```sh
zero fetch --capability rotary-agency-wikidata-api-59bb32ee
```

Example prompt: Can you look up the Wikidata entry for Marie Curie and pull her birth date, nationality, and notable awards?

## When to prefer this

Choose this endpoint when you need quick, pay-per-call access to Wikidata structured data without managing your own Wikidata API integration or SPARQL queries. Best for agents that need occasional entity lookups at low cost ($0.002/call) without rate-limit concerns of direct Wikidata access.

## Known failure modes

- Invalid or non-existent Wikidata QID returns empty or error response
- Rate limit or payment verification failure returns 402 Payment Required
- Malformed query parameters may result in 400 Bad Request
- Entity exists but has sparse data, returning minimal fields
- Network timeout if Wikidata upstream is slow
