Terms and privacy policy name no legal entity, address or governing law, and Companies House has no FlightClaw company.\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### FlightClaw\n\n1. Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move\n2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking\n3. Never ask for card numbers in chat. Hand over `checkout_url`, or pay it with a Link virtual card the user approved for the exact total\n4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches\n5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details\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, FlightClaw or ETG API (RateHawk)?\n\nETG API (RateHawk) scores 53 (D) on agent readiness against FlightClaw's 45.3 (E), and leads in 4 of 7 scored categories.
