Here are some examples on how to download files with get.php.

1. Get the "files" object of a given f_id. Take the MD5 hash value in the response.

fyicenter$ curl 'https://libgen.lc/json.php?object=f&ids=32216214' | python -m json.tool

{
  "32216214": {
    "editions": {
        "30969895": {
            "e_id": "32149882",

            "time_last_modified": "2021-07-17 14:40:07"
        }
    },
    "extension": "pdf",

2. Download a file by its MD5 hash value. The API address is moved.

fyicenter$ curl 'https://libgen.lc/get.php?md5=2da991ccc4cd63d23196a5c4a63a71ef'

<html>
<head><title>307 Temporary Redirect</title></head>
<body>
<center><h1>307 Temporary Redirect</h1></center>
<hr><center>nginx</center>
</body>
</html>

3. Show the new API address in the response header.

fyicenter$ curl -D header.txt 'https://libgen.lc/get.php?md5=2da991ccc4cd63d23196a5c4a63a71ef'

fyicenter$ more header.txt

Content-Length: 164
Connection: keep-alive
Location: https://cdn1.booksdl.org/get.php?md5=2da991ccc4cd63d23196a5c4a63a71ef

4. Download the file with the new API address. It returns no data and no error.

fyicenter$ curl 'https://cdn1.booksdl.org/get.php?md5=2da991ccc4cd63d23196a5c4a63a71ef' \
  > files-32216214.pdf 

fyicenter$ ls -l *.pdf 
-rw-r--r--  1 fyicenter  staff      0 Jun 18 21:33 files-32216214.pdf

5. Try the "-L" option to follow redirects. It returns the "Library Genesis" home page.

fyicenter$ curl -L 'https://libgen.lc/get.php?md5=2da991ccc4cd63d23196a5c4a63a71ef'

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ...
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title>Library Genesis</title>
...

6. Add the API key=Z380HIK7II2DL1W1. Now the file is downloaded.

fyicenter$ curl -L 'https://libgen.lc/get.php?md5=2da991ccc4cd63d23196a5c4a63a71ef&key=Z380HIK7II2DL1W1' \

fyicenter$ ls -l *.pdf 
-rw-r--r--@ 1 fyicenter  staff  216912 Jun 18 22:07 files-32216214.pdf
