How this service works
Same-as links for a Wikidata entity: VIAF, ISNI, GND, Library of Congress, GeoNames, Wikipedia editions, exact-match URLs.
Output
A structured object containing the Wikidata Q-id, label, description, resolved-via info, an array of external identifiers (each with name, property, value, and URL), Wikipedia links (English URL, title, number of editions, Commons category), exact-match URLs, and metadata like attribution and disclaimer.
Example use cases
Author authority record cross-reference
“I need the VIAF, ISNI, and Library of Congress identifiers for Shakespeare — can you pull his same-as links from Wikidata?”
Place identifier lookup for data enrichment
“I'm enriching a dataset and need the GeoNames ID and any exact-match URLs for Berlin — can you get its Wikidata same-as links using Q64?”
Musician identity resolution
“Can you find all the authority file identifiers for David Bowie, like his VIAF and GND numbers, using his Wikidata entry?”
Technical details
Endpoint
GEThttps://wikidata-facts.x402tookit.com/same-as?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to resolve a Wikidata entity to its authority control identifiers (VIAF, ISNI, GND, LoC, GeoNames) or cross-reference it across linked-data systems. Ideal for library/archival workflows, knowledge graph enrichment, and any scenario where you need to confirm the same entity across multiple authoritative databases. Prefer over general Wikidata fact endpoints when your primary goal is identity linking rather than descriptive facts.
Side effects
- Unknown or ambiguous name with no unique Wikidata match — returns alternatives list for disambiguation
- Invalid Q-id format — may return null or error
- Entity exists but has no same-as/external identifier statements — identifiers array is empty
- Network timeout or Wikidata API unavailability — degraded flag set to true
- Name hint insufficient to resolve ambiguity — multiple candidates returned
