Managed Affiliate Partner status required; no self-serve key.\n\n**ETG API (RateHawk).** Hotel search and booking are documented in a public Swagger 2.0 file, an llms.txt index and a changelog with 64 dated entries in 2026. Access is by contract. Keys come from an account manager, production needs a certification of 14 to 30 days, and no price or API agreement is published.\n\n## Before you call either\n\n### Booking.com Demand API\n\n1. Send both `Authorization: Bearer` and `X-Affiliate-Id`, or the call fails on auth\n2. Stay under 50 requests a minute in the sandbox and back off exponentially on 429\n3. Only accommodation flows book in the sandbox; cars and attractions won't\n4. Store the key at creation, it's never shown again\n5. Use filters and pagination on search to keep payloads small\n\n### ETG API (RateHawk)\n\n1. Call `/api/b2b/v3/overview/` first. It lists the endpoints the key may use and each one's request limit.\n2. Keep sandbox IDs, keys and hashes inside `api-sandbox.ratehawk.com`. Sandbox region IDs are limited to 2011, 2395, 2734 and 6053839.\n3. Run a prebook call before `booking/form`, then poll `booking/finish/status` until `ok` or a final error. Treat `timeout`, `unknown` and 5xx as still in progress.\n4. Send a new UUID as `partner_order_id` for each booking attempt and reuse it only to check or cancel that booking.\n5. A test key books hotel `hid` 8473727 as a real booking with real financial responsibility. Cancel it afterwards.\n\n## Questions\n\n### Which is better for AI agents, Booking.com Demand API or ETG API (RateHawk)?\n\nETG API (RateHawk) scores 53 (D) on agent readiness against Booking.com Demand API's 38.1 (E), and leads in every scored category.\n\n### Do Booking.com Demand API and ETG API (RateHawk) need an API key?\n\nBoth need an API key.\n\n### Can an agent call Booking.com Demand API and ETG API (RateHawk) without installing anything?\n\nYes.
