# HALOWERK Europe Land – Cropland Share (1000m Buffer)

> HALOWERK Europe Land – Cropland Share (1000m Buffer) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).

Returns the share of ESA WorldCover 2021 pixels classified as cropland within a 1,000-metre circular buffer around a given European coordinate.

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-europe-land-cropland-share-1000m-buffer-e8382511 -d '<json body>'
```

Example prompt: What share of land within a 1,000-metre radius of latitude 48.85, longitude 2.35 is classified as cropland according to ESA WorldCover?

## When to prefer this

Use this endpoint when you need a medium-scale (1km neighborhood) cropland land-cover fraction for a specific point in Europe, derived from standardized ESA WorldCover 2021 satellite data. Prefer this over the 250m buffer variant when broader neighborhood context matters more than hyper-local conditions, and over polygon-based endpoints when you only have a point coordinate rather than a bounded area.

## Known failure modes

- Coordinates outside the European coverage bbox (lat 34–72.5, lon -31.5–40.5) return a validation error
- Missing latitude or longitude fields result in a 400 bad request
- Network or service unavailability returns a 5xx error
- Coordinates within coverage but over the ocean may return zero or near-zero cropland share legitimately

## How this service works

Share of ESA WorldCover 2021 pixels classified as cropland. The service evaluates a circular 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021-classified cropland pixels within a circular 1,000-metre neighborhood around the supplied coordinate, standardized across the 30 covered European countries.
