Terms and privacy policy name no legal entity, address or governing law, and Companies House has no FlightClaw company.\n\n**Trainline.** Official partner API covers booking and aftersales. Partner approval and integration required.\n\n## Before you call either\n\n### FlightClaw\n\n1. Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move\n2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking\n3. Never ask for card numbers in chat. Hand over `checkout_url`, or pay it with a Link virtual card the user approved for the exact total\n4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches\n5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details\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## Questions\n\n### Which is better for AI agents, FlightClaw or Trainline?\n\nFlightClaw scores 45.3 (E) on agent readiness against Trainline's 8.6 (F), and leads in every scored category.\n\n### Do FlightClaw and Trainline need an API key?\n\nFlightClaw uses an OAuth sign-in.
