# ChainVerdict EUDR Geo-Check

> ChainVerdict EUDR Geo-Check is a paid API for AI agents from reg.chainverdict.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-16).

Validates EUDR plot geolocation by checking coordinate bounds, ring closure, self-intersection, area, size-to-geometry rules, and lat/lon axis ordering errors.

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 chainverdict-eudr-geo-check-1025258b -d '<json body>'
```

Example prompt: Can you check this EUDR plot geometry for me — it's a polygon with coordinates [[[12.34, 1.23], [12.35, 1.23], [12.35, 1.24], [12.34, 1.24], [12.34, 1.23]]] — make sure the ring is closed, there's no self-intersection, the area is right, and the axes aren't swapped?

## When to prefer this

Use this endpoint when you need to validate plot geolocation data specifically for EUDR compliance before submitting a Due Diligence Statement. It is uniquely valuable for catching the silent lat/lon axis-swap error that relocates a plot to the wrong continent, and for enforcing the EUDR rule that plots above 4 hectares must use polygon geometry rather than a point. Prefer this over generic GeoJSON validators when EUDR-specific rules (area threshold, commodity traceability context) matter.

## Known failure modes

- Malformed GeoJSON or missing geometry fields returns a parsing error
- Coordinates outside valid WGS84 bounds (-90 to 90 lat, -180 to 180 lon) flagged as invalid
- Point geometry submitted for plot exceeding 4 hectares triggers a rule violation
- Self-intersecting polygon detected and flagged with intersection location
- Unclosed ring detected when first and last coordinate pair do not match
- Suspected lat/lon swap reported when coordinates place the plot implausibly (e.g. ocean or wrong continent)

## How this service works

Validate EUDR plot geolocation: coordinate bounds, ring closure, self-intersection, approximate area, and the rule that plots above 4 hectares require a polygon rather than a point. Catches the [lat, lon] versus [lon, lat] error that silently relocates a plot to the wrong continent.

## Output

Returns a structured validation result indicating whether the plot geometry passes EUDR geo requirements, with specific flags for: coordinate out-of-bounds errors, unclosed rings, self-intersections, approximate computed area in hectares, whether the geometry type (point vs polygon) satisfies the 4-hectare size rule, and whether a lat/lon axis swap is suspected based on coordinate plausibility.
