## 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-calendar-date-check-57af9f61 -d '<json body>'
```

Example prompt: Can you check the date fields in my product imports CSV for any invalid calendar dates? Here's the CSV with comma delimiter — the allowed categories are group-a and group-b, and I want to validate up to 1000 rows.

## When to prefer this

Use this endpoint when you need to specifically validate calendar date columns in a product imports CSV before ingesting data into a product catalog or inventory system. It is purpose-built for the product imports domain with date-specific rules, category allowlists, and row-level reporting — making it more suitable than a generic CSV validator when date correctness and product category compliance are the primary concerns.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains fewer than 1 row of data — validation cannot proceed
- Delimiter mismatch causes parsing errors and incorrect column detection
- Category values not in allowed_categories list trigger category validation errors
- Cell length exceeds max_cell_length setting — row may be flagged or skipped
- Date values outside minimum/maximum bounds are reported as range violations
- Malformed date strings that cannot be parsed are flagged as format errors
