How It Works

The MX3 Fitness platform uses a legacy PHP/HTML system (AccelSite) without a JSON API. This server:

1. Authenticates via cookie-based login with userName, password, and hidden form fields
2. Fetches schedule HTML via POST /reserve-noe-station with locID=51550&refreshDate={date}
3. Parses slot availability from <p id="res_time_{stationId}_{date}_{time}"> elements using cheerio
4. Books slots via v2=true&reserve={stationId}&res_date={date}&res_time={time}
5. Cancels via v2=true&unreserve={reservationId}&resourceID={stationId}
6. Reads reservations from the full page HTML under #my_reservations

Session cookies are managed in-memory with automatic re-authentication on expiry.
