## When to prefer this

Choose this endpoint when you need structured, encyclopedic facts about a named real-world entity (company, person, place, or work) sourced from Wikidata's open knowledge graph. Prefer it over web search when you want clean, machine-readable structured data rather than prose. Ideal for enriching records, resolving entity identity, or populating company/person profiles with canonical metadata.

## Known failure modes

- Entity name not found in Wikidata — returns empty or null result
- Ambiguous name matches multiple entities — returns 'otras_coincidencias' array requiring disambiguation
- Q-id not found — returns null or error
- Requested language not available for labels — may fall back to default language
- Missing optional facts — many 'hechos' fields may be null if Wikidata lacks the data

## How this service works

Structured facts from Wikidata about a person, company, place or work by name or Q-id: type, country, population, dates, founders, headquarters, website, ticker, currency, version... labelled in your language. Grounded answers without free text.

## Output

Returns a JSON object with the entity's Wikidata Q-id, label, description, Wikipedia URL, Wikidata source link, and a 'hechos' (facts) object containing structured fields such as country, headquarters, sector, founding date, founders, official website, stock exchange, revenue history, employee count, Twitter/X handle, GitHub repos, and entity type. Also includes an array of other disambiguation matches if the name is ambiguous.
