# Get Flight Price History

`GET /ad-deals/flights/{route_slug}/price-history`

Public read-only price-history for a flight route (SEO route pages).

Mirrors the ad-deal endpoint's route resolution + rate limit, but returns a
normalized SerpAPI price-history series instead of live bookable fares. The
content path writes no DB rows and is cached for 24h.

## Path parameters

- `route_slug` string, required

## Query parameters

- `departure_date` string, date, nullable — Representative departure date (YYYY-MM-DD).
- `return_date` string, date, nullable — Representative return date (YYYY-MM-DD).
- `utm_origin` string, nullable
- `utm_destination` string, nullable
- `timezone` string, nullable
