@katestarbird The v1 API filter stream was cut off. It was in theory 'deprecated' a while ago when they posted a message at the top of the community forums site saying it was ending on the 8/3, but seems they took an extra week because of everything else breaking. It wasn't really deprecated because it wasn't mentioned anywhere else, and those forums were taken down for a few weeks, and even then not something many used them. Only option now is v2 version of this endpoint, but you will run into tweet limits much sooner unless you pay $$$ for the 'going to be removed a month ago' Premium subscription.
