Tickets are bought by a LetsFG booking agent after the hold, 4 to 11 minutes per the docs, and bookings can pause with questions.\n\n## Before you call either\n\n### FlightClaw\n\n1. Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move\n2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking\n3. Never ask for card numbers in chat. Hand over `checkout_url`, or pay it with a Link virtual card the user approved for the exact total\n4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches\n5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details\n\n### LetsFG\n\n1. Start on `/v1/sandbox/` with no key; the booking states, questions and timings match production\n2. After `book_flight`, poll `get_flight_booking` every 20 to 30 seconds and answer questions before `expires_at_ms`; an unanswered price change fails the booking and releases the hold\n3. Honour `retry_after_seconds` on a 429. Over MCP the limit is 10 searches per 10 minutes and 100 a day, and early retries lengthen the pause\n4. Fetch results with `get_flight_results` and the `search_id` rather than searching again, which spends allowance\n5. Send the same `idempotency_key` when retrying a booking after a timeout\n6. Treat a 410 as a retired route and read the replacement path in its body\n\n## Other comparisons with FlightClaw or LetsFG\n\n- [Booking.com Demand API vs LetsFG](https://www.anchorterminal.com/compare/booking-demand-api-vs-letsfg.md)\n- [Expedia Group Rapid API vs LetsFG](https://www.anchorterminal.com/compare/expedia-rapid-vs-letsfg.md)\n- [Hotelbeds Hotel Booking API vs LetsFG](https://www.anchorterminal.com/compare/hotelbeds-vs-letsfg.md)\n- [Duffel Flights and Stays API vs FlightClaw](https://www.anchorterminal.com/compare/duffel-vs-flightclaw.md)\n- [Duffel Flights and Stays API vs LetsFG](https://www.anchorterminal.com/compare/duffel-vs-letsfg.md)\n- [FlightClaw vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/flightclaw-vs-liteapi.md)\n- [LetsFG vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/letsfg-vs-liteapi.md)\n- [Booking.com Demand API vs FlightClaw](https://www.anchorterminal.com/compare/booking-demand-api-vs-flightclaw.md)\n- [Expedia Group Rapid API vs FlightClaw](https://www.anchorterminal.com/compare/expedia-rapid-vs-flightclaw.md)\n- [FlightClaw vs Hotelbeds Hotel Booking API](https://www.anchorterminal.com/compare/flightclaw-vs-hotelbeds.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "FlightClaw vs LetsFG", "url": "" } ], "description": "LetsFG has a score of 64.2 (B) against FlightClaw's 45.5 (E).
