## 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 dt0ur-online-wikipedia-semantic-search-9a4e02bc -d '<json body>'
```

Example prompt: Can you search Wikipedia for 'quantum entanglement' and give me a quick summary with the canonical article URL I can cite?

## When to prefer this

Choose this endpoint when an AI agent needs fast encyclopedic context, fact grounding, or canonical reference URLs from Wikipedia without building a direct Wikipedia API integration. Particularly useful when caching is acceptable to reduce latency and cost, or when force_live=true is needed for freshness. Prefer over raw Wikipedia API when you need snippet extraction and canonical URLs bundled in a single paid call with predictable pricing.

## Known failure modes

- Query returns no matching Wikipedia articles — empty results set returned
- Upstream Wikipedia API unavailable when force_live=true — upstream timeout or error response
- Malformed or empty query string — validation error returned
- Cache miss with live fetch failure — partial or error response
- Rate limiting or payment failure at x402 layer — 402 Payment Required response

## How this service works
