Open Search – Wikidata Entity Resolver

Choose this endpoint when you need structured Wikidata entity resolution — specifically Q-ids, canonical labels, and short descriptions — from a name or phrase. Prefer it over Wikipedia search when you need machine-readable identifiers (Q-ids) for linking to a knowledge graph or semantic data pipeline. Use it over the multi-source sibling endpoint when you specifically want Wikidata results rather than a broad cross-source search.

• No matching entities found for the query — empty results array returned
• Query string exceeds 200 characters — likely rejected or truncated
• Limit parameter outside 1–10 range — may cause validation error or default fallback
• Wikidata service temporarily unavailable — degraded flag may be set to true
• Highly ambiguous or misspelled query — may return irrelevant or low-confidence matches
