# LetsFG/LetsFG

Agent-native flight & hotel search and booking — MCP server, CLI, and Python/JS SDKs. Hundreds of airlines plus the major booking sites, with per-flight reliability history. Free-cancellation hotel rates: hold the room with a small upfront charge, then pay the balance later by link, up to the hotel's own deadline.

## What it is
LetsFG is an agent-native flight and hotel search and booking platform exposing its engine via a REST API, an MCP server, a CLI, and Python/TypeScript SDKs. It covers hundreds of airlines and major booking sites, with per-flight reliability history and free-cancellation hotel rates that can be held with a small upfront charge.

## Use cases
- search flights from an ai agent
- book hotels programmatically
- connect an llm agent to flight search via mcp
- find free-cancellation hotel rates with pay-later
- compare flight prices across airlines without markup
- integrate travel booking into a python or nodejs app
- hold a hotel room now and pay the balance later

## When to choose
- you want an AI agent to search and book real flights and hotels end-to-end
- you need MCP, CLI, or SDK access to travel inventory rather than scraping
- you want free-cancellation hotel rates with deferred payment
- you care about no-markup pricing and per-flight reliability history

## When to avoid
- you need a fully self-hosted travel search engine - the engine is server-side and proprietary
- you need high-volume commercial API access without prepaid-balance terms
- you require a permissive open-source license for the core platform (license is custom, SDKs are MIT)
- you only need human-facing travel browsing without agent/API integration
