## 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 library-loan-imports-valid-row-export-febe6d84 -d '<json body>'
```

Example prompt: Can you validate my library loan import CSV and give me only the valid rows? The file uses comma delimiters, allowed branch categories are group-a and group-b, and numeric values should be between 0 and 365.

## When to prefer this

Choose this endpoint when you need to validate library loan CSV imports specifically — it applies a domain-specific preset tuned for loan records (loan_id, borrowed_on, branch_id, loan_days, overdue_days) with support for category whitelisting, numeric range checks, and quoted cell parsing, all in a single low-cost call. Prefer it over generic CSV validators when your use case involves library loan data contracts and you need a clean export of only valid rows.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only up to 1000 processed
- Invalid delimiter value provided — must be comma, semicolon, or tab
- Cell content exceeds max_cell_length — row flagged as invalid
- Numeric values outside minimum/maximum bounds — rows excluded from valid export
- Category values not in allowed_categories list — rows excluded
- Malformed CSV that cannot be parsed — error returned
- Empty CSV string submitted — validation fails with no rows to process
