## How to call it through Zero

```

Example prompt: Can you pull up the Wikipedia summary for Marie Curie — just the lead extract that explains who she was and what she's known for?

## When to prefer this

Use this endpoint when you need a concise, encyclopedic overview of a well-known topic, entity, person, place, or concept — especially when you want the authoritative crowd-sourced summary rather than web search snippets. Prefer it over general web search when you specifically want Wikipedia's structured lead extract, or when enriching data records with background descriptions.

## Known failure modes

- Ambiguous title results in wrong article being returned
- Very obscure topics may have no Wikipedia page, returning a not-found error
- Recently created or deleted Wikipedia pages may not be available
- Non-English or alternate language titles may not resolve correctly
