## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Brazilian Companies Finder — by CNAE & State (CNPJ Discovery)

Pick an economic activity (CNAE) and a state — get back **every active Brazilian company that matches**: CNPJ, legal name, trade name, city, size and opening date. Search across **27.8 million active companies** indexed from the official Federal Revenue (Receita Federal) open dataset. No scraping, no login, no API key.

![Cover](https://empresas-por-cnae.vercel.app/covers/cnpj-discovery.png)

Also searchable in Portuguese: *lista de empresas por CNAE e estado, empresas ativas por segmento, prospecção B2B com dados da Receita Federal*.

**This is the discovery layer**: it finds the companies. Pair it with [CNPJ Lookup](https://apify.com/gangary/cnpj-lookup) (full registry data per company) and the [Lead Enricher & ICP Scorer](https://apify.com/gangary/lead-enricher-icp) (verify and score before outreach) for a complete prospecting pipeline.

### Input example

Dental clinics in São Paulo and Minas Gerais, up to 500 results:

```json
{
  "cnae": "8630-5/04",
  "ufs": ["SP", "MG"],
  "limit": 500
}
````

- `cnae` accepts the full code (`8630-5/04`), digits only (`8630504`) or a **prefix** (`8630` = every outpatient activity, `86` = all of healthcare).
- `municipio` narrows to one city (accent-insensitive: `"Sao Paulo"` works).
- `porte` filters by declared company size (`MEI/micro`, `small`, `other`).
- `offset` + `limit` paginate a big segment across cheap runs.

### Output example

```json
{
  "cnpj": "12345678000195",
  "cnpj_formatado": "12.345.678/0001-95",
  "razao_social": "CLINICA ODONTOLOGICA EXEMPLO LTDA",
  "nome_fantasia": "Sorriso Exemplo",
  "cnae_principal": "8630504",
  "cnae_formatado": "8630-5/04",
  "municipio": "SAO PAULO",
  "uf": "SP",
  "porte": "MICRO EMPRESA",
  "data_abertura": "2019-03-14",
  "tem_email": true,
  "tem_telefone": true
}
```

### Output fields

| Field | Description |
|---|---|
| `cnpj` / `cnpj_formatado` | The company's tax ID, digits-only and formatted. |
| `razao_social` | Exact legal name from the federal registry (unmodified). |
| `nome_fantasia` | Trade name, when declared. |
| `cnae_principal` | Primary economic activity code (what the company actually does). |
| `municipio` / `uf` | City and state of the establishment. |
| `porte` | Declared size (MEI/micro, small, other). |
| `data_abertura` | Opening date (YYYY-MM-DD). |
| `tem_email` / `tem_telefone` | Whether the registry has an email/phone on file for this company — useful to estimate contactability before running [CNPJ Lookup](https://apify.com/gangary/cnpj-lookup). |

### Use cases

- **Build a prospecting list by niche + region** — every active dental clinic in SP, every trucking company in the South, every software house in your city
- **Size a market (TAM)** — how many active companies exist per CNAE per state, with zero sampling bias (it's the full registry)
- **Feed your sales pipeline** — Discovery finds them → [CNPJ Lookup](https://apify.com/gangary/cnpj-lookup) pulls addresses, partners and contacts → [Lead Enricher](https://apify.com/gangary/lead-enricher-icp) verifies and scores them
- **Territory planning** — split a segment by city/size before assigning reps

### Pricing (Pay per event)

| Event | When | Price |
|---|---|---|
| `actor-start` | once per run | $0.005 |
| `company-found` | per company returned | $0.002 |

A 500-company list costs $0.005 + 500 × $0.002 = **$1.005**. A 5,000-company segment costs **$10.005**. Runs that find nothing only pay the start fee.

### Where the data comes from

The official **CNPJ open dataset published by Receita Federal** (Brazil's Federal Revenue), rebuilt into a fast index **every month** — you always query the latest published registry snapshot, with only **active** (situação ATIVA) establishments included.

### Is this compliant?

Yes — the CNPJ registry is **public information** that Receita Federal itself publishes as open data. No scraping, no logins, no private or behind-auth data. LGPD note: these are company registry records, published officially for public consultation.

### Limitations

- Data is a **monthly snapshot** of the official registry — a company opened yesterday appears after the next monthly rebuild.
- Returns registry firmographics, **not contact details** — `tem_email`/`tem_telefone` tell you they exist; [CNPJ Lookup](https://apify.com/gangary/cnpj-lookup) retrieves them per company.
- Filters use the **primary** CNAE (secondary activities are not indexed).
- Only **active** companies — closed (BAIXADA) or suspended ones are excluded by design.

### From the same maker

- **[CNPJ Lookup — Brazilian Company Registry Data](https://apify.com/gangary/cnpj-lookup)** — full official record per CNPJ: status, address, partners, capital, phone and email when on file.
- **[Lead Enricher & ICP Scorer](https://apify.com/gangary/lead-enricher-icp)** — clean, verify, dedupe and score any lead list 0–100 against your ideal customer profile.
