• GET /api/water/gauge — Live USGS river-gauge tick, deterministic. Answers "what is the flow at this gauge right now", "is this river high or low vs this week". Returns the latest streamflow (discharge, cfs) and gage height (ft) for one USGS site plus the 7-day min/max range, reading count, site name and coordinates, straight from USGS instantaneous values. Unknown sites 404 before payment. No LLM, no key, public domain. (0.01 USDC on Base)
• GET /api/water/streamflow — Real-time streamflow for water and hydrology agents. Returns current flow conditions, flood-stage context, and low-flow drought signals from USGS gauge stations. (0.05 USDC on Solana)
• GET /api/water/aquifer — Aquifer system analysis for water and investor agents. Returns depletion rates, recharge capacity, agricultural dependency, regulatory outlook, and sustainability for Ogallala, Central Valley, Floridan, and 30+ US aquifers. (0.15 USDC on Base)
• GET /api/water/global-stress — Global water stress intelligence for risk and investor agents. Covers freshwater availability, groundwater depletion, transboundary conflict risk, and investment and operational implications for any region. (0.15 USDC on Base)
• GET /api/water/groundwater — Real-time groundwater levels for water and hydrology agents. Returns depth-to-water, trend analysis, and drought risk context from USGS monitoring wells for any US state. (0.08 USDC on Solana)
• GET /api/water/drought — US drought status for water and ag-trader agents. Returns drought category breakdown by area from the US Drought Monitor, a 12-week trend, and agricultural/municipal impact. (0.08 USDC on Solana)
• GET /api/water/agriculture-use — Agricultural water intelligence for grower and ag-trader agents. Returns irrigation demand, water-rights curtailments, and farm water cost, combining USGS groundwater, US Drought Monitor, and USDA data. (0.15 USDC on Solana)
• GET /api/water/supply-brief — Water supply intelligence for utility and investor agents. Covers reservoir storage, utility supply outlook, infrastructure investment, rate trajectory, drought restrictions, and a 5-year risk rating for any US city or region. (0.5 USDC on Base)
• GET /api/water/flood-risk — Real-time flood risk for insurance and emergency-planning agents. Combines USGS stream gauges, Open-Meteo precipitation forecasts, and FEMA flood-zone context into current river conditions and actionable guidance. (0.15 USDC on Solana)
• GET /api/water/quality — Water quality intelligence for water and utility agents. Returns contaminant levels, pH, dissolved oxygen, temperature, and drinking-water compliance from EPA Water Quality Portal and USGS. (0.08 USDC on Base)
• GET /api/water/supply-snapshot — Deterministic water-supply numbers snapshot for a US state — latest USGS groundwater well readings (depth-to-water) and current US Drought Monitor D0-D4 breakdown. No LLM, no web search. The $0.50 /api/water/supply-brief adds reservoir storage, utility outlook, restrictions, rate trajectory, and a synthesized 5-year risk rating. (0.25 USDC on Base)
