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**Lola.** Free membership and published paid-plan commitments. External agent integration was not verified.\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### Lola\n\n1. Have the traveller confirm booking details, charges and cancellation terms.\n2. Check whether a membership benefit is live before relying on it.\n\n## Tutorials\n\n- [Test a flight search with LetsFG sandbox](https://www.anchorterminal.com/tutorials/letsfg/), for LetsFG\n\n## Questions\n\n### Which is better for AI agents, LetsFG or Lola?\n\nLetsFG scores 64 (B) on agent readiness against Lola's 15.1 (F), and leads in every scored category.\n\n### Can an agent call LetsFG and Lola without installing anything?\n\nLetsFG has a hosted endpoint at https://letsfg.co/developers/api/v1.
