We're LetsFG — a community of travelers.

Finding a flight shouldn't mean checking 47 websites. Or 3 hours of searching.

Or having that feeling you could've got a better deal if you'd just waited a little longer.

So we built something about it.

No markup. No tracking. No price that goes up because you looked twice.

Join the community. Help others find cheaper flights. Spread the word.

400+ airlines. Real prices. One function call.

LetsFG gives your AI agent flight search and booking superpowers. 200+ connectors fire in parallel on your machine, scanning the entire world for the cheapest price. Zero markup. Real airline tickets.

The same flight costs $20–$50 less because you skip OTA inflation, cookie tracking, and surge pricing.

Three ways to use LetsFG

• Local (Path 1): Fires 200+ airline connectors on your machine via Playwright. Free, unlimited, no API key required. Results include offer_ref and payment_token fields. Booking links are masked by default — use the concierge flow or the Developer API to get the direct airline URL (see below).
• letsfg.co (Path 2): Purpose-built for agents (OpenClaw, Claude, GPT, etc.) and humans who need instant results without installing anything. Search is free. To get the direct booking link, call POST https://letsfg.co/api/developers/checkout with the offer_id, offer_ref, payment_token, and price — this returns a Stripe checkout URL. After the user or agent pays the 1% fee (min $3.00), poll GET https://letsfg.co/api/developers/payment-verify?token={payment_token} until verified: true to receive the booking_url.
• Developer API (Path 3): Server-side search at letsfg.co/developers with prepaid credits. Returns direct airline booking URLs with no concierge fee and no per-booking checkout layer. Best for teams and products at volume.

Concierge fee vs. Developer API: The 1% concierge fee (min $3) applies only when unlocking offers via the letsfg.co website or agent API (Path 2). If you want direct airline URLs without any per-booking fee, sign up for the Developer API at letsfg.co/developers.

Real prices: LetsFG vs Google Flights

We searched 5 routes on Google Flights and LetsFG on the same day (June 15, 2026). Same airline, same itinerary — LetsFG was cheaper every time:

$116 saved across 6 flights. Google Flights inflates further on repeat searches. LetsFG returns the raw airline price every time.

Why the difference? Google Flights only searches its own limited set of airline partners. LetsFG searches everywhere — 200+ connectors including Skyscanner, Kiwi, Kayak, Momondo, plus direct airline websites (Ryanair, United, Southwest, EasyJet, Spirit, Norwegian, AirAsia, and 190+ more). More sources = better prices. And unlike travel websites, LetsFG returns the raw price with zero markup, no tracking, no inflation.

Pricing

Local = 100% free, personal use. The CLI, Python SDK, npm packages, and local MCP server run 200+ connectors covering 400+ airlines on your machine. No API key needed, no fees, no limits. Searches take 1–15 minutes depending on how many connectors run.

Developer API = prepaid, business use. letsfg.co/developers runs searches server-side — no local Playwright, no wait, results in seconds. Built for products and teams. Prepaid credits.

letsfg.co = free search + small unlock fee. Search is free, and when you unlock a search you get the booking links for all flights from that search. Purpose-built for agents (OpenClaw etc.) that can't run local browser automation.

Works everywhere your agent runs

MCP Server (Claude Desktop / Cursor / Windsurf / OpenClaw)

  "mcpServers": {
    "letsfg": {
      "command": "npx",
      "args": ["-y", "letsfg-mcp"]

}

That's it — search works immediately, no API key needed. 200+ connectors covering 400+ airlines run locally.

If you cloned the repo or run the SDK locally, stay on this path. You do not need to register for the paid public developer API to use local connectors, and local searches can still feed analytics and telemetry.
