## How to call it through Zero

```

Example prompt: Look up Wikipedia facts about Elon Musk — I want his birth date, any official website listed, and a short summary of who he is.

## When to prefer this

Choose this endpoint when you need fast, encyclopedic fact grounding for a person, place, organization, or concept — especially when you need structured data fields like founding date, coordinates, or population alongside a readable summary. Prefer it over web scraping when Wikipedia/Wikidata coverage is sufficient and you want clean, structured output without parsing HTML. Ideal for RAG pipelines, agent fact-grounding steps, or enriching entity records with canonical knowledge-graph data.

## Known failure modes

- No matching Wikipedia article found for the query — returns empty or low-confidence result
- Ambiguous query matches wrong article — summary and facts may refer to an unintended subject
- Wikidata fields partially populated — some structured facts (e.g. population or coordinates) may be absent if not in Wikidata
- Non-existent language edition requested — falls back or errors if the specified language Wikipedia lacks the article
- Rate limiting or payment failure — HTTP 402 if payment not processed correctly

## How this service works

Fact lookup for grounding: best-matching Wikipedia article summary plus structured Wikidata facts (website, founding date, birth/death dates, population, coordinates) and the source link. Any language edition.

## Output

Returns the best-matching Wikipedia article summary as a text excerpt, structured Wikidata facts (website, founding date, birth/death dates, population, latitude/longitude coordinates), and a source link to the Wikipedia page. Supports any Wikipedia language edition via a language code parameter.
