Know whether electricity is cheap or expensive at U.S. addresses, right now, without parsing a tariff PDF or image file.
TOU schedules are fragmented across hundreds of utilities, buried in tariff PDFs, and constantly changing. Our API makes it one call.
Pass any U.S. address or ZIP — no setup or configuration required.
We auto-detect the right utility and active TOU schedules for that location.
Receive peak, off-peak, and other statuses, plus the next period name and its start time.
tou.tools ships as an MCP server. Any AI agent with MCP support can query real-time TOU data without writing a line of integration code — no SDK, no auth plumbing, no schedule parsing. Plug it into Claude, ChatGPT, or any open-source agent framework and your agent knows the grid.
Side projects and weekend builds. A generous free tier, a simple REST API, and no credit card required — start querying TOU periods in minutes.
Bring TOU awareness to Home Assistant, custom automations, and home energy dashboards. Reliable schedule data keeps every smart-home action in sync with the active period.
LLM-powered agents that query TOU status natively over MCP. First-class agent support, zero integration boilerplate, and works with any MCP-compatible runtime.
Cut demand charges across a portfolio of buildings. Know the active TOU period at every site so HVAC, lighting, and process loads shift off-peak automatically — whether you run 10 locations or 1,500.
Time dispatch for home and grid-scale batteries. Accurate current periods and forward schedules let you charge through off-peak and discharge when it counts most.
Optimize charge timing across a fleet of chargers in multiple service territories. High-volume queries and real-time period changes keep charging on off-peak at scale.
tou.tools speaks your language. Read the plain-text briefing we wrote for LLMs, or connect over MCP and call it as a native tool.
