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 halowerk-atlantic-land-ireland-built-up-share-35943619 -d '<json body>'
```

Example prompt: What share of ESA WorldCover 2021 pixels are classified as built-up at latitude 53.3498, longitude -6.2603 in Ireland?

## When to prefer this

Choose this endpoint when you need a precise, satellite-derived built-up land cover fraction specifically for a point in Ireland, sourced from the authoritative ESA WorldCover 2021 dataset. It is ideal for real estate analysis, urban planning, environmental assessments, or any workflow requiring quantified urbanization levels at a GPS coordinate within Ireland. Prefer it over generic land-use APIs when you need Ireland-specific boundary validation and WorldCover 2021 classification accuracy.

## Known failure modes

- Coordinate outside Ireland boundary — request rejected before payment is charged
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed coordinate values (non-numeric, missing fields) — schema validation error
- Payment failure via x402 protocol — request not processed

## How this service works

Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Ireland; results outside it are rejected before payment.

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as built-up within the analysis grid around the submitted coordinate. Returns a rejection if the coordinate falls outside Ireland's Natural Earth boundary.
