- The nested access pattern
data['data']could benefit from safer navigation to avoid KeyError exceptions. Consider usingdata.get('data')instead of direct dictionary access.

The comment references a 'problematic IP' but doesn't explain why it's problematic. Consider adding context about why this specific IP range needs to be filtered.

There appears to be a corrupted or missing emoji/unicode character (�) in the log message. This should be replaced with a proper emoji or removed.

The magic number 1024 should be defined as a named constant (e.g., RESPONSE_READ_SIZE = 1024) to improve code maintainability and make the purpose clearer.

The Python version requirement was upgraded from 3.7 to 3.9, which is a potentially breaking change for users on older Python versions. Consider documenting this breaking change more prominently or providing a migration guide.
