Thanks @Wendong-Fan .
If a class depends on multiple tokens at the same time, it seems that only one api_key can be verified.

Hey @Wendong-Fan , left some comments below

A situation that currently does not meet expectations:

class ExampleClass:
    def __init__(self, messages: List[str], key_1: str = None, api_key_2: str = None):
        self._key1 = key_1 or os.environ.get("API_KEY_1")
        self._key2 = api_key_2 or os.environ.get("API_KEY_2")
        self.messages = messages

    @api_keys_required(
        [
            ("key_1", 'API_KEY_1'),
            ("api_key_2", 'API_KEY_2'),
        ]
    )
    def run(self):
        print("API keys validated!")


if __name__ == "__main__":
    # Example with API_KEY_1 provided in arguments
    obj = ExampleClass(messages=["xx"], key_1="API", api_key_2="dfadf")
    obj.run()
    
"""

    raise ValueError(
