## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Search Wikidata in Japanese for '東京タワー' and give me the entity IDs, labels, and descriptions that come back.

## When to prefer this

Use this endpoint when you need to resolve Japanese-language terms to structured Wikidata entity identifiers (QIDs), labels, and descriptions — especially when building Japanese NLP pipelines, enriching Japanese content with linked data, or disambiguating Japanese proper nouns (people, places, organizations) against a knowledge graph. Prefer this over a generic Wikidata SPARQL query when you need a fast, simple text-search entry point specifically scoped to Japanese labels.

## Known failure modes

- Empty result set if the Japanese query term matches no Wikidata entities
- Malformed or missing q parameter returns an error or empty response
- Non-Japanese query may return fewer or no results since the search is tuned for Japanese
- Network or upstream Wikidata API timeout returning a 5xx error
- Rate limiting if called too frequently

## How this service works

Searches Wikidata entities in Japanese for the term q, returning ids, labels and descriptions. Query: ?q= Returns JSON.

## Output

A JSON array of Wikidata entities matching the Japanese query, each containing the entity ID (e.g. Q12345), its Japanese label, and a short Japanese-language description.
