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.\n\n**Trainline.** Official partner API covers booking and aftersales. Partner approval and integration required.\n\n## Before you call either\n\n### ETG API (RateHawk)\n\n1. Call `/api/b2b/v3/overview/` first. It lists the endpoints the key may use and each one's request limit.\n2. Keep sandbox IDs, keys and hashes inside `api-sandbox.ratehawk.com`. Sandbox region IDs are limited to 2011, 2395, 2734 and 6053839.\n3. 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.\n4. Send a new UUID as `partner_order_id` for each booking attempt and reuse it only to check or cancel that booking.\n5. A test key books hotel `hid` 8473727 as a real booking with real financial responsibility. Cancel it afterwards.\n\n### Trainline\n\n1. Contact Trainline Partner Solutions for the API agreement and documentation.\n2. Keep ticket purchases and refunds behind the traveller’s approval.\n\n## Tutorials\n\n- [Check a RateHawk sandbox integration before booking](https://www.anchorterminal.com/tutorials/ratehawk/), for ETG API (RateHawk)\n\n## Questions\n\n### Which is better for AI agents, ETG API (RateHawk) or Trainline?\n\nETG API (RateHawk) scores 53 (D) on agent readiness against Trainline's 8.6 (F), and leads in every scored category.\n\n### Do ETG API (RateHawk) and Trainline need an API key?\n\nETG API (RateHawk) needs an API key.
