YuriGarden Source

[FiorenMas]

@dragonx943 After writing a new extension YuriGarden for this source (https://github.com/keiyoushi/extensions-source), I found that it only accepts requests from Kotatsu. Is this a private API whitelisted exclusively for Kotatsu? If so, can I create an extension on Keiyoushi that mimics Kotatsu's requests?

@FiorenMas Kotatsu is not affiliated with YuriGarden or any other source. Whether a source works or not is entirely determined by how the parser and its client are implemented and used to make requests (headers, URLs, API patterns, rate limits, etc.), not by any special partnership with Kotatsu.

please read the code again (https://github.com/YakaTeam/kotatsu-parsers/blob/master/src%2Fmain%2Fkotlin%2Forg%2Fkoitharu%2Fkotatsu%2Fparsers%2Fsite%2Fvi%2FYuriGardenParser.kt).

The API is public, and you can clearly see how the data requests are handled there. Kotatsu / Yuki does not collaborate or work directly with any website. You are free to create whatever you like, as long as you do not violate the license.

@MuhamadSyabitHidayattulloh @InvalidDavid That's why I'm asking @dragonx943. Since he writes the code, he knows what I'm talking about. When using the Kotatsu user-agent Kotatsu/9.0 (Android 16;;; en), the API responds with a JSON file. However, when using another user-agent like Chrome or Firefox, it returns encrypted data. I need to decrypt the WASM on the website to get the private key to decrypt the API response. So, I think it's a private API. You can test it with this command:

set URL=https://api.yurigarden.com/api/chapters/5582
set COMMON_HEADERS=-H "Referer: https://yurigarden.com/" -H "Origin: https://yurigarden.com" -H "x-app-origin: https://yurigarden.com" -H "Accept: application/json"

echo ============================================================
echo  YuriGarden API - User-Agent Response Test
echo  URL: %URL%
echo ============================================================

echo.
echo [1] Kotatsu UA (should return plain JSON):
echo ----------------------------------------
curl -s %COMMON_HEADERS% -H "User-Agent: Kotatsu/9.0 (Android 16;;; en)" %URL%

echo.
echo.
echo [2] Chrome Desktop UA (should return encrypted):
echo ----------------------------------------
curl -s %COMMON_HEADERS% -H "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/145.0.0.0 Safari/537.36" %URL%

echo.
echo.
echo [3] Firefox Android UA (should return encrypted):
echo ----------------------------------------
curl -s %COMMON_HEADERS% -H "User-Agent: Mozilla/5.0 (Android 13; Mobile; rv:121.0) Gecko/144.0 Firefox/144.0" %URL%

Kotatsu's UA has long been whitelisted on Yuri Garden source (since July 9, 2025) by the website owner. Kotatsu may / may not be affiliated with some sources, so what you see is to be expected.

You can use it for Keiyoushi repo, however I cannot guarantee that you can use it long-term as the website owner may remove it at any time.
