## 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 amnt-encyclopaedia-summary-194381df -d '<json body>'
```

Example prompt: Can you give me the Wikipedia summary for 'Photosynthesis' — just the plain-English lead extract with any key metadata?

## When to prefer this

Choose this endpoint when you need a quick, authoritative, plain-English summary of a well-known topic, person, place, or concept and want to avoid scraping Wikipedia yourself. It is ideal for agents that need factual background context on demand without managing browser sessions or accounts. Prefer it over generic web-search endpoints when a structured encyclopedia extract (lead paragraph + metadata) is specifically what's needed.

## Known failure modes

- Article title not found on Wikipedia — returns an error or empty result
- Ambiguous title resolving to wrong article — extract may not match intent
- Wikipedia API downtime — service unavailable response
- Malformed prompt input — missing required 'prompt' field returns validation error
- x402 payment failure — call does not proceed if payment cannot be settled

## How this service works

Encyclopaedia Summary - Concise, plain-English encyclopaedia summaries from Wikipedia: supply an article title and get the lead extract and metadata.. Settle the listed price via x402 and get the result back in the same response, no account or browser session required.

## Output

The agent receives the lead extract (introduction section) of the specified Wikipedia article in plain text, along with article metadata such as the canonical title and page identifiers. The response is returned directly in the same HTTP response after the x402 payment is settled.
