## 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 wikidata-facts-person-profile-d486758f
```

Example prompt: Can you pull up the Wikidata biographical profile for Marie Curie — I want her birth date, place of birth, occupations, and citizenship?

## When to prefer this

Use this endpoint when you need structured biographical facts (birth, death, occupation, citizenship, identifiers) about a specific notable person and want Wikidata-sourced data with clean field separation. Prefer it over a general web search when you need machine-readable, citation-quality structured data rather than free text. Best suited for known public figures, historical persons, scientists, politicians, and celebrities with Wikipedia articles.

## Known failure modes

- Person not found in Wikidata — returns null or empty facts
- Ambiguous name with multiple candidates — requires disambiguation hint
- Private individual lookup rejected — endpoint only covers notable people with Wikipedia articles
- Wikidata upstream unavailable — service may return an error or timeout
- Incorrect Q-id supplied — returns facts for a different entity

## How this service works

Profile of a notable person with a Wikipedia article: birth, death, occupation, citizenship, identifiers. Never private people.

## Output

A structured JSON object containing the person's Wikidata Q-id, Wikipedia URL, and a facts object with date of birth (value, precision, calendar), date of death, place of birth, place of death, occupations (list of Q-id/label pairs), citizenship (list of Q-id/label pairs), and external identifiers such as VIAF, ISNI, GND, IMDb, and others. An asOf timestamp indicates data freshness.
