River and water-levels API — live USGS gages.

Real-time US river gage height and streamflow from USGS — a rising gage signals flood risk, low flow signals drought.

The call

Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.

# REST (free key)
curl -H "X-API-Key: $KEY" "https://dynamicfeed.ai/water-levels?state=TX"

# MCP (keyless) — point any client at https://dynamicfeed.ai/mcp, then call:
water_levels(state="TX")
