# AgentQL Web Loader

> Precise web data extraction for agents

AgentQL Web Loader is a tool that scrapes a URL with a given AgentQL query or a Natural Language description of the data you want to scrape.
Create your own AgentQL API key [here](https://dev.agentql.com).

## Description

[AgentQL](https://agentql.com) provides structured data extraction from any web page using an [AgentQL query](https://docs.agentql.com/concepts/query-language) or a Natural Language prompt. AgentQL can be used across multiple languages and web pages without breaking over time and change.

## Installation

```bash theme={null}
agentstack tools add agentql
```

Set the environment variable in your project's `.env` file.

```env theme={null}
AGENTQL_API_KEY=...
```

## Arguments

The following parameters can be used to customize the `AgentQL Web Loader`'s behavior:

| Argument                       | Type      | Description                                                                                                                                                                                                       |
| :----------------------------- | :-------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **url**                        | `string`  | The URL of the web page you want to query.                                                                                                                                                                        |
| **query**                      | `string`  | *Optional*. The AgentQL query to execute. Learn more about [how to write an AgentQL query in the docs](https://docs.agentql.com/agentql-query).                                                                   |
| **prompt**                     | `string`  | *Optional*. A Natural Language description of the data to query the page for. AgentQL will infer the data’s structure from your prompt. **Note: You must define either a `query` or a `prompt` to use AgentQL.**  |
| **is\_stealth\_mode\_enabled** | `boolean` | Whether to enable experimental anti-bot evasion strategies. This feature may not work for all websites at all times. Data extraction may take longer to complete with this mode enabled. **Defaults to `False`.** |
