## Verdicts

**Booking.com Demand API.** Search, look and book plus order management on Booking.com's accommodation inventory. Managed Affiliate Partner status required; no self-serve key.

**FlightClaw.** Hosted MCP at mcp.flightclaw.com/mcp with OAuth 2.1, PKCE and dynamic client registration, no API keys. Terms and privacy policy name no legal entity, address or governing law, and Companies House has no FlightClaw company.

## Before you call either

### Booking.com Demand API

1. Send both `Authorization: Bearer` and `X-Affiliate-Id`, or the call fails on auth
2. Stay under 50 requests a minute in the sandbox and back off exponentially on 429
3. Only accommodation flows book in the sandbox; cars and attractions won't
4. Store the key at creation, it's never shown again
5. Use filters and pagination on search to keep payloads small

### FlightClaw

1. Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move
2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking
3. 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
4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches
5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details
