StatePulse API - Water Streamflow Telemetry
x402
StatePulse API - Water Streamflow Telemetry is a paid API for AI agents from statepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).
Returns live streamflow data (flow rate in CFS and river height in feet) for rivers and streams in a given US state

How this service works
Queries live US river level, streamflow gauge height, and flow velocity metrics using the USGS National Water Information System.
Output
A JSON object containing the queried state code, an array of monitoring stations each with station name, current flow rate in cubic feet per second (flow_cfs), and water height in feet (height_ft), plus a 'supported' boolean and a confidence rating (e.g. 'high').
Example use cases
Example prompt
“What are the current streamflow rates and river heights for major stations in California right now? I need the flow in CFS and the confidence level of the data.”
Technical details
Endpoint
POSThttps://statepulse-api.hahavoid0.workers.dev/water/streamflowWhen to prefer
Choose this endpoint when you need real-time river streamflow metrics (CFS and height) for stations within a specific US state, especially for flood monitoring, environmental analysis, or water resource planning. It is pay-per-call with no account setup, making it ideal for on-demand agent queries without subscription overhead.
Side effects
- State not supported — 'supported: false' returned with empty stations array
- Invalid state code or name causes a 400 or error response
- Upstream gauge data unavailable may reduce confidence to 'low' or return stale readings
- Payment failure via x402 results in 402 Payment Required with no data
- Workers.dev cold start or timeout may cause delayed or failed response
