No longer possible

The emmVRC API always returns "invalid combination", regardless of whether or not an account exists.

.bunny. did not contribute to this project in any way. Abyss client ($100) sells a public GitHub feature.

This project will probably break in the future

Simple project written in Rust to detect if a user has ever used emmVRC.

This project works by sending a request to the emmVRC servers. Based on the status code we can determine if the user has a password (pin) set.

The username field seems to be ignored except for when it is empty, and "loginKey" is effectively ignored due to this being a single sign on attempt.

For getting user input: text_io

For sending HTTP requests: reqwest

For using async: tokio
