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.

Trainline

Official partner API covers booking and aftersales. Partner approval and integration required.

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

Trainline

  1. Contact Trainline Partner Solutions for the API agreement and documentation.
  2. Keep ticket purchases and refunds behind the traveller’s approval.

From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
