## 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 payroll-input-imports-csv-header-contract-check-3013f159 -d '<json body>'
```

Example prompt: Can you check whether this payroll CSV file meets the expected import contract? The CSV uses comma delimiters, department IDs should only be 'dept-01' or 'dept-02', gross pay should be between 0 and 500000, and here's the data: 'pay_id,period_ends_on,department_id,gross_pay,deductions\nrec-1,2026-03-31,dept-01,4500,300'.

## When to prefer this

Choose this endpoint when you need a lightweight, affordable ($0.01 USDC) payroll-specific CSV validation that checks column headers, data types, numeric bounds, and category membership before ingesting data into a payroll system. It is purpose-built for payroll import schemas (pay_id, period_ends_on, department_id, gross_pay, deductions) rather than a generic CSV validator, making it ideal for teams automating payroll data pipelines that need a structured contract check report without external data enrichment.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only up to 1000 are validated
- Invalid delimiter specified (must be comma, semicolon, or tab)
- Cell value exceeds max_cell_length — flagged as a violation
- Numeric value outside declared minimum/maximum bounds — reported as contract breach
- Category value not in allowed_categories list — flagged per row
- Missing or malformed CSV header row — contract check fails with header error
