## 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-southern-land-italy-grassland-share-3f16642b -d '<json body>'
```

Example prompt: What share of the land around latitude 41.9, longitude 12.5 in Italy is classified as grassland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need pixel-level grassland land cover fractions for a specific point location in Italy, sourced from the authoritative ESA WorldCover 2021 dataset. It is ideal for site-specific environmental assessments, agricultural land analysis, habitat monitoring, or any geospatial workflow requiring validated land cover data within Italy. Prefer it over generic land cover APIs when you need Italy-validated coordinates and WorldCover 2021 classification specifically.

## Known failure modes

- Coordinate outside Italy's Natural Earth boundary — request rejected before payment is processed
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate values — schema validation failure
- Service unavailability or timeout — HTTP 5xx error

## How this service works

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

## Output

A numeric share (fraction or percentage) representing how much of the ESA WorldCover 2021 analysis area around the given coordinate is classified as grassland, restricted to valid coordinates within Italy's Natural Earth boundary.
