I've been building [CielStay](https://www.cielstay.com) — a semantic discovery platform for vacation rentals that finds properties by personality and vibe rather than checkboxes using a matching concept I call "Resonance". It's in alpha mode, but we have ~64K listings across 61 countries, cross-linking OTA (Airbnb, Vrbo, Booking.com) and direct sites. This service is currently 100% free.
I set up llms.txt at [cielstay.com/llms.txt](https://www.cielstay.com/llms.txt) with full API documentation so Claude agents could search our inventory. Then I tried to actually use it.
