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 a JSON object containing the best-matching Wikipedia article summary (a few paragraphs), structured Wikidata fields (website, founding date, birth date, death date, population, geographic coordinates), and a source link to the Wikipedia article. Any Wikipedia language edition is supported.
Example use cases
Grounding agent output with verified facts
“Before you finalize that company profile, look up Tesla Inc. and pull its founding date, official website, and a short Wikipedia summary to make sure everything checks out.”
Researching a historical figure
“Tell me about Napoleon Bonaparte — when he was born and died, and give me a Wikipedia summary of his life.”
Getting population and coordinates for a city
“I need the population and geographic coordinates for Tokyo, along with a brief Wikipedia description — can you look that up?”

Endpoint
GEThttps://agentrxi.com/v1/facts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need reliable, encyclopedic factual grounding about well-known entities — people, places, organizations, or concepts — especially when structured fields like founding dates, population, coordinates, or birth/death dates are needed alongside a narrative summary. Prefer it over general web search when you want structured Wikidata fields in addition to prose, or when you need multilingual Wikipedia coverage.
Side effects
- No matching Wikipedia article found for the query — returns empty or null result
- Ambiguous query resolves to an unexpected article — agent should refine the query
- Wikidata fields may be partially missing if the entity lacks structured data
- Unsupported or invalid language code returns an error or falls back to English
- Rate limiting or payment failure returns a 402 or 429 error
