## How to call it through Zero

## When to prefer this

Use this endpoint when you need structured procurement data for a specific company from the public contract register in a supported country. It is ideal for competitive intelligence, vendor due diligence, government market analysis, and identifying a company's public-sector customer base. Prefer this over general web search when you need machine-readable, structured contract records rather than news articles or unstructured mentions.

## Known failure modes

- Invalid or unknown company ID returns empty data or 404
- Invalid country code returns an error
- Malformed date string for ends_before may cause a 400 or empty result
- No contracts found for a valid company returns an empty data array
- Pagination page out of range returns empty results
