Facepunch API endpoints
I released this information at — 2026-04-17 19:12 in my discord server, I only saw 1 thread after my first release and it was on another forum. I have been pretty busy in real life so I have not really been that active on EPVP but I decided today to make a write-up about it.
It's no secret that Facepunch themselves are hiring in-house Anti Cheat programmers and even offer penetrator testers to help them through platforms like HackerOne
They have been doing this for a while now, however I decided to make a MITM proxy running on a raspberry PI model B intercepting HTTP/HTTPS traffic and dumping everything Facepunch is actively grabbing through their endpoints and there is some very interesting information in these endpoints
The endpoints are
api.facepunch.com
rust-api.facepunch.com
Endpoint 1 (/api/public/feedback/report/)
This get sent when you F7 report someone ingame on any server

The analytics packet is an interesting one cause it contain a lot of information from user-mode from your computer and even game information such as keybinds, active console commands
Hardware packet

EOS information
Code:

"eos_supported_system_config": "18",
"eos_tpm": "false",
"eos_secureboot": "true",
"eos_hvci": "false",
"eos_iommu": "false"
},
They also log stuff as, is_official, time_talking, graphics_settings, modified_convars
modified_convars is very interesting cause they could potentially tell that you are using an external/dma/internal cheat if you have example noclip enabled, godmode enabled, fov value changes
