How this service works
Facts for one Wikidata entity: label, description, aliases, instance-of, Wikipedia links and key identifiers.
Output
A structured object containing the entity's Wikidata Q-id, human-readable label, description, list of aliases, instance-of array (with Q-ids and labels), Wikipedia link (English title and URL, plus edition count), and an array of external identifiers (name, property, value, and URL). Also includes statement count, last-modified date, resolution method, and attribution.
Example use cases
Entity type classification from name
“I have the name 'Marie Curie' — can you pull her Wikidata entry and tell me her Q-id, description, instance-of classification, and any known aliases?”
Enriching a dataset with Wikidata metadata
“I have a list item identified as Q76 — fetch its Wikidata label, description, Wikipedia link, and key external identifiers so I can enrich my database record.”
Disambiguating an ambiguous concept
“Look up 'Paris' on Wikidata with the hint 'capital of France' and return its label, description, aliases, instance-of, and Wikipedia URL.”
Technical details
Endpoint
GEThttps://wikidata-facts.x402tookit.com/entity-facts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured fact-sheet for a single known entity (by Q-id or unambiguous name) and want label, description, aliases, instance-of, Wikipedia links, and external identifiers in one call. Prefer it over a full Wikidata SPARQL query when you don't need deep property traversal. Use the sibling search endpoint first if you only have an ambiguous name and need to resolve it to a Q-id.
Side effects
- Unknown or malformed Q-id returns null or empty result
- Ambiguous name with no hint may resolve to the wrong entity or return alternatives list
- Entity exists but has no English label — label field may be null
- Rate limiting or payment failure returns 402 or 429 status
- Entity with very few statements may return sparse data with many null fields
