## 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 saylor-innovations-wikipedia-nearby-places-cb48c64d
```

Example prompt: What Wikipedia places are within 800 metres of latitude 51.5074, longitude -0.1278? Show me up to 15 results sorted by distance.

## When to prefer this

Use this endpoint when you need geospatially-ranked Wikipedia content about places near a coordinate — ideal for enriching location data with encyclopedic context, building travel guides, populating map overlays, or doing research on historically or culturally significant sites near a known GPS point. Prefer this over a general web search when you need structured, distance-ordered results with Wikidata IDs for knowledge graph linking.

## Known failure modes

- Missing required lat or lon parameters returns an error
- Out-of-range coordinates (lat outside -90 to 90, lon outside -180 to 180) may return an error or empty results
- Radius outside 10–10000 metre range may be clamped or rejected
- Limit outside 1–25 range may be clamped or return an error
- Remote or unpopulated coordinates may return zero results if no Wikipedia articles exist nearby
- Payment failure (x402) if USDC not provided correctly

## How this service works

Wikipedia articles near a coordinate within a radius - title, short description, summary, distance in metres, position and Wikidata id, nearest first

## Output

A JSON object containing the query center coordinates, search radius in metres, total count of results, and an array of nearby Wikipedia articles each with: title, short description, longer summary, latitude, longitude, distance in metres, canonical Wikipedia URL, and Wikidata entity ID (nullable). Results are sorted nearest-first.
