Need a simple scrapper

I wrote the scrapper to fetch the collection info from OpenSea.io for personal purpose. And it's running as expected. But minor issue is that the spider has some request limit. If you are experienced scrapping guy, you can fix it shortly. I tried with free proxies online, and it worked. but unexpected result because OpenSea has max limit 1000 requests per day.
Looking for an experienced guy to fix it shortly. If you have similar experiences you will fix it in less than 1 hour.
