Therefore, I calculated the amount of data needed for a 30-day verification using bitFlyer's API to retrieve execution data. I published this downloader library as a Rust crate, with features including repeatedly hitting the API to write to MySQL or standard output, resuming from interruptions, and easy customization by simply implementing and passing traits.
