# Welcome to Farelint

> Airline data infrastructure for the products you're building.

Farelint is being built to turn airline searches into structured data: request a fresh collection, monitor a market, or work with retained fare observations through one consistent interface.

> [!NOTE]
>
> Pre-release documentation. The API contract and launch plans below are proposed; production endpoints, API keys and billing are not available yet. [Request pilot access](https://out-of-cyprus-larnaca.m3k3r1.chatgpt.site/#access).

## Three ways to use the data

**On demand.** Submit a specific route and travel dates to initiate collection.

**Scheduled.** Define a route set, departure window and refresh cadence to build a recurring feed.

**Historical.** Query observations actually retained for your sources. Preserve gaps, original currencies and matching search criteria.

## Every price comes with context

The data contract separates search identity, source, price basis, observation time and collection status. Unknown baggage, tax or fare conditions remain explicit. A fare observation is not a reservation or checkout-confirmed availability.

The intended service is data delivery for travel platforms, pricing teams and AI products. Coverage, permitted data use and service targets are confirmed per pilot.
