Which one, for what

  • 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

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

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.
