How this service works
All values of one Wikidata property (for example P1082 population) on an entity, with ranks and dates.
Output
A structured response including the entity label, the requested property, an array of all matching values each with its rank (preferred/normal/deprecated), point-in-time date, numeric amount, and unit label; plus a 'best' value summarizing the top-ranked entry, a human-readable summary, and attribution/source metadata.
Example use cases
Historical population trend research
“Can you pull all the population values (P1082) that Wikidata has for New York City (Q60), including the dates each figure was recorded?”
Country capital fact-check
“What does Wikidata list as the capital (P36) of Germany? Give me all values with their ranks.”
Scientific measurement lookup
“Fetch the elevation (P2044) for Mount Everest from Wikidata — I want all recorded values and their units.”
Technical details
Endpoint
GEThttps://wikidata-facts.x402tookit.com/property-value?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, ranked, time-stamped values for a specific Wikidata property on a known entity — especially when you want historical series (e.g. multiple population records), unit metadata, or need to distinguish preferred vs deprecated values. Prefer this over a general entity profile endpoint when you only need one specific property rather than a full profile.
Side effects
- Entity not found if Q-id is invalid or name is ambiguous without a hint
- Property not found on entity returns empty values array
- Name disambiguation failure returns alternatives list instead of values
- Network or Wikidata API timeout results in degraded or partial response
- Invalid property id format returns an error
