# HALOWERK Atlantic Land – Ireland Aspect Direction

> HALOWERK Atlantic Land – Ireland Aspect Direction is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-16).

Returns the circular direction (in degrees, clockwise from north) of the dominant surface slope gradient for a given coordinate within Ireland.

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-aspect-direction-356410e9 -d '<json body>'
```

Example prompt: What direction does the hillside face at latitude 52.1 and longitude -8.5 in Ireland — clockwise from north?

## When to prefer this

Use this endpoint when you need the compass direction of the dominant surface slope at a specific location within Ireland. It is ideal for land suitability analysis, drainage planning, solar exposure assessments, and ecological habitat studies where slope orientation is a key variable. Prefer this over generic elevation APIs when you specifically need aspect (direction) rather than slope magnitude, and when your coordinates are within Ireland.

## Known failure modes

- Coordinate outside Ireland boundary: rejected before payment, returns boundary violation error
- Coordinate within European bounding box but outside Ireland polygon: rejected with geographic validation error
- Missing latitude or longitude parameter: returns validation error
- Latitude or longitude outside European bounding box (34–72.5°N, -31.5–40.5°E): schema validation failure
- Flat terrain with near-zero gradient: may return undefined or null aspect value

## How this service works

Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Ireland; results outside it are rejected before payment.

## Output

Returns the circular aspect angle in degrees (0–360, clockwise from north) representing the dominant direction of the surface gradient at the queried coordinate. Coordinates outside the Natural Earth boundary for Ireland are rejected before any payment is charged.
