# WaterPulse Aquifer Analysis

> WaterPulse Aquifer Analysis 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 depletion rates, recharge capacity, agricultural dependency, regulatory outlook, and sustainability metrics for 30+ US aquifer systems including Ogallala, Central Valley, and Floridan.

## Facts

- Endpoint: GET https://waterpulse-henna.vercel.app/api/water/aquifer
- 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-aquifer-analysis-6eb82a38
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_nF2xLuwVe-mJgl6kGSVVz

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-aquifer-analysis-6eb82a38
```

Example prompt: Can you pull the aquifer analysis for the Ogallala system — I want to see its current depletion rate, recharge capacity, agricultural dependency, and whether its regulatory and sustainability outlook is still investable?

## When to prefer this

Use this endpoint when you need detailed groundwater sustainability intelligence on specific US aquifer systems, particularly for investment risk analysis, agricultural water planning, or regulatory compliance research. Prefer this over general water stress or drought endpoints when aquifer-specific depletion, recharge, and sustainability metrics are required rather than surface water or reservoir data.

## Known failure modes

- Unsupported or unrecognized aquifer name returns error or empty result
- Aquifer not in the 30+ supported systems returns no data
- Network or service unavailability returns HTTP error
- Malformed request parameters result in 400 error
- Payment not processed results in 402 error

## 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 for the specified US aquifer including depletion rate trends, recharge capacity, agricultural dependency percentage, regulatory environment summary, and an overall sustainability assessment covering 30+ major US aquifer systems.
