## 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 product-imports-csv-header-contract-check-2e6c3657 -d '<json body>'
```

Example prompt: Can you check my product import CSV to make sure the headers and data are valid? The CSV uses comma delimiters, allowed categories are 'electronics' and 'apparel', prices should be between 0 and 9999, and here's the data: sku,introduced_on,category_id,list_price,unit_weight_kg\nitem-1,2026-03-01,electronics,49.99,0.5

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) automated check that a product import CSV conforms to a declared header contract before ingesting it into a catalog system. It is ideal for CI/CD data pipelines, pre-upload validation gates, or any workflow where catching schema violations early (wrong categories, out-of-range prices, malformed headers) saves downstream processing costs. It supports quoted cells and multiple delimiters, making it suitable for CSV files exported from various tools.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only first 1000 validated
- Invalid delimiter specified — must be comma, semicolon, or tab
- Empty CSV string submitted — validation cannot proceed
- Category values not in allowed_categories list — flagged as violations
- Cell length exceeds max_cell_length — reported as error

## How this service works
