## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with WebCrawlerAPI MCP or direct API to crawl websites, scrape pages, monitor feeds, and extract web data through natural language.

## Summary

WebCrawlerAPI is a unified API for crawling websites, scraping pages, running AI web agents, and monitoring website feeds.
It helps you extract fresh web data without building crawler infrastructure yourself.

## Categories

- data & analytics

## Toolkit Details

- Tools: 10

## Images

- Logo: https://logos.composio.dev/api/webcrawlerapi

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for WebCrawlerAPI.
  - Setup:
    - Configure Api Key credentials for WebCrawlerAPI.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Scrape competitor pricing pages weekly
- Crawl documentation and extract broken links
- Monitor product pages for content changes

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `WEBCRAWLERAPI_CREATE_CRAWL` | Create Crawl | Start a metered asynchronous crawl over a site and return its job ID. The crawl may visit and charge for up to items_limit pages; use GET_CRAWL_JOB to monitor it. |
| `WEBCRAWLERAPI_CREATE_FEED` | Create Feed | Create a recurring website-change feed. Creation immediately schedules an initial crawl that may consume metered credits, and future scheduled runs may also consume credits; delete the feed when it is no longer needed. |
| `WEBCRAWLERAPI_DELETE_FEED` | Delete Feed | Permanently cancel a feed so it cannot be resumed. The feed is removed from feed listings, but retained history may remain directly readable for 30 days. |
| `WEBCRAWLERAPI_GET_CRAWL_JOB` | Get Crawl Job | Get a crawl job's status, configuration, per-page results, content URLs, errors, and observed costs. Respect recommended_pull_delay_ms when polling. |
| `WEBCRAWLERAPI_GET_FEED` | Get Feed | Get one feed's configuration, lifecycle status, and recent run history, including per-run crawl counts and cost. Canceled feeds remain directly readable while retained by the provider. |
| `WEBCRAWLERAPI_GET_ORGANIZATION_COSTS` | Get Organization Costs | Return current spendable balance plus request count and USD usage for a date range. The connected API key is used for both organization routes. |
| `WEBCRAWLERAPI_LIST_FEED_CHANGES` | List Feed Changes | Return one page of detected feed changes as structured JSON, with an opaque continuation cursor for older pages. |
| `WEBCRAWLERAPI_LIST_FEEDS` | List Feeds | List active and paused feeds for the connected organization, newest first. Logically canceled feeds are omitted. |
| `WEBCRAWLERAPI_SCRAPE_PAGE` | Scrape Page | Scrape one web page synchronously and return requested content or structured extraction. This consumes metered credits; supplying a prompt adds $0.002 per request. |
| `WEBCRAWLERAPI_SET_FEED_STATE` | Set Feed State | Pause an active feed's future scheduled runs or resume a paused feed. Pausing does not stop a run that has already started, and resuming schedules future crawls that may consume metered credits. |

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute WebCrawlerAPI Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute WebCrawlerAPI actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Scrape https://webcrawlerapi.com and summarize the main product features'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'Scrape https://webcrawlerapi.com and summarize the main product features'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK for Python or TypeScript
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Initialize Client and Create Tool Router Session

Import and initialize the Composio client, then create a Tool Router session for WebCrawlerAPI
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to WebCrawlerAPI tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Crawl https://webcrawlerapi.com/docs and list the key API capabilities')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'Crawl https://webcrawlerapi.com/docs and list the key API capabilities'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
```
