## 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 signaldesk-ai-wikipedia-summary-130a7def
```

Example prompt: Pull up the Wikipedia summary for 'Rust_(programming_language)' so I can get a quick overview of what it is.

## When to prefer this

Choose this endpoint when you need a quick, structured Wikipedia summary for a known article title and want a paid, reliable micro-service wrapper with a consistent JSON schema. Prefer it over raw Wikipedia API calls when operating within an x402 payment-enabled agent pipeline that already handles micropayments, or when you need a stable, schema-validated response format with bounded execution guarantees.

## Known failure modes

- Article title not found or misspelled — returns error or empty result
- Ambiguous title with no exact match — may return wrong article
- Rate limiting or quota exhaustion on free tier — request blocked
- Wikipedia API unavailable — upstream timeout or error
- Missing required 'title' query parameter — schema validation error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the Wikipedia article's title, a text summary/excerpt, and the full Wikipedia page URL (e.g. {titulo, resumo, pagina}).
