Example prompt: Can you check that this price quote CSV file has the right headers and data contract — columns are quote_id, quoted_on, supplier_id, unit_price, minimum_quantity, delimiter is comma, allowed supplier categories are group-a and group-b, and unit prices should be between 0 and 500?

## When to prefer this

Choose this endpoint when you need to validate the structural and contractual integrity of a price quote CSV file before importing it into a downstream system, especially when you need to enforce column presence, allowed category values, and numeric range constraints. It is purpose-built for price quote import workflows and supports quoted cells, making it more reliable for supplier data than generic CSV validators.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — request rejected
- Delimiter not one of comma, semicolon, or tab — validation error
- More than 100 allowed_categories specified — request rejected
- max_cell_length outside 1–5000 range — validation error
- Malformed CSV that cannot be parsed — parsing error returned
- Numeric minimum or maximum out of supported range — error returned
