day 1： I tried to obtain historical data from GMGN and Dexscreener, but it was not ideal. Finally, I obtained it through the defi_ictivities data from Solscan, which includes important data for Token Swap and Add/Remove Liquidity. Prompt core: Inform the frontend of the API and data structure for obtaining data. Due to API limitations, time needs to be divided. Code logic: Enter the CA and CA creation date, divide the time from the current time to the creation date into 1-hour intervals, obtain data in blocks, and save them to the database
