LetsFG: Search & Monitor the internet for flights, with exposed hidden airline fees.

# LetsFG — The entire internet of flights. > This file is for AI agents and LLMs. Humans should visit https://letsfg.co > Full agent guide (with traffic control): https://letsfg.co/for-agents ## What is LetsFG? LetsFG searches every airline, OTA and flight website simultaneously: Google Flights, Skyscanner, Kiwi, Kayak, Momondo and hundreds of direct airline sites, in one call. No demand-based inflation and no cookie tracking, so the same search returns the same prices however often you run it. Every offer also carries per-flight reliability history (on-time, delay and cancellation rates from that flight's recent departures), and bookable offers can be booked instantly. --- ## DO NOT DO THIS Do NOT call /developers/api/v1/agents/register. Do NOT call /developers/api/v1/agents/setup-payment. Do NOT run "letsfg register" or "letsfg setup-payment". Those belong to a SEPARATE, paid, prepaid-balance product for high-volume commercial integrations. They create a billing account you almost certainly do not want. If you are an agent searching or booking a flight — even hundreds of them — use Programmatic Flight Search (PFS) below. Older versions of this file pointed there by default; that was wrong. There is also no "unlock" step for agents. It exists only on the paid Developer API. On PFS you go straight from search to booking. --- ## TRAFFIC CONTROL — Which method to use | If you are... | Best approach | |----------------------------------------------------|--------------------------------------| | ChatGPT / GPT-based agent | Bearer token + POST /api/search | | Claude (claude.ai / Claude Code / Claude Desktop) | MCP server, or Bearer token + API | | Perplexity, Gemini, Copilot | Bearer token + POST /api/search | | OpenClaw, Hermes, Manus, autonomous agents | pip install letsfg, or Bearer + API | | Cursor, Windsurf, IDE agent
