get_capabilities | What Airfare Brain covers: airlines, how fees are researched and dated, what it does NOT do (no live fares, no booking), and the sister tool for car hire. |
list_airlines | List every airline with a fee table: name, IATA code, the date its fees were checked, and its page. |
airline_fees | One airline's published extra fees (bags, seats, priority, check-in, changes, payment), each with the price range, when bought (at booking / later / airport), how it is charged, its source URL and the date checked. Optionally filter by category. |
true_cost | The true cost of a flight on one airline. Pass `fare` (the total for the whole party, from a flight-search tool or the person) to get fare + extras; without it you get the extras alone. Extras = what the person chooses (cabin bag, checked bag by kg, seat, priority, infants) for their party and trip, |
