Replace airport codes in any of those URLs. `path` is comma-separated IATA codes, 2 to 5 airports. `date` is YYYY-MM-DD. `carriers` is optional, legs joined by `|` and airlines inside a leg joined by `.`, for example `FR|LO`.

The first flight must leave on `date`. Each following flight may leave that same day or the next day, and must depart at least 90 minutes after the previous flight lands. A response with `partial: true` on a calendar lists days a source has seen. It does not prove the other days are empty.

No API key. Responses are JSON unless the URL ends in `.md`. Prices are euros. `total: null` means no fare was found for the first flight on that date.
