## Which one, for what

### ETG API (RateHawk) (D)

Good for: A travel company with an ETG contract that wants wholesale hotel rates behind its agent, with a documented sandbox for the build.

Ahead on:
- Reliability, 45 against 5
- Schema & documentation, 85 against 0
- Agent ergonomics, 69 against 0
- Security & auth, 41 against 3
- Maintenance & community, 65 against 54
- Transparency & trust, 56 against 44

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No self-serve key. Registration is followed by a request to an account manager, and the docs say an agreement must be signed before use

### Soar (F)

Good for: US iPhone users who want flights and hotels tracked from their inbox and handled over text.

Ahead on:
- Payments & pricing, 20 against 10

Watch for: Soar MCP is private, with keys set up by hand after a request.

## 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.
