Example prompt: Can you check whether my transfer records CSV has a valid header contract — it uses a comma delimiter and the allowed asset categories are group-a and group-b? Here's the CSV: transfer_id,executed_on,asset_id,sent_amount,received_amount\nrecord-a,2026-01-01,group-a,10,2

## When to prefer this

Choose this endpoint when you need a lightweight, specialized validation of transfer record CSV headers and data contracts before importing into a downstream system. It is purpose-built for the transfer record schema (transfer_id, executed_on, asset_id, sent_amount, received_amount) with configurable category whitelists and numeric bounds, making it more targeted than a generic CSV validator.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains fewer than 1 character — rejected
- Delimiter not one of comma, semicolon, or tab — validation error
- Allowed category list exceeds 100 items — rejected
- Cell length exceeds configured max_cell_length — flagged in report
- Numeric values outside specified minimum/maximum range — flagged as contract violations
- Malformed CSV structure — parse error returned
