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-lithuania-cropland-share-5d26f3ca -d '<json body>'
```

Example prompt: What share of land around latitude 55.1 and longitude 23.9 in Lithuania is classified as cropland according to ESA WorldCover 2021?

## When to prefer this

Choose this endpoint when you need point-level cropland land-cover fractions specifically within Lithuania, derived from the authoritative ESA WorldCover 2021 satellite dataset. It is preferable over general land-use databases when you need pixel-level precision from a recent global remote sensing product. The built-in boundary validation against Lithuania's Natural Earth geometry ensures results are always geographically valid without additional client-side checks.

## Known failure modes

- Coordinate outside Lithuania'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
- Malformed or missing coordinate fields — input schema validation error
- Payment failure via x402 protocol — transaction not completed

## How this service works

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

## Output

A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels within the analysis area around the given coordinate that are classified as cropland, restricted to validated points within Lithuania's Natural Earth boundary.
