The 'ERC20 Daily Token Transfer' API endpoint provides a count of ERC20 token transfer transactions on a specified network for a given date range. Users are requested to provide two parameters: 'dates', which is a range of dates to measure the transactions (format: 'YYYY-MM-DD' to 'YYYY-MM-DD'), and 'network', a text input inquiring the specific blockchain network to get the details from. The output of the endpoint is a table consisting of two columns: 'date' showing each day in the specified range and 'erc20_txs' showing the count of ERC20 token transfers occurred on that day. For a clear visual interpretation, data can be represented using a line chart which presents the count of ERC20 token transfers against each day in the provided date range. This can help users to easily track and analyze daily transfer activity.
