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-baltic-land-dominant-land-cover-class-estonia-9a3f7ec0 -d '<json body>'
```

Example prompt: What's the dominant ESA WorldCover 2021 land cover class at latitude 58.38, longitude 26.72 in Estonia?

## When to prefer this

Use this endpoint when you need a quick, low-cost land cover classification for a specific point in Estonia based on the authoritative ESA WorldCover 2021 dataset. It is ideal when you need the single dominant class rather than a full pixel-by-pixel breakdown, and when the coordinate is confirmed to be within Estonia. Prefer this over broader European or global land cover APIs when Estonia-specific boundary validation and per-call micropayment pricing ($0.003 USDC) fit your use case.

## Known failure modes

- Coordinate outside Estonia's Natural Earth boundary — request rejected with a validation error before payment
- Latitude or longitude outside the published European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- No data available for the queried location in ESA WorldCover 2021 — null or error response
- Malformed input (missing latitude or longitude) — input schema validation error

## How this service works

Dominant ESA WorldCover 2021 class in the analysis area. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.

## Output

The endpoint returns the dominant ESA WorldCover 2021 land cover class for the queried point inside Estonia. The class represents the most prevalent land cover type within the analysis area (e.g. forest, cropland, grassland, built-up, wetland, bare/sparse vegetation, water). Coordinates outside Estonia's Natural Earth boundary are rejected before any payment is charged.
