stamper

#!/usr/bin/env python
#
# A script to create timestamps using: http://www.originstamp.org
# The script has two commands:
# "stamp" stamps
#
#    stamper stamp FILENAME [FILENAME [FILENAME...]]
#
# and "check" checks:
#
#    stamper check  FILENAME [FILENAME [FILENAME...]]
#
### Install:
#
# The script is written in python 3, and requires the `sh`, `path.py`,
# `requests` and `arrow` modules to be installed.
#
# Also, you will need to request an API key from the following page:
#     http://www.originstamp.org/developer
#
# and save the key to ~/.originstamp.key

Thank you for this.
But note that this uses the old API which doesn't work any more.
OriginStamp now provides SWIG-generated client code in many languages for download (via a popup - look closely) at https://app.originstamp.org/plugins
