Problem with getting values from request using batch-CodePudding

I'm new in batch and i need to get a tag from a url like:
tag_name in url https://api.github.com/repos/pmmp/PocketMine-MP/releases/latest
So i found that someone was doing this to get it :

for /f "tokens=1,* delims=:" %%A in ('curl -ks https://api.github.com/repos/pmmp/PocketMine-MP/releases/latest ^| find "tag_name"') do (
    SET VERSION=%%B
    echo %VERSION%
)

But there is two problems :

This is getting with loop. isn't there any better way to get it?
It returns "4.2.4", Which its extra characters needs to be removed, (Clearly i need to have it like 4.2.4

Thx to you all.

Here's one option:

@For /F Tokens^=4^ Delims^=^" %%G In ('%SystemRoot%\System32\curl.exe -ks
 "https://api.github.com/repos/pmmp/PocketMine-MP/releases/latest" ^|
 %SystemRoot%\System32\findstr.exe /IR "\"tag_name\":" 2^>NUL') Do @Echo(%%G

You could of course use your own code and fix it by reading the usage information for the command you are using. You could do that by opening a Command Prompt window, typing for /? and pressing the ENTER key. Simply changing your delimiters to include the additional whitespace and comma characters, and modifying your variable expansion to use a tilde, should work for you.

It is generally a good idea to use tools that understand the language when processing a language. If you are on a supported windows system, powershell.exe is available, just as much as findstr.exe is available.

powershell.exe -NoLogo -NoProfile -Command ^
    "(& curl.exe -ks https://api.github.com/repos/pmmp/PocketMine-MP/releases/latest | ConvertFrom-Json).tag_name"

To put this into a batch-file, you could use:

FOR /F "delims=" %%A IN ('powershell.exe -NoLogo -NoProfile -Command ^
    "(& curl.exe -ks https://api.github.com/repos/pmmp/PocketMine-MP/releases/latest | ConvertFrom-Json).tag_name"') DO (SET "TAG_NAME=%%~A")
ECHO TAG_NAME is set to %TAG_NAME%
