Example prompt: Can you look up Inditex in the Spanish Registro Mercantil and get me their CIF, VAT number, registered address, and current status?

## When to prefer this

Use this endpoint when you need to verify or enrich data about a Spanish-registered company, retrieve its official VAT/CIF number, confirm its registered address, or check its legal status. Prefer this over general web search when you need structured, authoritative registry data directly from the Registro Mercantil.

## Known failure modes

- Company not found by name or CIF — empty or null result
- Invalid CIF/NIF format — validation error returned
- Ambiguous company name match — may return closest fuzzy match or error
- Registry temporarily unavailable — upstream timeout or 5xx error
- No CIF or company_name provided — missing required parameter error
