      "description": "Get a courier price quote, book a REAL point-to-point courier/parcel delivery in Calgary, check a booking's status, or cancel one - no BuyNearby account needed. action:'book' immediately creates the booking and auto-assigns a driver if one is available, exactly like a human finishing the form at buynearby.store/courier-book.php; the response's booking_ref is a real, live booking, not a draft. Payment is a link texted to the customer afterward (this call never charges a card). Use action:'quote' first if you just need a price before the user has decided to book. Use action:'status' to check on an existing booking, and action:'cancel' to self-cancel one (only while it's still 'pending' or 'assigned' — once a driver has picked up the package, direct the customer to support instead).",
