## 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.

**Odessia.** Odessia is a free travel concierge that books as a registered travel agent, watches prices and award seats, and keeps a public status page with a clean record since July. No outside agent can call it, standing authorisations let it pay without asking each time, and no changelog was found.

## 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

### Odessia

1. Don't plan to call Odessia from another agent. It answers only its signed-in owner on the web, by message or by email.
2. Check whether the owner has set a standing authorisation before assuming a booking will wait for approval.
