you one CNPJ. Your compliance team wants to know the whole group — and the people behind it. One call expands the corporate graph: Google Brasil alone resolves to 61 companies — payment institutions, holding companies, affiliates. Then flip it: search a person by name and see their CPF, their companies, and even whether they are a health professional with a council number.

Who pays: KYC teams at banks, exchanges and law firms — currently paying per-report agencies or spending days on manual registry digging.

"Every dental clinic in São Paulo with a phone number." Not a directory — the official registry, filterable by CNAE, state, size and status, with contact data, enriched in batch and exported to CSV your CRM can import tonight.

Who pays: agencies selling to dentists, equipment vendors, practice-management SaaS — they already buy leads from scrapers; you'd offer cleaner, fresher data.

A doctor joins your telemedicine platform. Is she really a doctor? Where does she practice? Does she own competing clinics? One name search returns her occupation (CBO), professional council and registration, CNS, every facility she works at — and her recovered CPF, which unlocks her business interests.

Who pays: insurance networks and telehealth platforms that credential thousands of providers — currently by phone calls and PDFs.

Your hospital needs gloves. What are other buyers actually paying, right now, and to whom? This is the actual price paid — dipirona 500mg at R$0.02 in recent purchases — with the real supplier, date and state. Then rank the suppliers of any item by their average price and see each distributor's full profile.

Who pays: hospital procurement teams benchmarking tenders; suppliers pricing competitively; medtech sales teams targeting buyers.

Before opening a clinic, answer: how many physiotherapists work in this state? Which occupations are scarce? What are real prices for the supplies I'll need? Workforce analytics + real prices turn a gut-feeling business plan into a data-backed one.

A consumer app that answers "what should this drug cost?" — the official maximum (CMED) by state, the cheapest presentation by active ingredient, and what the public system actually pays. Dipirona: 367 presentations, 90 brands, from R$4.04 official max down to R$0.02 in real purchases.

Who pays: price-comparison apps, pharmacy chains, PBM/cost engines, health plans checking markups.

Find every hospital in a state with type, coordinates, address and the company behind it — the national CNES registry crossed with the CNPJ record. An insurer building a network, or a telemedicine player routing patients, validates providers in one call instead of spreadsheets.

Who pays: insurers, network managers, telehealth routing, health travel.

KYC isn't a one-time check. Watch 1,000 CNPJs; get alerted when a customer's status, capital or shareholder count changes between monthly versions of the official registry. The versioned base is what makes this possible — nobody else keeps it.

Who pays: banks, payment companies, exchanges — regulators now require continuous monitoring, and vendors charge per CNPJ per month.

# the loop that powers it:
POST /v1/compliance/watchlist { "cnpjs": ["06990590000123", ...] }
GET  /v1/compliance/snapshot
GET  /v1/compliance/changes   # "what changed since last month?"

Validate the new alphanumeric CNPJ before your onboarding breaks. Quote in BRL with the official exchange rate. Price with the current tax tables. Check a customer company's health in one score. Everything a foreign software team needs to operate in Brazil — without learning Portuguese tax law.

Who pays: SaaS companies expanding to Brazil, ERPs, payment gateways, e-commerce platforms.
