The IA Client – The Swiss Army Knife of Internet Archive
Started in 2012 and overseen primarily by Archive employee Jake Johnson, the internetarchive client (which is generally just called “ia”) is both a set of libraries and a command-line program for doing a wide range of activities and actions with the archive without having to come in through the website. There’s a range of advantages and differences from using the web interface, mostly that it can be called as a command-line request, and return the results (success, failure, other information) right into your scripts. It is coded to be in lock-step with our APIs and system, and does its best to respect capacity as well as return informative messages about success or errors.
