## How to call it through Zero

```sh
zero fetch --capability molcloud-wikipedia-info-lookup-3aa185eb
```

Example prompt: Can you pull up a Wikipedia summary for Ethereum in English? I need a quick factual overview to include in a research brief.

## When to prefer this

Choose this endpoint when you need a quick, structured, factual summary of a named entity or topic sourced from Wikipedia, especially within an autonomous agent pipeline that settles payments in USDC on Base via x402. It is ideal for grounding AI responses with encyclopedia-level facts, enriching data pipelines with entity descriptions, or verifying basic information about crypto projects, protocols, or general concepts — all in a single pay-per-request call without requiring a Wikipedia API key or custom integration.

## Known failure modes

- Query term not found on Wikipedia — may return empty data object or 404-equivalent status
- Ambiguous query returns wrong article — agent should use more specific entity name
- Unsupported language code causes fallback or error
- Rate limiting or payment failure via x402 results in 402 Payment Required response
- Network timeout from edge gateway returns 5xx error

## How this service works

## Output
