## 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-grassland-share-85de9cf8 -d '<json body>'
```

Example prompt: What share of the land around coordinates 52.4, -8.0 in Ireland is classified as grassland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need ESA WorldCover 2021 grassland land cover fractions specifically for points within Ireland. It is ideal for agricultural land assessment, environmental baseline reporting, subsidy eligibility checks, and ecological analysis where satellite-derived land classification at the 2021 reference year is required. Prefer it over generic GIS tools when you need a cheap, per-point, pay-per-call lookup with built-in Irish boundary validation.

## Known failure modes

- Coordinate outside Ireland boundary – rejected before payment with a validation error
- Latitude or longitude outside the European coverage range (lat 34–72.5, lon -31.5–40.5) – schema validation failure
- Malformed request body – missing required latitude or longitude fields
- Service unavailable or upstream ESA data layer error – 5xx response

## How this service works

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

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as grassland within the analysis grid around the submitted Irish coordinate. Coordinates outside the Natural Earth boundary for Ireland are rejected before any payment is processed.
