Verdicts

Duffel Flights and Stays API

Self-serve sign-up and test mode with no card or contract. 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
