Implement demand-based dynamic pricing for parking operators using AirGarage's per-spot dynamic pricing fields

Steps

1. Pull a spot's current pricing snapshot via GET https://api.airgarage.com/spots/{uuid}, which returns both posted rates (price_hourly/price_daily/price_monthly) and separate dynamic_price/dynamic_max fields
2. Treat price_hourly as the base/rack rate and dynamic_price as the current demand-adjusted effective rate, with dynamic_max as the ceiling
3. Re-fetch spot detail on a schedule, or immediately before starting a rental, so a booking always uses the latest dynamic rate rather than a stale cached price
4. When starting a rental via POST /rentals, confirm in testing which rate (posted vs. dynamic) is actually charged, since the public docs don't show a rental-creation parameter for explicitly selecting between them
5. Build your own alerting if dynamic_price approaches dynamic_max, since the public API doesn't expose a 'pricing rule' endpoint for configuring the dynamic-pricing algorithm itself, only its output
