## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Mercado Livre Brasil Scraper

**Public Mercado Livre Brazil product search → structured listings.**

Colete anúncios públicos de [mercadolivre.com.br](https://www.mercadolivre.com.br) para monitoramento de preço, sortimento e concorrência — sem conta de vendedor.

- Tenta primeiro o JSON público `api.mercadolibre.com/sites/MLB/search` (desde ~2025 muitos IPs recebem 403).
- Fallback: HTML de `lista.mercadolivre.com.br/{termo}` (cards `ui-search` / `poly-component` ou `__PRELOADED_STATE__`).
- Filtros: palavra-chave, ordenação, faixa de preço em R$, vendedor opcional.
- Campos: título, preço, preço original/desconto, parcelas, nota, avaliações, vendedor, frete, id/URL, condição.
- HTTP primeiro. Verificação de conta / challenge **encerra o run** (fail closed).

### Fonte

`GET https://api.mercadolibre.com/sites/MLB/search?q=notebook`

`https://lista.mercadolivre.com.br/notebook`

Não usamos a API de vendedor autenticada nem cookies de conta.

**Apify Console → Use Apify Proxy → RESIDENTIAL → country BR.** Sem isso, `MLB/search` devolve 403 e a lista redireciona para `account-verification`. SessionPool rotaciona o IP; challenge persistente = fail closed.

### Amostra de saída

Exemplo ilustrativo no formato do JSON público (valores mudam o tempo todo).

```json
{
  "id": "MLB3678901234",
  "title": "Notebook 15 i5 16GB 512GB",
  "price": 2899.9,
  "originalPrice": 3499,
  "discountPercent": 17,
  "installments": "10x R$ 289.99",
  "rating": 4.8,
  "reviews": 1240,
  "seller": "LOJA OFICIAL EXEMPLO",
  "freeShipping": true,
  "condition": "new",
  "url": "https://produto.mercadolivre.com.br/MLB-3678901234"
}
```

### Configuração

| Campo | Default | Descrição |
| --- | --- | --- |
| `keyword` | notebook | Busca |
| `sort` | relevance | price\_asc / price\_desc / newest |
| `minPrice` / `maxPrice` | — | R$ |
| `seller` | — | Nickname (filtro local) |
| `sellerId` | — | ID numérico na API |
| `maxItems` | 40 | Teto 5.000 |
| `searchUrl` | — | Cola uma URL de resultados |
| `proxyConfiguration` | — | Se houver redirect de verificação |

### PPE

Evento `dataset-item`: **US$ 3,00 / 1.000 anúncios** sugerido.

### LGPD

Anúncios e nicknames de loja são públicos. Não extraímos mensagens, CPF de compradores nem dados de conta.

### Desenvolvimento

```bash
cd actors/mercado-livre-brasil-scraper
npm install && npm test && npm run build
apify run
```

# Actor input Schema

## `keyword` (type: `string`):

Termo de busca, como na barra do Mercado Livre.

## `sort` (type: `string`):

relevance (padrão do site), preço ou mais recentes.

## `minPrice` (type: `integer`):

Filtro em reais.

## `maxPrice` (type: `integer`):

Filtro em reais.

## `seller` (type: `string`):

Filtro local pelo nickname público do vendedor, se o HTML/JSON trouxer o campo.

## `sellerId` (type: `string`):

Quando a API MLB/search responder, aplica seller\_id. No HTML vira filtro local se o id aparecer.

## `maxItems` (type: `integer`):

Limite rígido (teto 5.000).

## `searchUrl` (type: `string`):

URL pública lista.mercadolivre.com.br ou mercadolivre.com.br. Sobrescreve keyword/sort.

## `useBrowser` (type: `boolean`):

Playwright só abre a lista pública. Verificação de conta persistente = fail closed.

## `proxyConfiguration` (type: `object`):

Padrão em produção: Apify RESIDENTIAL + país BR. Sem isso a API MLB e a lista caem em 403 / account-verification.

## Actor input object example

```json
{
  "keyword": "notebook",
  "sort": "relevance",
  "maxItems": 20,
  "useBrowser": true,
  "proxyConfiguration": {
    "useApifyProxy": true,
    "apifyProxyGroups": [
      "RESIDENTIAL"
    ]
  }
}
```

# Actor output Schema

## `results` (type: `string`):

// 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();

## CLI example

```bash
echo '{
  "keyword": "notebook",
  "maxItems": 20,
  "proxyConfiguration": {
    "useApifyProxy": true,
    "apifyProxyGroups": [
      "RESIDENTIAL"
    ]
  }
}' |
apify call national_scrim/mercado-livre-brasil-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,national_scrim/mercado-livre-brasil-scraper"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
