## 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 timesheet-imports-header-contract-check-ac7aca2f -d '<json body>'
```

Example prompt: Can you run a header contract check on this timesheet CSV to make sure the columns and values are all valid? The file uses comma delimiters, allowed project categories are 'group-a' and 'group-b', and I want to check up to 1000 rows with a max cell length of 1000 characters.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) validation of a timesheet CSV's structural and value contract before importing into a payroll or HR system. It is purpose-built for timesheet schemas (entry_id, worked_on, project_id, worked_hours, hourly_rate) with support for configurable delimiters, numeric bounds, allowed category lists, and cell length constraints. Prefer it over generic CSV validators when the domain is specifically timesheet or time-tracking data with known column conventions.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only first 1000 processed or error returned
- Invalid delimiter specified — must be comma, semicolon, or tab
- Malformed CSV that cannot be parsed — error report returned
- allowed_categories list exceeds 100 items — validation error
- Cell length exceeds max_cell_length — flagged as contract violation
