AI Trip-Planning Engine

1 endpoint — One form in, three trips out

A travel startup had the frontend for an AI trip-planning product but nothing behind it. We built the whole engine on Make.com + OpenAI + Booking.com data via RapidAPI, called by their Lovable frontend through one webhook. A traveler's request (destination, dates, group size, budget, preferences) is validated and priced-out before any paid API call runs; the budget is split into three coherent profiles (Comfort, Balanced, Explore); real hotels are fetched live from booking data for the exact dates/group/currency (ranked, priced, with working links); and OpenAI writes a personalized day-by-day itinerary plus a one-line rationale per option — all assembled into one strict, predictable JSON response the frontend renders instantly. The split is deliberate: AI does the imaginative planning, live data covers everything a traveler can act on, so the product stays trustworthy. Runs in the client's own accounts; portfolio figures are a demo traveler.
