## 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 naturepedia-geology-registry-a5904a2b
```

Example prompt: Pull the Naturepedia Geology Registry — I need the full canonical list of geology entities, rock and mineral classifications, and all ten Geology Plates in machine-readable JSON-LD format.

## When to prefer this

Choose this endpoint when you need a canonical, deduplicated, machine-readable registry of geology entities and classifications in JSON-LD format — specifically when you want structured Naturepedia Geology Plate data for knowledge graph ingestion, ontology mapping, or geoscience taxonomy enrichment. Prefer this over general web search or unstructured geology data sources when you need entity-resolved, schema-conformant geology data ready for agent consumption.

## Known failure modes

- Missing or invalid 'resource' query parameter returns an error response
- Incorrect resource URL format causes lookup failure
- Payment not completed (x402 protocol) results in 402 Payment Required response
- Network timeout if service is temporarily unavailable
- Resource URL pointing to non-geology registry returns wrong or empty data

## How this service works

Canonical machine-readable registry of Geology™ entities, classifications, and ten Naturepedia Plates.

## Output

A JSON-LD object containing a @context, @type, name, description, and an array of geological systems entries representing canonically resolved geology entities, rock/mineral classifications, and ten Naturepedia Geology Plates; also includes canonicalKeepCount and duplicateRemovedCount metadata fields indicating deduplication stats.
