Ошибка 429 при парсинге с сайта

Всем здравствуйте. Недавно написал программу, которая ищет контерпики для доты. Написал вручную словари, в которых описаны преимущества одного героя над другим. Но дело в том, что при каждом патче эти данные будут меняться, а их переписывать очень долго, поэтому хотел написать парсинг, чтобы не мучиться. Но тут появилась другая проблема, связанная с ошибкой 429 (Too many requests). Как я понял это сработала защита от DDOS-атак. Вот мой код:
