## 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 invoice-imports-csv-required-cell-check-69c47d48 -d '<json body>'
```

Example prompt: Check my invoice CSV for missing required cells — it has columns invoice_id, issued_on, account_id, net_amount, and tax_amount, with comma as the delimiter, and the allowed category values are group-a and group-b.

## When to prefer this

Choose this endpoint when you need to validate invoice-specific CSV files for required cell completeness before importing into an accounting or ERP system. It is purpose-built for invoice CSV schemas (invoice_id, issued_on, account_id, net_amount, tax_amount) with support for category allowlists and numeric range constraints. Prefer it over generic CSV validators when the domain is invoicing and you need a fast, low-cost ($0.01 USDC) completeness check without external data enrichment.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- Fewer than 1 or more than 5000 characters per cell exceeds max_cell_length constraint
- Invalid delimiter value (must be comma, semicolon, or tab)
- Malformed CSV that cannot be parsed — validation fails with parse error
- CSV exceeds 1000 rows — only first 1000 may be processed or request rejected
- Numeric value outside the allowed minimum/maximum range
