How to get "files" objects with Library Genesis API, json.php, for a given modification date range?

If you want to get all file objects that were modified with a given date range, you can call the Library Genesis API, json.php, with object=f, mode=modified, timefirst={date} and timelast={date} parameters.

For example, the following call returns all "files" objects that were modified from 2021-09-02 to 2021-09-04.

fyicenter$ curl 'https://libgen.lc/json.php?object=f&mode=modified&timefirst=2021-09-02&timelast=2021-09-04' | python -m json.tool

        "time_last_modified": "2021-09-02 15:03:21",
        ...
    ...

The result shows that the file object (id=94068096) was added on 2021-07-17 and modified later on 2021-09-02.

You can also retrieve files that were added with a given date range using the mode=last parameter. For example, the following call returns all "files" objects that were added from 2021-09-02 to 2021-09-04.

fyicenter$ curl 'https://libgen.lc/json.php?object=f&mode=last&timefirst=2021-09-02&timelast=2021-09-04' | python -m json.tool | grep md5 | wc

      15      30     765

There were more than 15 files added during that 2-day period.
