Show HN: Python CLI for the Have I Been Pwned API (MVP)

Hi fellow HNers - OP here,

I thought it was about time I submitted something other than a story or a question :)

This project was born with Troy Hunt's Lenovo competition for Have I Been Pwned, but I think it's useful enough to show here.

It provides a (fairly minimal, at this stage) commandline Python script to check a list of e-mail addresses against HIBP, and report back any hits. It will keep tabs of what has been reported, and subsequently only report new items. It can also optionally e-mail affected accounts (useful if you want to monitor other people's addresses, or if you have multiple addresses that you don't want to sign up to HIBP).

The script can be run directly, or via a cron job. The outputs can be parsed to provide feedback on the commandline (or elsewhere) - see some examples in the README.

For a list of planned updates, please see the README.

This is my first Show HN, so go easy, but I'd be very happy to hear thoughts and suggestions!
