Available Tools
5 toolsbuild_booking_linkARead-onlyIdempotent
Generate only an external booking link for an already chosen route. Use after route details are known or after compare_routes/search_travel_options; do not use as the first step when the user still needs search guidance. Read-only, no authentication, no booking completion, and no reservation side effects. The returned link may be commission-eligible and is disclosed in output.
Inputs: origin, destination, departure_date, return_date, +1 more.
compare_routesARead-onlyIdempotent
Compare two or more airport route pairs side by side. Use when the user is choosing between alternate origins, destinations, or airports; use search_travel_options for one dated route and get_airport_info for a single airport lookup. Read-only, no authentication, no booking side effects. Responses may include commission-eligible external booking links for each route.
Inputs: routes (required).
explain_travel_timingARead-onlyIdempotent
Explain general travel timing and logistics, including booking windows, airport arrival timing, layovers, and seasonal considerations. Use for advice questions like when to book or how early to arrive; use search_travel_options when the user wants route-specific flight search. Read-only, no authentication, no external booking link, and no booking side effects.
Inputs: origin, destination.
get_airport_infoARead-onlyIdempotent
Look up metadata for one airport by IATA code. Use to validate or explain a single airport code before route planning; use search_travel_options for an actual trip search and compare_routes for multiple origin-destination pairs. Read-only, no authentication, no external booking links, and no booking side effects.
Inputs: code (required).
search_travel_optionsARead-onlyIdempotent
Primary travel search workflow for one origin-destination airport pair. Use when the user wants flight/trip options for a specific route; use compare_routes for multiple routes, build_booking_link only when route details are already known, and get_airport_info only to validate one airport. Read-only, no authentication, no booking side effects. return_date is optional; omit it for one-way trips. Responses include route metadata and may include commission-eligible external booking links.
Inputs: origin (required), destination (required), departure_date, return_date, +1 more.
