# WaterPulse Supply Snapshot

> WaterPulse Supply Snapshot is a paid API for AI agents from waterpulse.theaslangroupllc.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Returns a combined drought and groundwater depth snapshot for a given US location, pulling from USGS and US Drought Monitor sources.

## Facts

- Endpoint: GET https://waterpulse.theaslangroupllc.com/api/water/supply-snapshot
- Price: $0.25/call
- Payment: x402

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-snapshot-fca464e8
```

Example prompt: Pull up the current water supply snapshot for Phoenix, AZ — I want to see the drought severity breakdown and how deep the groundwater is at nearby wells as of today.

## When to prefer this

Choose this endpoint when you need a fast, combined view of drought severity and groundwater depth for a specific US location without needing full infrastructure, reservoir, or rate trajectory data. It is the lightweight entry point (at $0.25) compared to the richer /api/water/supply-brief ($0.50). Prefer this for quick environmental checks, risk screening, or monitoring workflows where summary-level drought and well data is sufficient.

## Known failure modes

- Location not found or ambiguous — returns error if the state/city cannot be resolved to a monitoring region
- No wells reporting — groundwater_snapshot may return empty readings array if no USGS wells are active in the area
- Drought Monitor data lag — drought_snapshot as_of date may be several days behind current date due to weekly update cadence
- Invalid or missing required parameters — returns 400-style error if state or location is not provided
- Payment failure — x402 payment of $0.25 USDC required; unpaid requests return 402

## How this service works

Deterministic water-supply numbers snapshot for a US state — latest USGS groundwater well readings (depth-to-water) and current US Drought Monitor D0-D4 breakdown. No LLM, no web search. The $0.50 /api/water/supply-brief adds reservoir storage, utility outlook, restrictions, rate trajectory, and a synthesized 5-year risk rating.

## Output

Returns a JSON object with: a drought_snapshot showing percentages of the queried area in each drought category (D0–D4, none, in_drought), a groundwater_snapshot listing individual well readings (site name, code, depth to water in feet, datetime) plus aggregate stats (avg/min/max depth, number of wells reporting), and a query_summary confirming the state, location, and report date. Also includes an upsell pointer to a richer /api/water/supply-brief endpoint.
