## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Search Seats.aero's cached award availability for business class flights from SFO or LAX to LHR or FRA between January 15 and January 22, 2026, filtering to United and Lufthansa only, sorted by lowest mileage — show me up to 50 results and include trip details.

## When to prefer this

Use this endpoint when you need to search for airline award/miles redemption availability across multiple carriers and routes using Seats.aero's aggregated cached data. Prefer this over live flight search APIs when the goal is finding mileage redemption opportunities rather than paid fares, especially when filtering by cabin class or specific alliance carriers.

## Known failure modes

- Missing required origin_airport or destination_airport returns validation error
- Invalid date format (not YYYY-MM-DD) causes rejection
- take value outside 10–1000 range returns error
- Invalid cabin enum value returns error
- No award availability found for the specified route/dates returns empty result set
- Stale cache may not reflect real-time award space

## How this service works

## Output

Returns a paginated list of cached award availability records from Seats.aero including flight segments, cabin class, mileage costs, carrier information, and optionally trip-level details, along with a cursor for fetching the next page of results.
