# WaterPulse Agricultural Water Intelligence

> WaterPulse Agricultural Water Intelligence is a paid API for AI agents from waterpulse-henna.vercel.app, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Returns irrigation demand forecasts, water-rights curtailments, and farm water cost estimates for a given agricultural area by combining USGS groundwater, US Drought Monitor, and USDA data.

## Facts

- Endpoint: GET https://waterpulse-henna.vercel.app/api/water/agriculture-use
- Price: $0.15/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/waterpulse-agricultural-water-intelligence-cd839561
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_2SAiK_qlwRQCrXREC_Pbp

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability waterpulse-agricultural-water-intelligence-cd839561
```

Example prompt: What's the current irrigation demand, any water-rights curtailments, and estimated farm water cost for agricultural operations in Fresno County, California right now?

## When to prefer this

Use this endpoint when an agent needs combined agricultural water intelligence — specifically the intersection of irrigation demand, water-rights curtailment status, and farm water cost — for US agricultural regions. Prefer this over generic drought or streamflow endpoints when the user is a grower, ag-trader, or farm operator who needs actionable water economics data, not just raw hydrological readings.

## Known failure modes

- Region not covered by USGS or USDA data sources — returns 404 or empty dataset
- Invalid or unrecognized geographic parameter — returns 400 bad request
- Upstream data source temporarily unavailable (USGS or Drought Monitor outage) — returns 503
- Rate limit or payment failure via x402 — returns 402 payment required
- No current curtailment data available for the requested region — returns partial results

## How this service works

Real-time water intelligence API. Groundwater levels, streamflow, drought status, water quality, aquifer analysis, flood risk, and global water stress — pay-per-query via x402.

## Output

Returns structured data including current irrigation demand levels, active water-rights curtailment notices, and estimated farm water costs for the queried region, sourced from USGS groundwater readings, US Drought Monitor drought categories, and USDA agricultural water data.
