No price, API rate limit, status page or SLA is published, and the terms bar automated tools without written permission. ## 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 ### Travelport TripServices APIs 1. Request one token and cache it for 24 hours. Travelport declines certification for refreshing more often than every 23 hours without a stated reason 2. Send `Accept-Encoding: gzip, deflate` and `XAUTH_TRAVELPORT_ACCESSGROUP` (or `TVP-PCC-CORE`) on every call. Production traffic without compression is refused 3. Send `offersPerPage` on a journey-based search, or later calls can't reference its results. Cached searches last 12 minutes for GDS content and 34 for NDC 4. Commit a workbench within 30 minutes or it expires, and read `Result/Error` in the body even on HTTP 200 5. Get written authorisation for agent access before production. The terms bar automated tools and speculative or duplicate bookings ## Questions ### Which is better for AI agents, Duffel Flights and Stays API or Travelport TripServices APIs?
