How this service works
Fetch a Wikidata entity by Q-id: label, description, aliases and its claims (property → values).
Output
Returns structured metadata for the requested Wikidata entity, including the human-readable label, description, and aliases in the specified language (defaulting to English).
Example use cases
Entity resolution for named things
“I have the Wikidata ID Q7259 — can you look it up and tell me the English label and description?”
Multilingual label retrieval
“Fetch the French label and description for Wikidata entity Q183 so I can display it in my French-language app.”
Knowledge graph enrichment pipeline
“I'm building a dataset and need structured info for Wikidata entity Q1860 — get me the label, description, and aliases in English.”
Technical details
Endpoint
POSThttps://wikidata.openverbs.com/v1/entityWhen to prefer
Use this endpoint when you have a specific Wikidata QID and need to resolve it to structured, multilingual metadata (label, description, aliases). Ideal for knowledge graph enrichment, entity resolution pipelines, or any workflow that bridges internal identifiers to human-readable encyclopedic descriptions. Prefer this over a full Wikidata SPARQL query when you only need basic entity metadata for a known QID.
Side effects
- Invalid entity ID format (must match pattern Q[0-9]+ or q[0-9]+) — returns validation error
- Entity ID does not exist in Wikidata — returns not-found error
- Requested language code is unsupported or entity has no data in that language — may return empty fields
- Payment or x402 authentication failure — returns 402 Payment Required
