No OpenAPI document, llms.txt or official MCP server.\n\n**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.\n\n## Before you call either\n\n### Duffel Flights and Stays API\n\n1. Send `Duffel-Version: v2` on every request or you get a version error\n2. Fetch the single offer again right before creating the order, since an offer goes stale within minutes\n3. Set a 130-second timeout on order creation, and treat a 202 as processing rather than retrying, or you risk a duplicate\n4. Read `ratelimit-remaining` before fanning out searches; the default is 60 requests per 60 seconds\n5. Count offer requests. Above 1,500 per order the surcharge starts and the agreement lets Duffel cap you\n\n### Odessia\n\n1. Don't plan to call Odessia from another agent. It answers only its signed-in owner on the web, by message or by email.\n2. Check whether the owner has set a standing authorisation before assuming a booking will wait for approval.\n\n## Tutorials\n\n- [Compare test flight fares with Duffel](https://www.anchorterminal.com/tutorials/duffel/), for Duffel Flights and Stays API\n\n## Questions\n\n### Which is better for AI agents, Duffel Flights and Stays API or Odessia?\n\nDuffel Flights and Stays API scores 66.7 (B) on agent readiness against Odessia's 22.2 (F), and leads in every scored category.\n\n### Which is cheaper for flight search, Duffel Flights and Stays API or Odessia?\n\nOdessia, at free against $3 per transaction for Duffel Flights and Stays API.
