## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability purchase-order-imports-csv-column-statistics-4924f2e1 -d '<json body>'
```

Example prompt: Can you run column statistics on this purchase order CSV I have — it uses comma delimiters, vendor IDs should only be 'group-a' or 'group-b', and order amounts should be between 0 and 10000? Here's the CSV: purchase_id,placed_on,vendor_id,ordered_units,order_amount\nPO-001,2026-01-15,group-a,5,1500\nPO-002,2026-01-16,group-b,12,3400

## When to prefer this

Choose this endpoint when you need fast, structured column-level profiling and contract validation specifically for purchase order CSV data. It is ideal for pre-import quality gates, auditing vendor category compliance, and verifying numeric ranges on order fields without any external data enrichment. Prefer it over generic CSV tools when you need purchase-domain-aware profiling at a low per-call cost.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows are supported
- CSV string exceeds 100,000 character limit — payload too large
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell content exceeds max_cell_length — validation error flagged
- Malformed CSV (unmatched quotes, inconsistent columns) — parse error
- Numeric values outside declared minimum/maximum bounds — flagged as violations
- Allowed categories list is empty or contains values not found in data — mismatch warnings
