Example prompt: Can you check the date fields in my refund imports CSV for any calendar issues? Here's the CSV with a comma delimiter — make sure all dates in the refunded_on column fall between 2025-01-01 and 2026-12-31.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01 USDC) calendar date validation pass on a refund imports CSV file — especially when you want to catch malformed or out-of-range dates before committing data to a database or triggering downstream refund processing. Prefer it over general-purpose CSV validators when your data specifically follows the refund imports schema (refund_id, refunded_on, order_id, refund_amount, refunded_units).

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows in CSV — only up to 1000 rows processed
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell content exceeds max_cell_length — row flagged or rejected
- CSV is empty or missing date column — validation cannot proceed
- Date values outside min/max bounds — flagged as constraint violations
