# HALOWERK Atlantic Land – Ireland Depression Depth

> HALOWERK Atlantic Land – Ireland Depression Depth is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns the positive elevation difference between a neighborhood mean and the center point elevation for a given coordinate within Ireland, indicating topographic depression depth.

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-depression-depth-a6463929 -d '<json body>'
```

Example prompt: What is the topographic depression depth at latitude 53.35, longitude -6.26 in Ireland? I need the positive difference between the neighborhood mean elevation and the center point elevation for that coordinate.

## When to prefer this

Use this endpoint when you specifically need a topographic depression depth metric (neighborhood mean minus center elevation) for a point within Ireland. It is ideal for land assessment, flood risk screening, drainage planning, or ecological surveys where understanding local surface concavity is important. Prefer this over generic DEM lookups when you need the computed depression index rather than raw elevation, and when your coordinate is confirmed to be within Ireland.

## Known failure modes

- Coordinate falls outside Ireland's Natural Earth boundary — request is rejected before payment
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- No elevation data available for the requested point — null or error response
- Network timeout or service unavailability

## How this service works

Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Ireland; results outside it are rejected before payment.

## Output

A numeric value representing the positive difference between the neighborhood mean surface elevation and the center point elevation at the given coordinate, indicating how much lower the center point is relative to its surroundings. Coordinates outside Ireland's Natural Earth boundary are rejected before processing.
