A Flask API that scrapes large buy and sell orders of Ethereum ERC20 tokens could be a useful tool for cryptocurrency traders and investors. The API would use web scraping techniques to gather data on the largest buy and sell orders for a specific ERC20 token on a decentralized exchange. This information could then be accessed by users through the API's endpoint, allowing them to make informed trading decisions based on real-time market data. Additionally, the API could be set up to automatically scrape the data at regular intervals, providing users with up-to-date information on market trends and fluctuations. Overall, this type of Flask API could be a valuable resource for anyone interested in trading Ethereum ERC20 tokens.
