## Tools (5)

- `find_offices`: Find lie detector (polygraph) test offices near a place. Search by city, state/region, or country (United States, Canada, or United Kingdom). Returns each matching office with its address, all-inclusive prices, and a booking link.
- `get_booking_status`: Check the status of an existing confirmed booking by its reference (e.g. LDT-2026072062783). Returns the booking status and location. A booking started via start_booking is not confirmed until the person completes payment on the website.
- `get_pricing`: Get polygraph examination pricing for a location. Returns the all-inclusive price tiers (single person, couple/two-person total, and group per-examinee) plus the non-refundable booking-fee deposit (fully refunded if we cannot accept your case or arrange your appointment) ($100 USD/CAD, or £225 in the UK).
- `get_service_info`: Get general information about the lie detector test service: what is offered, how booking works, the deposit and refund policy, the service area, and what happens after booking. Takes no arguments.
- `start_booking`: Start a lie detector test booking for a person. Records the enquiry and returns a reference plus a ready-to-complete booking link with the office pre-filled. IMPORTANT: the person must finish on the website themselves — choose a time, accept the terms, sign the agreement, pay the non-refundable deposit (fully refunded if we cannot book you), and complete a short pre-examination assessment. An agent cannot sign or pay on their behalf. Do not put the person's contact details in any URL.
