## 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-required-cell-check-067c75f1 -d '<json body>'
```

Example prompt: Check my purchase order CSV for missing required cells — here's the data with columns purchase_id, placed_on, vendor_id, ordered_units, order_amount, using a comma delimiter, and flag any rows that have empty required fields.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) automated check specifically for purchase order CSV imports to ensure all required cells are populated before ingestion into a downstream system. It is purpose-built for the purchase order domain with a specialized preset, making it more reliable than a generic CSV validator for PO-specific required field logic. Prefer it over general-purpose validators when working with procurement or ERP import pipelines that expect structured PO data with fields like purchase_id, placed_on, vendor_id, ordered_units, and order_amount.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains fewer than 1 character — rejected as empty input
- Delimiter mismatch causing cells to parse incorrectly — all rows may appear malformed
- More than 1000 rows submitted — only first 1000 may be validated or request rejected
- Invalid delimiter value outside allowed enum (comma, semicolon, tab) — schema validation error
- Cell length exceeds max_cell_length setting — flagged or truncated
