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's plain-text summary, structured Wikidata fields (official website, founding/establishment date, birth date, death date, population, geographic coordinates), and a direct source URL to the Wikipedia article. Supports any language edition via the lang parameter.
Example use cases
Grounding AI responses with verified facts
“Before answering questions about OpenAI, pull up the Wikipedia summary and key Wikidata facts — founding date, website, and headquarters coordinates — so your answer is grounded in real data.”
City population and location lookup
“What's the current population of Tokyo and what are its geographic coordinates? Pull from Wikipedia and Wikidata.”
Historical figure biography lookup
“Look up Albert Einstein on Wikipedia and give me a short summary plus his birth date, death date, and any official links.”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/facts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to ground its responses in verified encyclopedic facts about a person, place, organization, or concept — especially when structured fields like coordinates, population, or founding dates are needed alongside a readable summary. Prefer it over a general web search when you want reliable, structured Wikidata properties rather than unstructured web content. Ideal for fact-checking, entity enrichment, and knowledge grounding tasks. Supports multilingual queries, making it suitable for non-English contexts.
Side effects
- No matching Wikipedia article found for the query — returns empty or null result
- Ambiguous query matches a disambiguation page rather than a specific entity
- Wikidata entry exists but lacks certain structured fields (e.g. no founding date), returning partial data
- Unsupported or invalid language code returns error or falls back to English
- Rate limiting or payment failure returns HTTP 402 or 429
