This is a CLI primarily designed for your Claw to search for available tennis courts and book them without slow browser automation (if you're in San Francisco or another area powered by rec.us).

Perhaps the most interesting part is the API documentation that was entirely written by Claude Code by reverse engineering the frontend and trying stuff, with minimal steering:

To be honest, now that the docs are done, I'm not sure the CLI even adds value, as the Claw (if given the API docs) can curl its way around pretty efficiently and handles unforeseen situations much better.
