## 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-netherlands-cropland-share-e63bc620 -d '<json body>'
```

Example prompt: What share of the land around latitude 52.1 and longitude 5.1 in the Netherlands is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need a precise, point-based cropland fraction derived from ESA WorldCover 2021 specifically for a coordinate within the Netherlands. It is ideal for agricultural land assessment, environmental reporting, site suitability analysis, or any workflow requiring validated, boundary-checked land cover data for Dutch locations. Prefer this over generic GIS APIs when you need a pay-per-call, low-latency lookup with built-in boundary validation for the Netherlands.

## Known failure modes

- Coordinate outside Netherlands boundary: request rejected before payment, likely returns a 4xx error with boundary validation message
- Coordinate outside European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Malformed or missing latitude/longitude: input validation error
- Coordinate on edge cases (coastline, border): may be rejected by Natural Earth boundary check
- Service unavailability or upstream ESA data issue: 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 Netherlands; results outside it are rejected before payment.

## Output

A numeric share (fraction or percentage) of ESA WorldCover 2021 pixels classified as cropland within the analysis grid surrounding the provided coordinate in the Netherlands. The coordinate is validated against the Natural Earth boundary for the Netherlands; requests outside this boundary are rejected before any payment is processed.
