No OpenAPI document, llms.txt or official MCP server. **Hotelbeds Hotel Booking API.** Free evaluation key on registration, no card and no sales call. 50 requests a day on evaluation, and the 51st returns a 403. ## Before you call either ### Duffel Flights and Stays API 1. Send `Duffel-Version: v2` on every request or you get a version error 2. Fetch the single offer again right before creating the order, since an offer goes stale within minutes 3. Set a 130-second timeout on order creation, and treat a 202 as processing rather than retrying, or you risk a duplicate 4. Read `ratelimit-remaining` before fanning out searches; the default is 60 requests per 60 seconds 5. Count offer requests. Above 1,500 per order the surcharge starts and the agreement lets Duffel cap you ### Hotelbeds Hotel Booking API 1. Compute `X-Signature` fresh per request from key, secret and the current epoch seconds, in that order 2. Budget the 50 daily evaluation calls; cache hotel content and only call availability for real dates 3. Run CheckRate on a rate before booking when the availability response says it needs rechecking 4. Read a 403 on the test host as the daily quota first, not a bad key 5. Simulate a cancellation before running it ## Other comparisons with Duffel Flights and Stays API or Hotelbeds Hotel Booking API - [Booking.com Demand API vs Duffel Flights and Stays API](https://www.anchorterminal.com/compare/booking-demand-api-vs-duffel.md) - [Booking.com Demand API vs Hotelbeds Hotel Booking API](https://www.anchorterminal.com/compare/booking-demand-api-vs-hotelbeds.md) - [Duffel Flights and Stays API vs Expedia Group Rapid API](https://www.anchorterminal.com/compare/duffel-vs-expedia-rapid.md) - [Expedia Group Rapid API vs Hotelbeds Hotel Booking API](https://www.anchorterminal.com/compare/expedia-rapid-vs-hotelbeds.md) - [Hotelbeds Hotel Booking API vs LetsFG](https://www.anchorterminal.com/compare/hotelbeds-vs-letsfg.md) - [Hotelbeds Hotel Booking API vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/hotelbeds-vs-liteapi.md) - [Duffel Flights and Stays API vs FlightClaw](https://www.anchorterminal.com/compare/duffel-vs-flightclaw.md) - [Duffel Flights and Stays API vs LetsFG](https://www.anchorterminal.com/compare/duffel-vs-letsfg.md) - [Duffel Flights and Stays API vs LiteAPI (Nuitee Connect)](https://www.anchorterminal.com/compare/duffel-vs-liteapi.md) - [FlightClaw vs Hotelbeds Hotel Booking API](https://www.anchorterminal.com/compare/flightclaw-vs-hotelbeds.md)
