## Rules

- GET only. No API key. CORS allows any origin on /api/.
- Cache /api/price and /api/leg. They call airlines. Prefer /api/v1/routes for "how can I fly".
- total: null means no fare for the first flight that day. It does not mean the route is free.
- City names in the data are the airport's published name, usually English.
