# WaterPulse US Drought Status

> WaterPulse US Drought Status is a paid API for AI agents from waterpulse-henna.vercel.app, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-13).

Returns US Drought Monitor drought category breakdown by area, 12-week trend, and agricultural/municipal impact for a given region.

## Facts

- Endpoint: GET https://waterpulse-henna.vercel.app/api/water/drought
- Price: $0.08/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/waterpulse-us-drought-status-f1271489
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_K7QcChN4CFA9houZZP3np

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-us-drought-status-f1271489
```

Example prompt: Can you pull the current US Drought Monitor status for Kansas — I need the drought category breakdown by area, the 12-week trend, and how it's affecting agricultural and municipal water supplies?

## When to prefer this

Choose this endpoint when you need official US Drought Monitor drought classification data including multi-week trends and sector-specific (agriculture/municipal) impact assessments. Prefer this over general weather or precipitation endpoints when the explicit question involves drought severity, drought category (D0–D4), or water stress tied to drought conditions specifically in the United States.

## Known failure modes

- Invalid or unrecognized US state/region returns 400 error
- Payment not processed or x402 header missing returns 402 Payment Required
- Drought Monitor data temporarily unavailable returns 503
- Region outside US coverage returns empty or error response
- Rate limiting may occur for excessive requests

## 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 a structured breakdown of drought categories (D0–D4) by percentage of area affected, a 12-week historical trend showing how drought severity has evolved, and qualitative/quantitative assessments of agricultural and municipal water impacts for the requested region.
