Common Use Cases

1. Find the cheapest flight to a destination

Search without a specific date to get the cheapest options for the whole month:

curl "https://moltflights.com/api/search?origin=LHR&destination=TYO"

2. Compare prices across dates

Run multiple searches for different dates and compare:

for date in 2026-04-01 2026-04-08 2026-04-15; do
  echo "=== $date ==="
  curl -s "https://moltflights.com/api/search?origin=HEL&destination=BKK&date=$date" | head -20
done

3. Price monitoring / alerts (cron job)

Check a route daily and alert when price drops below a threshold:

# Run daily via cron: 0 8 * * * /path/to/check-price.sh
PRICE=$(curl -s "https://moltflights.com/api/search?origin=HEL&destination=BKK&date=2026-05-01" 
  | grep -o '"price":"€[0-9]*"' | head -1 | grep -o '[0-9]*')

if [ "$PRICE" -lt 400 ]; then
  echo "Deal found: HEL→BKK for €$PRICE"
fi

4. Multi-city search

Search several routes and pick the cheapest:

for dest in BKK TYO BCN LIS; do
  echo "=== HEL → $dest ==="
  curl -s "https://moltflights.com/api/search?origin=HEL&destination=$dest" 
    | grep -o '"price":"€[0-9]*"' | head -1
done
