It can't book, hold, change or cancel, and it has no published rate limits, changelog, terms or version. Each search returns 15 itineraries with no way to ask for fewer.\n\n## Before you call either\n\n### Hotelbeds Hotel Booking API\n\n1. Compute `X-Signature` fresh per request from key, secret and the current epoch seconds, in that order\n2. Budget the 50 daily evaluation calls; cache hotel content and only call availability for real dates\n3. Run CheckRate on a rate before booking when the availability response says it needs rechecking\n4. Read a 403 on the test host as the daily quota first, not a bad key\n5. Simulate a cancellation before running it\n\n### Kiwi.com MCP Server\n\n1. POST to `https://mcp.kiwi.com` itself. `/mcp` returns 404, and responses arrive as `text/event-stream` even for a single reply\n2. Send dates as dd/mm/yyyy and set `currency`, which defaults to EUR\n3. Check the `error` field of every result. A rejected input returns `resultsCount` 0 with `isError` false\n4. Narrow with `price_to`, `max_sector_stopovers` and `sort`. There is no limit parameter and each search returns 15 itineraries\n5. Give the user `bookingUrl` to book. Don't call `feedback-to-devs` with user data, because it sends free text to Kiwi.com\n\n## Questions\n\n### Which is better for AI agents, Hotelbeds Hotel Booking API or Kiwi.com MCP Server?\n\nKiwi.com MCP Server scores 51.9 (D) on agent readiness against Hotelbeds Hotel Booking API's 36.3 (F), and leads in 6 of 7 scored categories.\n\n### Do Hotelbeds Hotel Booking API and Kiwi.com MCP Server need an API key?\n\nHotelbeds Hotel Booking API needs an API key.
