Wikidata

Mode: 🌐 Public · Domain: www.wikidata.org

Search Wikidata items by keyword and fetch full entity detail by Q/P/L identifier. Wikidata is the canonical structured-data registry behind Wikipedia, with ~110M entities and a global property graph.

Commands

Command	Description
opencli wikidata search <query>	Search Wikidata items by label / alias (returns Q-IDs)
opencli wikidata entity <id>	Full entity detail: label, description, aliases, claim & sitelink counts

Usage Examples

# Find Q-IDs by keyword
opencli wikidata search einstein
opencli wikidata search "san francisco" --limit 10
opencli wikidata search 哈尔滨 --language zh

# Entity detail (Q-IDs round-trip from search)
opencli wikidata entity Q937           # Albert Einstein
opencli wikidata entity Q90            # Paris
opencli wikidata entity Q937 --language zh

Output Columns

Command	Columns
search	rank, qid, label, description, matchType, matchText, url
entity	qid, type, label, description, aliases, claimPropertyCount, sitelinkCount, enwikiTitle, modified, url

The qid column round-trips between commands.

Options

search

Option	Description
query (positional)	Search keyword (matches labels and aliases)
--language	Search & display language (ISO 639, default: en). Examples: en, fr, zh, zh-hans.
--limit	Max items (1–50, default: 20)

entity

Option	Description
id (positional)	Entity id: Q<digits> (item), P<digits> (property), L<digits> (lexeme). Full URLs (https://www.wikidata.org/wiki/Q937) are stripped.
--language	Display language (ISO 639, default: en). Falls back to English when missing.

Notes

• Label / description / aliases fall back to English when the requested language is missing — Wikidata stores localisations independently per field, so a Chinese-only article may have an English label but no Chinese description, and we surface what's available rather than emitting null row-by-row.
• claimPropertyCount ≠ claim count. It counts the number of distinct properties (P-IDs) on the entity. Some properties have many statements (e.g. P31 may have multiple "instance of" claims); we don't sum them. Useful as a rough indicator of how rich the entity is.
• sitelinkCount is the number of language Wikipedias linking to this entity. High values (300+) indicate broadly-known concepts.
• enwikiTitle is the corresponding English Wikipedia article title, if any. null for entities not linked to enwiki (Q-IDs that exist only as Wikidata structured data).
• matchType (search only) is one of label, alias, description, indicating how the keyword matched. alias matches are common for famous entities (e.g. searching "Einstein" matches Q937 via alias, not label).
• No API key required. Wikidata throttles anonymous traffic at ~5000 req/hour; bursts → CommandExecutionError.
• Errors. Bad Q-ID shape / bad language code / bad limit → ArgumentError; unknown id → EmptyResultError; transport / 429 / non-200 → CommandExecutionError.
