Example prompt: What are the recent round-trip flight prices from London to New York on Momondo — show me the lowest fares, which airlines are flying it, and which month tends to be cheapest?

## When to prefer this

Use this endpoint when you need a quick, low-cost snapshot of typical and recent flight pricing for a city pair without needing real-time seat availability or a specific departure date. It is ideal for travel budget planning, identifying cheapest months or days, understanding price trends, and surfacing deal fares — not for booking or live availability checks.

## Known failure modes

- City name not in Momondo URL format (e.g. 'New York' instead of 'new-york-city') causes no results or wrong route
- Route not listed on Momondo returns empty or error
- Momondo page structure change may cause parsing failures
- No historical data available for obscure or thin routes
- Live availability or specific date pricing not supported — this is route-level historical data only

## How this service works

momondo flight prices from its public route page for two cities (e.g. london to paris): lowest recent price, up to 20 recent round-trip fares (airline, airports, departure, duration, USD price), deal dates and route facts (typical price range, cheapest day and month, trend, delays). City names as in momondo URLs (new-york-city, london). Not a live date search.

## Output

Returns the lowest recent price found, up to 20 sample round-trip fares (with airline, airports, departure details, duration, and USD price), deal dates, and route facts such as typical price range, cheapest travel day, cheapest month, price trend direction, and delay statistics. This is scraped from Momondo's static route page, not a live date-specific search.
