# Enhanced Mode

> Use enhanced proxies for reliable scraping on complex sites

<Warning>
  The `proxy` parameter is deprecated. We recommend `auto` — the default — which lets Firecrawl handle proxy selection for you.
</Warning>

Firecrawl provides different proxy types to help you scrape websites with varying levels of complexity. Set the `proxy` parameter to control which proxy strategy is used for a request.

## Proxy types

| Type       | Description                                                                   |
| ---------- | ----------------------------------------------------------------------------- |
| `basic`    | Standard proxies suitable for most sites                                      |
| `enhanced` | Enhanced proxies for complex sites                                            |
| `auto`     | **Recommended.** Tries `basic` first, then retries with `enhanced` on failure |

If you do not specify a proxy, Firecrawl defaults to `auto`.

## Basic usage

Set the `proxy` parameter to choose a proxy strategy. The following example uses `auto`, which lets Firecrawl decide when to escalate to enhanced proxies.

<CodeGroup>
  ```python Python theme={null}
  from firecrawl import Firecrawl

  firecrawl = Firecrawl(
    # No API key needed to get started — add one for higher rate limits:
    # api_key='fc-YOUR-API-KEY',
  )

  # Choose proxy strategy: 'basic' | 'enhanced' | 'auto'
  doc = firecrawl.scrape('https://example.com', formats=['markdown'], proxy='auto')

  print(doc.warning or 'ok')
  ```

  ```js Node theme={null}
  import { Firecrawl } from 'firecrawl';

  const firecrawl = new Firecrawl({
    // No API key needed to get started — add one for higher rate limits:
    // apiKey: "fc-YOUR-API-KEY",
  });

  // Choose proxy strategy: 'basic' | 'enhanced' | 'auto'
  const doc = await firecrawl.scrape('https://example.com', {
    formats: ['markdown'],
    proxy: 'auto'
  });

  console.log(doc.warning || 'ok');
  ```

  ```bash cURL theme={null}

  // Choose proxy strategy: 'basic' | 'enhanced' | 'auto'
  # No API key needed to get started — add -H "Authorization: Bearer fc-YOUR-API-KEY" for higher rate limits:
  curl -X POST https://api.firecrawl.dev/v2/scrape \
      -H 'Content-Type: application/json' \
      -d '{
        "url": "https://example.com",
        "proxy": "auto"
      }'

  ```
</CodeGroup>

<Info>
  Enhanced proxy requests now cost the same as basic requests — **1 credit per request**. There is no longer any extra charge when `auto` escalates to an enhanced retry.
