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-ireland-tree-cover-share-82135992 -d '<json body>'
```

Example prompt: What share of the land around latitude 52.5 and longitude -8.2 in Ireland is classified as tree cover according to ESA WorldCover 2021?

## When to prefer this

Use this endpoint when you need authoritative ESA WorldCover 2021 tree cover data specifically for a coordinate within Ireland. It is preferable when you need a validated, Ireland-bounded lookup with pay-per-call pricing and no subscription. It is not suitable for non-Irish European locations (use sibling endpoints for other countries), or for other land cover types such as built-up area (use the built-up share sibling endpoint).

## Known failure modes

- Coordinates outside Ireland's Natural Earth boundary are rejected before payment is processed
- Coordinates within the broad European coverage bbox but outside Ireland are rejected
- Invalid or missing latitude/longitude fields return a validation error
- Coordinates at the boundary edge may be ambiguously rejected depending on Natural Earth polygon precision

## How this service works

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

## Output

A numeric value representing the fraction (or percentage share) of ESA WorldCover 2021 pixels at the queried coordinate that are classified as tree cover, constrained to validated coordinates within the Republic of Ireland boundary per Natural Earth.
