# HALOWERK Atlantic Land – Ireland Surface Elevation

> HALOWERK Atlantic Land – Ireland Surface Elevation is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Returns bilinear-interpolated surface elevation in metres for a given WGS84 coordinate within Ireland, sourced from Copernicus DEM GLO-30.

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-surface-elevation-35bf9e06 -d '<json body>'
```

Example prompt: What is the surface elevation in metres at latitude 53.3498, longitude -6.2603 in Ireland, using the Copernicus GLO-30 DEM?

## When to prefer this

Choose this endpoint when you need high-resolution (GLO-30, ~30m) terrain elevation specifically for locations within Ireland, with automatic boundary validation ensuring you only pay for valid Irish coordinates. Prefer this over generic global DEM APIs when Ireland-specific validation and Copernicus-sourced accuracy are required.

## Known failure modes

- Coordinate outside Ireland Natural Earth boundary — rejected before payment with a boundary validation error
- Latitude or longitude outside the European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing coordinate fields — input validation error
- Service unavailable or DEM data inaccessible — upstream provider error

## How this service works

Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Ireland; results outside it are rejected before payment.

## Output

Returns the bilinear-interpolated surface elevation in metres above sea level for the queried coordinate, derived from the Copernicus DEM GLO-30 dataset, with coordinate validation confirming the point falls within the Ireland boundary before any charge is applied.
