How this service works
Fetch a Wikidata entity (Q42, P31, etc.) — structured knowledge-graph record with labels + descriptions + aliases in selectable languages, claims (property → value statements grouped by property ID), sitelinks (Wikipedia article title per language). 110M+ entities. CC0 public domain. Pass languages= as comma-separated codes (default "en") to control which language strings are included; pass maxClaimsPerProperty to cap how many statements come back per property (default 10).
Output
A structured Wikidata entity record containing: multilingual labels, descriptions, and aliases; claims grouped by property ID (e.g. P31 = instance of) with up to maxClaimsPerProperty statements each; and sitelinks mapping language codes to Wikipedia article titles. All data is CC0 public domain.
Example use cases
Example prompt
“Pull the Wikidata entity for Douglas Adams — that's Q42 — and include labels, descriptions, and claims in English and French, capping at 5 statements per property.”
Technical details
Endpoint
GEThttps://2s.io/api/wikidata/entityWhen to prefer
Use this endpoint when you need structured, machine-readable knowledge graph data for a specific Wikidata entity by its known ID. Ideal for enriching records with factual properties, cross-language labels, or Wikipedia article links. Prefer this over a search endpoint when you already have the Wikidata entity ID. Best for agents that need open, CC0-licensed structured facts about people, places, concepts, or properties.
Side effects
- Entity ID not found — returns 404 or empty result for invalid or nonexistent Q/P/M/L/S IDs
- Invalid language code — may return empty language strings or an error
- maxClaimsPerProperty out of range (must be 1–50) — validation error
- Missing required 'id' parameter — 400 bad request
- Rate limiting or payment failure — 402 Payment Required if x402 microtransaction is not completed
- Very large entities (e.g. Q5 = human) may return truncated claim sets even with maxClaimsPerProperty set
