# WaterPulse Supply Brief

> WaterPulse Supply Brief is a paid API for AI agents from waterpulse-henna.vercel.app, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Returns a water supply intelligence brief for any US city or region, covering reservoir storage, utility outlook, infrastructure investment, rate trajectory, drought restrictions, and a 5-year risk rating.

## Facts

- Endpoint: GET https://waterpulse-henna.vercel.app/api/water/supply-brief

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-supply-brief-1ce5e7a7
```

Example prompt: Give me a full water supply brief for Phoenix, Arizona — I want reservoir storage, the utility supply outlook, any drought restrictions in effect, rate trajectory, and the 5-year risk rating so I can assess it for a long-term infrastructure investment.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-dimensional water supply intelligence brief for a specific US city or region — especially for utility planning, real estate investment due diligence, infrastructure risk assessment, or drought policy research. Prefer this over drought-only or streamflow-only endpoints when you need the full picture including rates, infrastructure investment signals, and a forward-looking 5-year risk score.

## Known failure modes

- Location not recognized or outside US coverage — returns error or empty result
- No recent data available for the specified region — may return stale or partial data
- Rate limit or payment failure via x402 — returns 402 Payment Required
- Ambiguous city name with multiple matches — may return results for wrong municipality

## How this service works

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.

## Output

A structured water supply intelligence brief including current reservoir storage levels, utility supply outlook, infrastructure investment signals, water rate trajectory, active drought restrictions, and a 5-year water risk rating for the requested US city or region.
