# Crawling services

External Importer supports multiple crawling services that automatically rotate IP addresses to prevent blocking and rate-limit issues.\
The currently supported services are:

* [Scrapingdog](https://www.keywordrush.com/go/scrapingdog)
* Scrapeowl.com
* [Scraperapi](https://keywordrush.com/go/scraperapi)
* Crawlbase
* Decodo

{% hint style="warning" %}
These services are paid, but each typically provides **around 1,000 free requests per month**.
{% endhint %}

### How to Route Requests Through a Scraping Service

#### 1. Add API Keys

1. Open **External Importer → Settings → Extractor**
2. Enter your API keys for the providers you want to use

You may enable one or multiple providers at the same time.

2. Enter a domain or pattern
3. Select the scraping provider
4. (Optional) Add additional parameters for the provider API

#### Pattern Examples

You can use **simple domain names** or advanced patterns:

* `example.com`
* `*.example.com` (any subdomain)
* `example.com/path/*` (match only specific URL paths)

#### Additional Parameters

Additional parameters are appended to the provider API request.\
Each provider uses its **own parameter names** and accepted values.

**ScraperAPI Parameters**

* `country_code=us` — Geotargeting
* `premium=true` — Premium residential/mobile IPs
* `ultra_premium=true` — Advanced bypass mechanism
* `render=true` — JavaScript rendering

**Scrapingdog Parameters**

* `country=de` — Geotargeting
* `premium=true` — Premium residential proxies
* `dynamic=true` — JavaScript rendering

**Combining Parameters**

Multiple parameters can be joined using `&`:

```
country_code=us&premium=true&render=true
```

### Rule Priority

Routing rules are evaluated **from top to bottom**.\
The **first rule that matches** a URL is selected, and the chosen provider will handle the request.
