## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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.md):

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

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

## CPF & CNPJ Validator - Brazil

Validate Brazilian CPF and CNPJ numbers instantly using the **official mathematical algorithm** (modulo 11 check digits). No external API calls, no API keys, no rate limits -- pure math, blazing fast.

### Why use this actor?

- **100% FREE** -- no API key, no subscription, no credits consumed on external services
- **Instant results** -- pure algorithm validation, processes 1000 documents in milliseconds
- **Offline algorithm** -- uses the same modulo-11 check digit math used by the Receita Federal
- **Auto-detection** -- automatically identifies CPF (11 digits) vs CNPJ (14 digits)
- **Formatted output** -- returns properly formatted numbers (XXX.XXX.XXX-XX / XX.XXX.XXX/XXXX-XX)
- **Batch support** -- validate up to 1000 documents in a single run

### Use cases

- **Form validation** -- verify CPF/CNPJ before submitting registration forms
- **KYC (Know Your Customer)** -- pre-validate documents during onboarding
- **Fraud prevention** -- detect obviously fake document numbers
- **Data cleaning** -- validate and format document columns in bulk datasets
- **E-commerce** -- validate buyer documents at checkout
- **Financial systems** -- ensure document integrity before processing transactions

### Input

You can provide documents in two ways:

#### Batch validation (recommended)
```json
{
    "documentos": [
        "529.982.247-25",
        "18236120000158",
        "111.111.111-11"
    ]
}
````

#### Single document

```json
{
    "documento": "529.982.247-25"
}
```

Numbers can include formatting characters (dots, dashes, slashes) or be digits only. The actor strips all non-digit characters before validation.

### Output

Each document produces one result in the dataset:

```json
{
    "documento": "529.982.247-25",
    "tipo": "CPF",
    "valido": true,
    "formatado": "529.982.247-25"
}
```

| Field | Description |
|-------|-------------|
| `documento` | The original number as you provided it |
| `tipo` | `CPF`, `CNPJ`, or `DESCONHECIDO` (wrong digit count) |
| `valido` | `true` if it passes the official check digit algorithm |
| `formatado` | Properly formatted number, or `null` if type is unknown |

### How the algorithm works

#### CPF (11 digits)

1. Strip non-digits, verify 11 digits remain
2. Reject known invalids (all same digit: 111.111.111-11, etc.)
3. Calculate first check digit using weights 10,9,8,...,2 on first 9 digits
4. Calculate second check digit using weights 11,10,9,...,2 on first 10 digits
5. Both check digits must match positions 10 and 11

#### CNPJ (14 digits)

1. Strip non-digits, verify 14 digits remain
2. Reject all-same-digit sequences
3. Calculate first check digit using weights 5,4,3,2,9,8,7,6,5,4,3,2 on first 12 digits
4. Calculate second check digit using weights 6,5,4,3,2,9,8,7,6,5,4,3,2 on first 13 digits

Both use modulo 11: if remainder < 2, check digit = 0; otherwise check digit = 11 - remainder.

### Limits

- Maximum **1000 documents** per run (if you send more, only the first 1000 are processed)
- No rate limiting needed since there are no external API calls

### Cost

This actor uses **minimal compute** since it performs only mathematical calculations. A typical run with 1000 documents costs a fraction of a cent in Apify platform fees.

# Actor input Schema

## `documentos` (type: `array`):

Array of CPF/CNPJ numbers to validate (up to 1000). Numbers can include formatting (dots, dashes, slashes) or be digits only.

## `documento` (type: `string`):

A single CPF or CNPJ number to validate. Use this field if you only need to check one document.

// Run the Actor and wait for it to finish
const run = await client.actor("cloway/cpf-cnpj-validator").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
