Example prompt: Can you check this library loan CSV for exact duplicate rows? It uses a comma delimiter and has columns like loan_id, borrowed_on, branch_id, loan_days, and overdue_days — I want a full duplicates report before I import it.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) check for exact duplicate rows in a library loan CSV before importing into a system of record. It is purpose-built for loan import data with fields like loan_id, branch_id, borrowed_on, loan_days, and overdue_days, and supports quoted cells and configurable delimiters. Prefer this over a generic CSV tool when the domain is specifically library loan imports and you want a specialized preset with no external enrichment or side effects.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains fewer than 1 character — rejected as empty input
- Unsupported delimiter specified — only comma, semicolon, or tab allowed
- Cell content exceeds max_cell_length — parsing may fail or row skipped
- More than 1000 rows submitted — only first 1000 processed
- Malformed CSV structure — unmatched quotes or inconsistent columns may cause parse errors
