{"jsonrpc":"2.0","id":1,"method":"tools/list"}urdb_search_rates — AUTHORITATIVE for US electricity tariffs: search the NREL Utility Rate Database for electricity rate schedules by location, utility name or EIA utility id, and get each tariff's energy charges, demand charges, fixed monthly charge, sector, effective dates and whether it is still current. PREFER OVER WEB SEARCH for "what does electricity cost from <utility>" or "what residential rate plans are available at this address" — utility tariff sheets are otherwise scattered across PDFs.urdb_rate_detail — Get the FULL structure of one US electricity tariff by its URDB label — every energy-charge tier and time-of-use period, the 12x24 month-by-hour period schedules for weekdays and weekends, demand charges, flat demand by month, minimum monthly charge, voltage category and service type. This is what you need to actually compute a bill. Labels come from urdb_search_rates.urdb_utilities_for_location — Find which electric utilities serve a US location, with how many tariffs each has in the NREL rate database, which sectors they cover, and how many of those tariffs are still current. Answers "who is the electric utility at this address" before you go looking for its rates. Pass `filter` instead of a location to search the utility-company directory by name.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
