# HALOWERK Atlantic Land – Ireland Local Relief

> HALOWERK Atlantic Land – Ireland Local Relief 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 the local relief index (max minus min sampled surface elevation) for a coordinate within Ireland, validated against the Natural Earth Ireland boundary.

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-local-relief-d8beb666 -d '<json body>'
```

Example prompt: What's the local relief — the difference between the highest and lowest sampled surface elevation — at latitude 51.9 and longitude -8.5 in Ireland?

## When to prefer this

Choose this endpoint when you specifically need local relief (elevation range) for a point in Ireland. It is purpose-built for Irish coordinates with boundary validation baked in, making it more reliable than generic global elevation APIs for Irish land analysis. Prefer it for terrain ruggedness screening, land suitability studies, or any Irish geospatial workflow needing a concise elevation variability metric.

## Known failure modes

- Coordinate outside Ireland boundary — rejected before payment with a validation error
- Coordinate within European coverage bounds but outside Ireland — rejected by Natural Earth boundary check
- Missing or malformed latitude/longitude — schema validation error
- Coordinate at the edge of available DEM coverage — potential data gap error

## How this service works

Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Ireland; results outside it are rejected before payment.

## Output

A single numeric value representing the local relief in metres — the difference between the maximum and minimum sampled surface elevations within the analysis grid centred on the requested coordinate. Coordinates outside Ireland are rejected before processing.
