The hosted MCP uses OAuth 2.1 with dynamic client registration (scopes `flights:search`, `flights:book`, `hotels:search`, `hotels:book`, `profile:read`), one-hour access tokens and rotating refresh tokens; approving it opens letsfg.co/connect, and a card is only asked for at the first booking through a 0.00 Revolut set-up. The REST API takes an `X-API-Key` (`letsfg_...`) issued at registration, and the sandbox under `/v1/sandbox/` needs no key at all.",

      "pricingNotes": "Search is billed look-to-book. Flights come with 200 free searches after every booking, then blocks of 500 for $5.00 ($0.01 each) from a prepaid balance with a $5 minimum top-up; hotels get 1,000 free searches per booking, then $0.005 each. A search that returns nothing or fails doesn't count. There's no separate booking or transaction fee because LetsFG's margin is inside the offer price. For hotels that's the supplier's cost plus 6.4 per cent (Revolut Pay or an EEA card) or 8.3 per cent (a card issued elsewhere); the flight margin isn't published. Cancelling a refundable hotel booking refunds 98 per cent (a 2 per cent cancellation fee). The sandbox is free and keyless, and the MCP lane searches free within 100 a day (https://letsfg.co/developers, https://github.com/LetsFG/LetsFG/blob/main/skills/hotel-search/SKILL.md).",

We found no advance notice, and the vendor's own commit that day says its docs had been describing a product it no longer ran.

Tickets are bought by a LetsFG booking agent after the hold, 4 to 11 minutes per the docs, and bookings can pause with questions.\n\n**Skyscanner Travel APIs.** Thirteen documented search APIs cover flights, hotels and car hire behind one `x-api-key` header, with default rate limits published per endpoint and no usage fee. Access needs an approved application, an audience above 100,000 monthly users and a commercial agreement, and the usage guidelines bar live-price calls made without a user action. Booking happens on supplier sites.\n\n## Before you call either\n\n### LetsFG\n\n1. Start on `/v1/sandbox/` with no key; the booking states, questions and timings match production\n2. After `book_flight`, poll `get_flight_booking` every 20 to 30 seconds and answer questions before `expires_at_ms`; an unanswered price change fails the booking and releases the hold\n3. Honour `retry_after_seconds` on a 429. Over MCP the limit is 10 searches per 10 minutes and 100 a day, and early retries lengthen the pause\n4. Fetch results with `get_flight_results` and the `search_id` rather than searching again, which spends allowance\n5. Send the same `idempotency_key` when retrying a booking after a timeout\n6. Treat a 410 as a retired route and read the replacement path in its body\n\n### Skyscanner Travel APIs\n\n1. Send the key in the `x-api-key` header on every call to `https://partners.api.skyscanner.net`. CORS is not supported, so call from a server\n2. Create a live search only when a user has given origin, destination and exact dates. Use the indicative price endpoints for open-ended questions\n3. Poll `/search/poll/{sessionToken}` until `status` is `RESULT_STATUS_COMPLETE`, and replace earlier results only when `action` is `RESULT_ACTION_REPLACED`\n4. Start a new session when a poll returns 400. Flight session tokens last about an hour and hotel sessions at most 15 minutes\n5. Pass each `deepLink` to the traveller unchanged, since altered encoding breaks Impact tracking, and never put personal data in `subid2`\n\n## Questions\n\n### Which is better for AI agents, LetsFG or Skyscanner Travel APIs?\n\nLetsFG scores 64 (B) on agent readiness against Skyscanner Travel APIs's 45.6 (E), and leads in every scored category.\n\n### Which is cheaper for travel flights, LetsFG or Skyscanner Travel APIs?\n\nSkyscanner Travel APIs, at free against $0.01 per call for LetsFG.
