{"jsonrpc":"2.0","id":1,"method":"tools/list"}current_conditions — Latest instantaneous (real-time) readings for one or more USGS gauge sites. Returns the most recent value per site × parameter — e.g. current streamflow and gage height for a river. Common parameter codes: 00060 = discharge/streamflow (ft³/s), 00065 = gage height (ft), 00010 = water temperature (°C), 00045 = precipitation (in), 00095 = specific conductance, 00300 = dissolved oxygen, 63680 = turbidity. Keyless.daily_values — Daily-values time series for a single USGS site + parameter over a date range. Returns one statistic per day (default mean). Useful for trends, hydrographs, and historical comparison. Common statCd: 00003 = mean, 00001 = max, 00002 = min. Common parameter codes: 00060 = discharge (ft³/s), 00065 = gage height (ft), 00010 = water temperature (°C). Keyless.find_sites — Discover active USGS gauge sites in a US state that are currently reporting a given parameter (real-time). Returns sites with their latest reading; useful for finding which gauges are live in a region. Can match many sites, so results are capped. Keyless.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
