 For simple HTTP requests, there's a `Fetcher` class that can be imported and used as below:
 ```python
 from scrapling.fetchers import Fetcher
-page = Fetcher.get('https://httpbin.org/get', impersonate="chrome")
+page = Fetcher.get('https://scrapling.requestcatcher.com/get', impersonate="chrome")
 ```
 With that out of the way, here's how to do all HTTP methods:
 ```python
 >>> from scrapling.fetchers import Fetcher
->>> page = Fetcher.get('https://httpbin.org/get', stealthy_headers=True, follow_redirects=True)
->>> page = Fetcher.post('https://httpbin.org/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030')
->>> page = Fetcher.put('https://httpbin.org/put', data={'key': 'value'})
->>> page = Fetcher.delete('https://httpbin.org/delete')
+>>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)
+>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030')
+>>> page = Fetcher.put('https://scrapling.requestcatcher.com/put', data={'key': 'value'})
+>>> page = Fetcher.delete('https://scrapling.requestcatcher.com/delete')
 ```
 For Async requests, you will replace the import like below:
 ```python
 >>> from scrapling.fetchers import AsyncFetcher
->>> page = await AsyncFetcher.get('https://httpbin.org/get', stealthy_headers=True, follow_redirects=True)
->>> page = await AsyncFetcher.post('https://httpbin.org/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030')
->>> page = await AsyncFetcher.put('https://httpbin.org/put', data={'key': 'value'})
->>> page = await AsyncFetcher.delete('https://httpbin.org/delete')
+>>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)
+>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030')
+>>> page = await AsyncFetcher.put('https://scrapling.requestcatcher.com/put', data={'key': 'value'})
+>>> page = await AsyncFetcher.delete('https://scrapling.requestcatcher.com/delete')
 ```
