Connect websites to automatically crawl and sync web pages into your Supermemory knowledge base. The web crawler respects robots.txt rules, includes SSRF protection, and automatically recrawls sites on a schedule.

<Warning>
The web crawler connector requires a **Scale Plan** or **Enterprise Plan**.

## Quick Setup

### 1. Create Web Crawler Connection

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    import Supermemory from 'supermemory';

    const client = new Supermemory({
      apiKey: process.env.SUPERMEMORY_API_KEY!
    });

    const connection = await client.connections.create('web-crawler', {
      redirectUrl: 'https://yourapp.com/callback',
      containerTag: 'user-123',
      documentLimit: 5000,
      metadata: {
        startUrl: 'https://docs.example.com'
      }
    });

    // Web crawler doesn't require OAuth - connection is ready immediately
    console.log('Connection ID:', connection.id);
    console.log('Connection created:', connection.createdAt);
    // Note: connection.authLink is undefined for web-crawler
    ```
  </Tab>
  <Tab title="Python">
    ```python
    from supermemory import Supermemory
    import os

    client = Supermemory(api_key=os.environ.get("SUPERMEMORY_API_KEY"))

    connection = client.connections.create(
        'web-crawler',
        redirect_url='https://yourapp.com/callback',
        container_tag='user-123',
        document_limit=5000,
        metadata={
            'startUrl': 'https://docs.example.com'
        }
    )

    # Web crawler doesn't require OAuth - connection is ready immediately
    print(f'Connection ID: {connection.id}')
    print(f'Connection created: {connection.created_at}')
    # Note: connection.auth_link is None for web-crawler
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/v3/connections/web-crawler" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{
        "redirectUrl": "https://yourapp.com/callback",
        "containerTag": "user-123",
        "documentLimit": 5000,
        "metadata": {
          "startUrl": "https://docs.example.com"
        }
      }'

    # Response: {
    #   "id": "conn_wc123",
    #   "redirectsTo": "https://yourapp.com/callback",
    #   "authLink": null,
    #   "expiresIn": null
    # }
    ```
  </Tab>
</Tabs>

### 2. Connection Established

Unlike other connectors, the web crawler doesn't require OAuth authentication. The connection is established immediately upon creation, and crawling begins automatically.

### 3. Monitor Sync Progress

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    // Check connection details
    const connection = await client.connections.getByTags('web-crawler', {
      containerTags: ['user-123']
    });

    console.log('Start URL:', connection.metadata?.startUrl);
    console.log('Connection created:', connection.createdAt);

    // List synced web pages
    const documents = await client.connections.listDocuments('web-crawler', {
      containerTags: ['user-123']
    });

    console.log(`Synced ${documents.length} web pages`);
    ```
  </Tab>
  <Tab title="Python">
    ```python
    # Check connection details
    connection = client.connections.get_by_tags(
        'web-crawler',
        container_tags=['user-123']
    )

    print(f'Start URL: {connection.metadata.get("startUrl")}')
    print(f'Connection created: {connection.created_at}')

    # List synced web pages
    documents = client.connections.list_documents(
        'web-crawler',
        container_tags=['user-123']
    )

    print(f'Synced {len(documents)} web pages')
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    # Get connection details by provider and tags
    curl -X POST "https://api.supermemory.ai/v3/connections/web-crawler/connection" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"containerTags": ["user-123"]}'

    # Response includes connection details:
    # {
    #   "id": "conn_wc123",
    #   "provider": "web-crawler",
    #   "createdAt": "2024-01-15T10:00:00Z",
    #   "documentLimit": 5000,
    #   "metadata": {"startUrl": "https://docs.example.com", ...}
    # }

    # List synced documents
    curl -X POST "https://api.supermemory.ai/v3/connections/web-crawler/documents" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"containerTags": ["user-123"]}'

    # Response: Array of document objects
    # [
    #   {"title": "Home Page", "type": "webpage", "status": "done", "url": "https://docs.example.com"},
    #   {"title": "Getting Started", "type": "webpage", "status": "done", "url": "https://docs.example.com/getting-started"}
    # ]
    ```
  </Tab>
</Tabs>

## Supported Content Types

### Web Pages
- **HTML content** extracted and converted to markdown
- **Same-domain crawling** only (respects hostname boundaries)
- **Robots.txt compliance** - respects disallow rules
- **Content filtering** - only HTML pages (skips non-HTML content)

### URL Requirements

The web crawler only processes valid public URLs:
- Must be a public URL (not localhost, private IPs, or internal domains)
- Must be accessible from the internet
- Must return HTML content (non-HTML files are skipped)

## Sync Mechanism

The web crawler uses **scheduled recrawling** rather than real-time webhooks:

- **Initial Crawl**: Begins immediately after connection creation
- **Scheduled Recrawling**: Automatically recrawls sites that haven't been synced in 7+ days
- **No Real-time Updates**: Unlike other connectors, web crawler doesn't support webhook-based real-time sync

