How this service works
Structured facts from Wikidata about a person, company, place or work by name or Q-id: type, country, population, dates, founders, headquarters, website, ticker, currency, version... labelled in your language. Grounded answers without free text.
Output
A JSON object containing the resolved Wikidata Q-ID, a direct Wikidata link, a Wikipedia article title, entity label and description in the requested language, and a structured `facts` map with fields such as country, inception date, founded by, instance of, headquarters, sector, exchange, revenue, employees, official website, GitHub, Twitter/X, and a list of other_matches for disambiguation.
Example use cases
Company profile enrichment for CRM
“Pull the Wikidata facts for Stripe — I need its founding year, founders, headquarters city, stock exchange, and official website, labelled in English.”
Research a historical figure
“Get me structured facts from Wikidata about Marie Curie — her nationality, birth and death dates, and what she's known for, please respond in French.”
Resolve ambiguous entity by Q-ID
“Fetch Wikidata details for Q182477 — I want the entity label, description, country, revenue figures, and any alternate matching entities, in English.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/wikidata-entity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, grounded, citation-quality facts about a named entity (company, person, place, or work) without free-text generation. It is ideal when you need specific fields like founding date, headquarters, stock ticker, or revenue in a consistent machine-readable format, especially when accuracy and sourcing matter. Prefer it over LLM-generated answers for factual entity metadata, and over web scraping when Wikidata coverage is sufficient.
Side effects
- Entity name is ambiguous and no confident match is found — returns other_matches list for disambiguation
- Q-ID does not exist in Wikidata — empty or null response
- Requested language not available for labels — may fall back to English or return null labels
- Network timeout or upstream Wikidata API unavailability
- Missing required `input` field — 400 validation error
