Connects Claude to EnergyAI's assessment engine for residential and commercial energy upgrades. You get tools to calculate Energy Node Scores (0-100 across efficiency, electrification, resilience, and production), retrieve personalized solar, heat pump, and battery recommendations, pull state and utility incentives via DSIRE integration, and sanity-check installer quotes. The API costs $0.0402 per call. Reach for this when you're building chatbots or agents that need to advise on decarbonization pathways, estimate payback periods, or help users sequence upgrades from heat pumps to storage. The scoring model considers property characteristics and local utility rates to prioritize the highest-leverage move first.
