## Endpoints

### get_sector_fares

Retrieve the lowest daily fare calendar for a given Air Premia route (origin-destination pair) over a date range. Returns per-day availability with fares broken down by cabin class (Economy and Premium Economy), including base fare, taxes, and total. Dates with no availability are marked as sold out. The API requires end_date to align to the last day of its month; any provided end_date is automatically snapped to the month's end. Supports a maximum date span of approximately two months from today.

**Estimated cost:** Metered
