I was not sure if there's any api for monorail, so, I made a small script to download/monitor issues from @ProjectZeroBugs issues ๐Ÿž. Should work for other projects as well.


#!/usr/bin/env python3

# Requirements: pip3 install pyppeteer requests halo

# Usage: ~/ -h
# ๐Ÿง ant4g0nist@ โžœ ~/ -h
# usage: Google Project Zero Issue Downloader [-h] [-f FINDER]
# optional arguments:
# -h, --help show this help message and exit
# -f FINDER, --finder FINDER
# name of the researcher.
# name of the researcher.
# ๐Ÿง ant4g0nist@ โžœ ~/ -f forshaw
