ybaas (Yubibomb as a Service) is a Rust microservice that gives you a hosted yubibomb so your users don't have to deal with the complexities of installing and using the command line tool itself. You can use it to pretend to accidentally press your Yubikey while your IRC client has the keyboard focus! Usage example:

$ curl http://localhost:3030/hotp 869926
