## Tools (as reported by the server, not verified)

- `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,
