langgraph-weather-hotel-flight-agent

Plan a route trip with a modular LangGraph agent graph that runs weather → cache → live LLM search → flight-API enrich → store → recommend. Give an origin, destination, dates, bedrooms, max price-per-night, and a minimum hotel rating; get back a destination weather summary, the top rating-then-price hotels, and the cheapest flight options, with results cached in SingleStore so repeat routes return instantly. Use when you want a reproducible, modular agentic travel pipeline (not a one-shot chatbot) and want to extend or swap individual agent nodes.
