## 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`):

```sh
zero fetch --capability suverse-wikidata-entity-lookup-e02b4cfc -d '<json body>'
```

Example prompt: Can you fetch the Wikidata entity data for Q42 — I need its canonical labels, descriptions, aliases, and claims in all available languages.

## When to prefer this

Choose this endpoint when you need structured, authoritative Wikidata facts for a known entity identified by its Q-id — especially when you require cross-language labels, canonical descriptions, or machine-readable claims without needing to authenticate with Wikidata directly. It is ideal for knowledge graph enrichment, entity disambiguation, and multilingual NLP pipelines.

## Known failure modes

- Invalid or non-existent Q-id returns empty or error response
- Wikidata API rate limiting or downtime causes timeout
- Malformed request body yields a 400 error
- Very large entities with many claims may have slow response times
- Some Q-ids may have sparse data with few labels or claims

## How this service works

Structured Wikidata entity data by Q-id via the Wikidata API, no key. Returns labels, descriptions, aliases, claims, and sitelinks. For agents resolving entities to canonical facts and cross-language labels.

## Output

A structured JSON object containing the Wikidata entity's labels (by language), descriptions (by language), aliases, claims (property-value pairs representing facts), and sitelinks to Wikipedia and other Wikimedia projects.
