Verdicts

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.

Soar

Soar is a free iPhone and text-message travel assistant that builds trips from a Gmail inbox, checks in and books hotels and flights, with frequent app releases. Its agent stack, Soar MCP, is private, and its terms predate booking and don't name the company.

Before you call either

ETG API (RateHawk)

  1. Call /api/b2b/v3/overview/ first. It lists the endpoints the key may use and each one's request limit.
  2. Keep sandbox IDs, keys and hashes inside api-sandbox.ratehawk.com. Sandbox region IDs are limited to 2011, 2395, 2734 and 6053839.
  3. 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.
  4. Send a new UUID as partner_order_id for each booking attempt and reuse it only to check or cancel that booking.
  5. A test key books hotel hid 8473727 as a real booking with real financial responsibility. Cancel it afterwards.

Soar

  1. Don't plan to call Soar from another agent. Its MCP server needs private onboarding by the team.
  2. Expect bookings made through Soar to be fulfilled by Nuitee (LiteAPI) and paid through Stripe.
