## 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 wri-aqueduct-4-0-country-water-risk-indicators-f20d225e
```

Example prompt: What are Turkey's WRI Aqueduct 4.0 water stress and water depletion scores, including their category labels and global country rankings? Use the ISO code TUR.

## When to prefer this

Choose this endpoint when you need standardized, WRI Aqueduct 4.0 country-level water risk scores with categorical labels and global rankings — especially for ESG reporting, supply chain risk assessment, or investment due diligence requiring authoritative, citable water stress data at the national level. It is not suitable for sub-national, basin-level, or real-time water measurement data.

## Known failure modes

- Invalid or unrecognized ISO alpha-3 country code returns an error or empty indicators array
- Countries not covered by WRI Aqueduct 4.0 country baseline may return partial or no indicator data
- Sub-national or basin-level data is not available — only national aggregates are returned
- Network or upstream Resource Watch API unavailability may cause timeouts or 5xx errors

## How this service works

WRI Aqueduct 4.0 country water-risk indicators (default weighting): baseline water stress, baseline water depletion, interannual and seasonal variability and drought risk where published, each with score (0-5), category label and country rank, from the Aqueduct 4.0 country baseline on Resource Watch. Sub-national (basin) values are not included.

## Output

A JSON object containing the country name, ISO code, data source URL, retrieval timestamp, weighting scheme, and an array of water-risk indicators — each with a short code (e.g. 'bws', 'bwd'), full name, numeric score (0–5), category integer, human-readable label (e.g. 'High (40–80%)'), and global country rank. Also includes WRI Aqueduct 4.0 attribution.
