A free flight-price API that tells you buy or wait, not just today's fare

Every flight comparison site shows you today's cheapest fare. None of them will tell you to wait — it costs them the booking commission.

Piratefly watches flight prices over time and answers the actual question: is this price good, or should you wait? We just opened that logic up as a free JSON API.

The endpoint

GET https://next.piratefly.com/v1/analisi?origine=FCO&destinazione=BCN

Give it an IATA origin and destination, get back today's cheapest fare, where it sits against that route's own price history (percentile), and a buy/wait verdict.

curl "https://next.piratefly.com/v1/analisi?origine=FCO&destinazione=BCN"

We only publish a verdict once a route has at least 8 price observations behind it — below that we say nothing rather than guess. Feedback and route requests welcome.
