## 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.

**Soar.** Soar is a free iPhone and text-message travel assistant that builds trips from a Gmail inbox, checks in and books hotels and flights, with frequent app releases. Its agent stack, Soar MCP, is private, and its terms predate booking and don't name the 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

### Soar

1. Don't plan to call Soar from another agent. Its MCP server needs private onboarding by the team.
2. Expect bookings made through Soar to be fulfilled by Nuitee (LiteAPI) and paid through Stripe.
