## How to call it through Zero

```sh
zero fetch --capability purchase-order-imports-csv-whitespace-audit-ca39a293 -d '<json body>'

Example prompt: Can you audit this purchase order CSV for whitespace issues — it uses comma delimiters and I need to check up to 1000 rows with a max cell length of 500, allowing only 'group-a' and 'group-b' as vendor categories? Here's the CSV: purchase_id,placed_on,vendor_id,ordered_units,order_amount\nrecord-a,2026-01-01,group-a,10,250.00

## When to prefer this

Choose this endpoint when you need a lightweight, affordable ($0.01 USDC) whitespace-specific audit of a purchase order CSV before importing it into an ERP or procurement system. It is purpose-built for PO import validation with support for quoted cells and configurable allowed categories, making it more targeted than a general CSV validator. Best suited for structured PO files with known column schemas (purchase_id, placed_on, vendor_id, ordered_units, order_amount).

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- Row count exceeds 1000 row maximum — partial or error response
- Invalid delimiter value outside allowed enum (comma, semicolon, tab)
- Malformed CSV that cannot be parsed — parse error returned
- Cell length exceeds configured max_cell_length — flagged or rejected
- Payment not attached or insufficient — 402 Payment Required
