## How to call it through Zero

Example prompt: Pull the structured Wikidata facts for SpaceX — I need the founders, HQ location, CEO, official website, and inception date. The Wikidata Q-id for SpaceX is Q193701.

## When to prefer this

Use this endpoint when you need authoritative, structured factual data about a known entity (company, organization, person, place) and already have or can look up its Wikidata Q-id. Ideal for enriching pipelines with canonical entity metadata, due diligence research, or filling in structured fields like founder, HQ, ticker, and website from a single trusted open knowledge source. Prefer this over web scraping or LLM-generated facts when you need citable, structured data.

## Known failure modes

- Invalid or non-existent Q-id returns an error or empty result
- Entity exists in Wikidata but has sparse data — many fields may be null or missing
- Wikidata data may be outdated relative to real-world changes (e.g. CEO changes)
- Payment failure via x402 protocol blocks the request
- Rate limiting or upstream Wikidata API unavailability
