Farelint: Airline fare data API and MCP for builders

Hi Product Hunt — I'm Miguel, the maker of Farelint.

Living in Cyprus, I kept struggling to find flights off the island and felt I was paying more than I should. That started as a consumer problem, but led me toward the data behind travel products.

Farelint is an airline-data API for travel software, analytics teams and AI agents. Specify an airline, route, dates and passengers, then inspect structured fare observations through HTTP or MCP.

The useful part is the context around the price:

• When it was captured and which trip was requested

• Original currency and whether the price is per adult, a party total or a supplement

• Complete, partial and failed collection outcomes

• Missing fields that stay explicit rather than being guessed

The gallery includes a saved pilot capture from 30 October 2026 and the MCP setup docs; the sample fare is not a current quote.

This launch is an early developer pilot. The docs and example JSON are public. We confirm the airline, route and request shape before activating live collection. We have tested limited workflows for Ryanair, easyJet, AEGEAN, Emirates and Qatar Airways; that does not mean every route or passenger combination is supported.

Farelint supplies observations, not ticketing or checkout-guaranteed fares. The first goal is a small integration that a team can evaluate against its real requirements.

If you build a travel app or AI agent, or work with airfare data, what is missing from your current sources? Which airline, route, fields and freshness requirement would make a pilot useful?

I'd love your feedback, especially on the data contract and the first sources worth expanding.
