How this service works
Wikidata entity lookup: the Q-id, label, description, aliases, and key claims (instance of, country, population, inception, coordinates, official website, founder, headquarters) resolved to labels. Structured facts for grounding. $0.01 per lookup.
Output
Returns the entity's Wikidata Q-id, canonical label, short description, aliases, and a set of key claims — including instance-of, country, population, inception date, geographic coordinates, official website URL, founder, and headquarters — all resolved to human-readable labels rather than raw Q-ids.
Example use cases
Grounding entity mentions in NLP pipelines
“I have the entity 'Marie Curie' appearing in a document — can you fetch her Wikidata Q-id, description, birth date, and country so I can ground it with structured facts?”
Enriching a company database with Wikidata facts
“Pull the Wikidata entry for Toyota — I need the Q-id, country, inception year, headquarters, and official website to enrich our company records.”
Looking up city population and coordinates
“What does Wikidata say about São Paulo? I need the Q-id, population figure, coordinates, and country label for a data enrichment task.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/data/wikidataWhen to prefer
Choose this endpoint when you need structured, factual grounding data for a specific named entity — especially when you already have or can guess a Q-id, or need a consistent set of key claims (founder, population, coordinates, etc.) without parsing raw Wikidata SPARQL results yourself. Prefer it over Wikipedia search when you want machine-readable structured claims rather than prose snippets, and over full Wikidata SPARQL when you only need the standard set of common claims and want a simple REST call with per-lookup pricing.
Side effects
- Entity not found in Wikidata — returns empty or error response
- Ambiguous name with multiple matching entities — may return the wrong entity
- Claims not present for that entity — fields will be null or absent
- Payment failure — x402 micropayment not completed, request rejected
- Rate limiting or server error from the upstream Wikidata API
