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-luxembourg-cropland-share-c0ec04fc -d '<json body>'
```

Example prompt: What share of the land around latitude 49.6116, longitude 6.1319 in Luxembourg is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need precise, pixel-level cropland fraction data derived from ESA WorldCover 2021 for a specific point within Luxembourg. It is ideal for agricultural land assessment, investment due diligence, environmental impact analysis, or land use monitoring within Luxembourg boundaries. Prefer it over general GIS APIs when you need a pay-per-query, low-cost lookup with built-in boundary validation.

## Known failure modes

- Coordinate outside Luxembourg boundary — rejected with validation error before payment
- Latitude or longitude outside allowed European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Non-cropland location returns a share of 0 or near-zero, which is valid but may surprise users expecting agricultural data
- Network or upstream data service unavailability — HTTP 5xx error

## How this service works

Share of ESA WorldCover 2021 pixels classified as cropland. The coordinate is validated against the Natural Earth boundary for Luxembourg; results outside it are rejected before payment.

## Output

A numeric share (fraction or percentage) indicating what proportion of ESA WorldCover 2021 pixels in the analysis grid around the given coordinate are classified as cropland. Coordinates outside the Luxembourg Natural Earth boundary are rejected before payment is processed.
