Example prompt: Can you validate the date fields in this conversion aggregates CSV for me — make sure all the dates in the observed_on column are properly formatted calendar dates, using comma as the delimiter? Here's the CSV: observation_id,observed_on,channel_id,lead_count,conversion_count\nrecord-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3

## When to prefer this

Choose this endpoint when you need to validate calendar date fields specifically within a conversion aggregates CSV, especially when the data follows the observation_id/observed_on/channel_id/lead_count/conversion_count schema. It is purpose-built for this narrow preset and is cost-effective at $0.01 USDC per check. Prefer it over general CSV validators when your primary concern is date correctness in marketing or analytics conversion data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — validation may be truncated or refused
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell length exceeds max_cell_length limit — cell flagged or rejected
- Malformed CSV structure (unclosed quotes, inconsistent columns) — parse error returned
- No date column detected or column name mismatch — no date checks performed
