## Which one, for what

### LiteAPI (Nuitee Connect) (D)

Good for: A builder who wants an agent to book hotels this week without a contract, and to earn a margin on them.

Ahead on:
- Reliability, 62 against 45
- Agent ergonomics, 86 against 69
- Payments & pricing, 40 against 10

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: Hosted MCP's documented setup puts the API key in the URL query string and exposes 111 generated tools

### 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:
- Security & auth, 41 against 33
- Maintenance & community, 65 against 48
- Transparency & trust, 56 against 43

Also in its favour:
- No incidents deducted, where LiteAPI (Nuitee Connect) loses 6 points for them

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

## Verdicts

**LiteAPI (Nuitee Connect).** Sandbox key at sign-up, same base URL as production, no card. Hosted MCP's documented setup puts the API key in the URL query string and exposes 111 generated tools.

**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.

## Before you call either

### LiteAPI (Nuitee Connect)

1. Use `/hotels/rates` with a short `hotelIds` list from `/data/hotels`; a broad rates call is slow and large
2. Always prebook before book and read the cancellation policy in the prebook response, since refundability differs per rate
3. Send a unique `clientReference` on book; a repeat returns error 4005 instead of a second booking
4. Set `margin` explicitly on every rates call. Zero means net rates with no commission to you
5. Send the key to the MCP in an `X-Api-Key` header rather than `?apiKey=` where the client allows it

### 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.
