## 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.
