## 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 saylor-innovations-data-desk-wikidata-entity-facts-70f05a03
```

Example prompt: What are the key facts about Elon Musk — like his birthdate, occupation, nationality, and any awards he's won?

## When to prefer this

Choose this endpoint when you need structured, machine-readable encyclopedic facts about a named entity (person, company, or place) and want a single clean JSON response rather than scraping Wikipedia or querying Wikidata's SPARQL API directly. It is ideal for enriching records with authoritative metadata like founding dates, headquarters, population, or coordinates without building a Wikidata integration yourself.

## Known failure modes

- No matching entity found for the query string — returns empty or null facts
- Ambiguous name resolves to unexpected entity — check 'other_matches' array for alternatives
- Wikidata record exists but lacks specific fields — some fact properties may be null
- Rate limiting or payment failure for the x402 micropayment — request not processed
- Misspelled or variant name forms may fail to match the canonical Wikidata label

## How this service works

Wikidata entity facts - structured facts for any person, company or place: dates, occupation, country, awards, headquarters, population, coordinates and website

## Output

Returns a JSON object containing the Wikidata entity ID, a human-readable label, a short description, dates (birth/death, founding/dissolution), structured facts (occupation, country, awards, headquarters), population, geographic coordinates, area in km², website, Wikipedia URL, number of Wikipedia language editions, the canonical URL, the interpreted query string, the data source, the check timestamp, and an array of other candidate matches that also fit the query.
