in‐browser splatnet 3

This is a guide for enabling the use of SplatNet 3 in your browser. Due to an update in August 2023, a userscript is now required to load the homepage.

Steps

1. Install a userscript manager, such as:

   • Tampermonkey (for Chrome, Firefox, Safari, Edge, and Opera)
   • Violentmonkey (for Chrome, Firefox, and Edge)
   • Greasemonkey (for Firefox only)

2. Run s3s (see the readme for usage) to generate an up-to-date config.txt. If you only want to access SplatNet and don't have a stat.ink API key, enter "skip" for this step during setup.

3. Open your config.txt and copy the value listed for gtoken (you can also use mitmproxy to obtain your token manually).

4. Go to https://gist.github.com/frozenpandaman/8cd8e66757d3478f3aa3839a38ddaa1e and click the "Raw" button. Click "Install" on the page that pops up to install the "s3s Use SplatNet 3 in-browser" userscript.

5. Navigate to https://api.lp1.av5ja.srv.nintendo.net/. When the alert box pops up, paste in your token. You'll have to do this every time you refresh the tab on the homepage of the web app. Since gtokens expire every few hours, you may need to re-run s3s, reload the page, and paste in a new value every so often, in the case that the homepage displays an error.

Changing the language

If you wish to use SplatNet 3 in a language other than English, go to https://api.lp1.av5ja.srv.nintendo.net/?lang=xx-XX where xx-XX is one of the available language codes.
