## 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 vibes-coded-wikipedia-summary-api-20d9fcf1 -d '<json body>'
```

Example prompt: Can you pull the Wikipedia summary for 'HTTP 402 Payment Required' and give me the extract and page URL?

## When to prefer this

Choose this endpoint when you need a quick, factual, encyclopedia-level summary of a well-known topic and want a structured JSON response including the Wikipedia URL. Prefer it over a full web scrape when a concise extract is sufficient and you want a deterministic, pay-per-call model with no subscription. Best for enriching agent responses, grounding factual claims, or adding reference links to content — especially when integrated into an x402 micropayment-enabled agent workflow.

## Known failure modes

- Topic not found on Wikipedia — returns ok:false or empty extract
- Ambiguous search term matches wrong article — returns summary for unintended topic
- Wikipedia API unavailable or rate-limited — may return error or timeout
- Payment failure (HTTP 402) if USDC payment not properly attached
- Misspelled or highly obscure topic returns no result
