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-eastern-land-romania-cropland-share-4f4353b9 -d '<json body>'
```

Example prompt: What's the ESA WorldCover cropland share at latitude 44.8, longitude 26.5 in Romania — I need to know what fraction of the land there is classified as cropland.

## When to prefer this

Choose this endpoint when you need a precise, point-based cropland coverage fraction for a specific Romanian coordinate derived from ESA WorldCover 2021. It is ideal for agricultural analysis, land suitability assessments, or geospatial enrichment pipelines focused on Romania. Prefer this over generic GIS APIs when you need a ready-to-consume scalar metric without raw raster data handling, and when Romania-specific boundary validation is desirable as a built-in safeguard.

## Known failure modes

- Coordinate outside Romania boundary — request is 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
- Missing or malformed latitude/longitude fields — schema validation error
- Payment failure — USDC transaction not completed
- Service unavailable — upstream data source temporarily unreachable

## How this service works

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

## Output

A numeric value representing the fraction (share) of ESA WorldCover 2021 pixels at or around the given coordinate that are classified as cropland. The coordinate is validated against Romania's Natural Earth boundary; requests outside Romania are rejected.
