## 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-category-allowlist-check-e9270a6a -d '<json body>'
```

Example prompt: Check my purchase orders CSV for any vendor categories that aren't in our approved list — allowed categories are 'group-a' and 'group-b', delimiter is comma, and here's the data: purchase_id,placed_on,vendor_id,ordered_units,order_amount\nrecord-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-c,20,3

## When to prefer this

Choose this endpoint when you need to validate that vendor or category fields in a purchase order CSV conform to a pre-defined whitelist of allowed values, especially in procurement or supply chain workflows. It is purpose-built for purchase order imports up to 1,000 rows and supports quoted cells and configurable delimiters, making it more specialized than a generic CSV validator.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1,000 rows submitted — only up to 1,000 rows supported
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell length exceeds max_cell_length setting — flagged or rejected
- Malformed CSV with unmatched quotes — parse error returned
- allowed_categories list exceeds 100 items — request rejected
