Send `Duffel-Version: v2` on every request or you get a version error\n2. Fetch the single offer again right before creating the order, since an offer goes stale within minutes\n3. Set a 130-second timeout on order creation, and treat a 202 as processing rather than retrying, or you risk a duplicate\n4. Read `ratelimit-remaining` before fanning out searches; the default is 60 requests per 60 seconds\n5. Count offer requests. Above 1,500 per order the surcharge starts and the agreement lets Duffel cap you\n\n### LiteAPI (Nuitee Connect)\n\n1. Use `/hotels/rates` with a short `hotelIds` list from `/data/hotels`; a broad rates call is slow and large\n2. Always prebook before book and read the cancellation policy in the prebook response, since refundability differs per rate\n3. Send a unique `clientReference` on book; a repeat returns error 4005 instead of a second booking\n4. Set `margin` explicitly on every rates call. Zero means net rates with no commission to you\n5. Send the key to the MCP in an `X-Api-Key` header rather than `?apiKey=` where the client allows it\n\n## Other comparisons with Duffel Flights and Stays API or LiteAPI (Nuitee Connect)\n\n- [Booking.com Demand API vs Duffel Flights and Stays API](https://www.anchorterminal.com/compare/booking-demand-api-vs-duffel.md)\n- [Booking.com Demand API vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/booking-demand-api-vs-liteapi.md)\n- [Duffel Flights and Stays API vs Expedia Group Rapid API](https://www.anchorterminal.com/compare/duffel-vs-expedia-rapid.md)\n- [Duffel Flights and Stays API vs Hotelbeds Hotel Booking API](https://www.anchorterminal.com/compare/duffel-vs-hotelbeds.md)\n- [Expedia Group Rapid API vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/expedia-rapid-vs-liteapi.md)\n- [Hotelbeds Hotel Booking API vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/hotelbeds-vs-liteapi.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", "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": "Duffel Flights and Stays API vs LiteAPI (Nuitee Connect)", "url": "" } ], "description": "Duffel Flights and Stays API has a score of 66.9 (B) against LiteAPI (Nuitee Connect)'s 53.5 (D).
