## 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 retail-listing-readiness-checks-dddb8a88 -d '<json body>'
```

Example prompt: Can you check my product CSV for listing readiness — validate titles against a 150-character limit, check ASIN formats, verify GTIN check digits, and flag any missing images or descriptions? Here's the CSV data with comma-delimited rows.

## When to prefer this

Choose this endpoint when you need fast, affordable bulk validation of seller-supplied product CSV data for common listing readiness criteria — missing fields, ASIN/GTIN format checks, image URL format, and title length — without needing Amazon category-specific compliance or official listing approval logic. Best suited for pre-flight data quality checks on up to 500 rows at $0.01 per call.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains no rows or is empty — validation error
- Invalid delimiter value supplied — request rejected
- Malformed CSV structure preventing parsing — error returned
- Title limit set outside 1–500 range — validation error