<Note>
The recrawl schedule is automatically assigned when the connection is created. Sites are recrawled periodically to keep content up to date, but updates are not instantaneous.
</Note>

## Connection Management

### List All Connections

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    // List all web crawler connections
    const connections = await client.connections.list({
      containerTags: ['user-123']
    });

    const webCrawlerConnections = connections.filter(
      conn => conn.provider === 'web-crawler'
    );

    webCrawlerConnections.forEach(conn => {
      console.log(`Start URL: ${conn.metadata?.startUrl}`);
      console.log(`Connection ID: ${conn.id}`);
      console.log(`Created: ${conn.createdAt}`);
    });
    ```
  </Tab>
  <Tab title="Python">
    ```python
    # List all web crawler connections
    connections = client.connections.list(container_tags=['user-123'])

    web_crawler_connections = [
        conn for conn in connections if conn.provider == 'web-crawler'
    ]

    for conn in web_crawler_connections:
        print(f'Start URL: {conn.metadata.get("startUrl")}')
        print(f'Connection ID: {conn.id}')
        print(f'Created: {conn.created_at}')
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    # List all connections
    curl -X POST "https://api.supermemory.ai/v3/connections/list" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"containerTags": ["user-123"]}'

    # Response: [
    #   {
    #     "id": "conn_wc123",
    #     "provider": "web-crawler",
    #     "createdAt": "2024-01-15T10:30:00.000Z",
    #     "documentLimit": 5000,
    #     "metadata": {"startUrl": "https://docs.example.com", ...}
    #   }
    # ]
    ```
  </Tab>
</Tabs>

### Delete Connection

Remove a web crawler connection when no longer needed:

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    // Delete by connection ID
    const result = await client.connections.delete('connection_id_123');
    console.log('Deleted connection:', result.id);

    // Delete by provider and container tags
    const providerResult = await client.connections.deleteByProvider('web-crawler', {
      containerTags: ['user-123']
    });
    console.log('Deleted web crawler connection for user');
    ```
  </Tab>
  <Tab title="Python">
    ```python
    # Delete by connection ID
    result = client.connections.delete('connection_id_123')
    print(f'Deleted connection: {result.id}')

    # Delete by provider and container tags
    provider_result = client.connections.delete_by_provider(
        'web-crawler',
        container_tags=['user-123']
    )
    print('Deleted web crawler connection for user')
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    # Delete by connection ID
    curl -X DELETE "https://api.supermemory.ai/v3/connections/connection_id_123" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY"

    # Delete by provider and container tags
    curl -X DELETE "https://api.supermemory.ai/v3/connections/web-crawler" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"containerTags": ["user-123"]}'
    ```
  </Tab>
</Tabs>

<Note>
Deleting a connection will:
- Stop all future crawls from the website
- Keep existing synced documents in Supermemory (they won't be deleted)
- Remove the connection configuration
</Note>

## Advanced Configuration

### Content Filtering

Control which web pages get synced using the settings API:

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    // Configure intelligent filtering for web content
    await client.settings.update({
      shouldLLMFilter: true,
      includeItems: {
        urlPatterns: ['*docs*', '*documentation*', '*guide*'],
        titlePatterns: ['*Getting Started*', '*API Reference*', '*Tutorial*']
      },
      excludeItems: {
        urlPatterns: ['*admin*', '*private*', '*test*'],
        titlePatterns: ['*Draft*', '*Archive*', '*Old*']
      },
      filterPrompt: "Sync documentation pages, guides, and API references. Skip admin pages, private content, drafts, and archived pages."
    });
    ```
  </Tab>
  <Tab title="Python">
    ```python
    # Configure intelligent filtering for web content
    client.settings.update(
        should_llm_filter=True,
        include_items={
            'urlPatterns': ['*docs*', '*documentation*', '*guide*'],

        },
        filter_prompt="Sync documentation pages, guides, and API references. Skip admin pages, private content, drafts, and archived pages."
    )
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    # Configure intelligent filtering for web content
    curl -X PATCH "https://api.supermemory.ai/v3/settings" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \

## Security & Compliance

### SSRF Protection

Built-in protection against Server-Side Request Forgery (SSRF) attacks:
- Blocks private IP addresses (10.x.x.x, 192.168.x.x, 172.16-31.x.x)
- Blocks localhost and internal domains
- Blocks cloud metadata endpoints
- Only allows public, internet-accessible URLs

### URL Validation

All URLs are validated before crawling:
- Must be valid HTTP/HTTPS URLs
- Must be publicly accessible
- Must return HTML content
- Response size limited to 10MB


<Warning>
**Important Limitations:**
- Requires Scale Plan or Enterprise Plan
- Only crawls same-domain URLs
- Scheduled recrawling means updates are not real-time
- Large websites may take significant time to crawl initially
- Robots.txt restrictions may prevent crawling some pages
- URLs must be publicly accessible (no authentication required)
</Warning>
