Tool: search

Searches live flight offers between an origin and destination for given travel dates. Supports one-way and round-trip searches with flexible passenger counts and cabin class. Returns price-ranked results grouped by number of stops, showing the cheapest options from multiple airlines and booking platforms. The tool queries external flight aggregator APIs in real time and includes affiliate booking links. It does not book flights, modify reservations, charge users, or store user data.

Parameters

Response Format

Results are grouped by number of stops with the cheapest options per group:

Result Validity

Search results and booking links are valid for approximately 15 minutes. Flight prices are determined through a real-time bidding process and are not guaranteed beyond this window. If a user wants to book, they should do so promptly. For stale results, run a new search.

Error Responses

The server returns structured errors with suggestions:

• airport_not_found -- airport could not be resolved. Try an IATA code, city name, or airport name.
• disambiguation_needed -- multiple airports found (e.g. "New York" returns JFK, LGA). Pick one and retry.
• invalid_date -- date format not recognized. Use YYYY-MM-DD, DD.MM.YYYY, or similar.
• no_results -- no flights available for the given criteria. Try different dates or a nearby airport.
