Example prompt: Can you check my property listings CSV for exact duplicate rows? Here's the CSV with columns listing_id, listed_on, region_id, asking_price, floor_area_sqm — use a comma delimiter and flag any rows that appear more than once.

## When to prefer this

Choose this endpoint when you need to validate a property listing CSV specifically for exact row-level duplicates before importing into a real estate database or portal. It is purpose-built for the property listings domain with relevant column semantics (listing_id, region_id, asking_price, floor_area_sqm), supports quoted cells, and costs only $0.01 USDC per check. Prefer this over generic CSV tools when your data follows the property listing schema and you need a fast, cheap duplicate detection pass without external enrichment.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains more than 1000 rows — exceeds row limit
- Cell content exceeds max_cell_length — validation error
- Invalid delimiter specified — must be comma, semicolon, or tab
- Malformed CSV that cannot be parsed — parsing error returned
- Category values not in allowed_categories list — validation failure
- Empty CSV submitted — minimum length not met
