Letsfg

What is LetsFG?

LetsFG is an agent-native travel search tool that finds the cheapest flights across 75 airline connectors and enterprise GDS sources (Amadeus, Duffel, Sabre, Travelport) in roughly 5–10 seconds. It returns raw airline prices with no markup, tracking, or cookies. It is designed for AI agents (OpenClaw, Perplexity Computer, Manus, Claude Code, Codex, Cursor, Windsurf) as well as direct CLI, MCP, and SDK use.

How to use LetsFG?

Install the Python package with pip install letsfg and optionally playwright install chromium for browser-based connectors. Then run CLI commands (e.g., letsfg search-local LHR BCN 2026-04-15) or use the Python/JS SDK. For MCP integration, add the letsfg-mcp server to your MCP config. Registration for an API key is optional but recommended for access to enterprise GDS sources (400+ airlines) and booking features.

FAQ from LetsFG

How do I install LetsFG?

Run pip install letsfg and then playwright install chromium for local connectors. No account or API key is needed for basic local search.

What dependencies or runtime does it require?

Python 3+ and Playwright for browser‑based connectors. The JS SDK and MCP server do not require Playwright.

How is LetsFG different from Google Flights or other OTAs?

LetsFG returns raw airline prices with no cookies, demand tracking, or markup. It is also faster (5–10 seconds vs 30+ seconds) and works directly inside AI agents.

Where does flight data come from?

Local connectors run on your machine and scrape airline websites directly. With an API key, the cloud backend also queries enterprise GDS/NDC providers (Amadeus, Duffel, Sabre, Travelport, Kiwi) and merges results.

What transports and authentication does LetsFG support?

CLI, Python SDK, JS SDK, and MCP. Authentication is optional – local search works without an API key; unlocking and booking require a free registered API key.
