## 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 refund-imports-csv-record-key-uniqueness-validator-6aae0d32 -d '<json body>'
```

Example prompt: Check my refund imports CSV for duplicate record keys — here's the data: refund_id,refunded_on,order_id,refund_amount,refunded_units with comma delimiter. I want a uniqueness report so I can confirm every record key is distinct before loading it into our system.

## When to prefer this

Use this endpoint when you need to validate record key uniqueness specifically within refund import CSV data, especially as a pre-import data quality gate. Prefer this over generic CSV validators when working with refund-domain data that follows the refund_id/order_id/refund_amount schema, and when you need a lightweight per-call ($0.01 USDC) check without standing up custom deduplication logic.

## Known failure modes

- CSV exceeds 1000 rows — only first 1000 processed or error returned
- CSV string exceeds 100,000 character limit — rejected with size error
- Invalid delimiter specified outside allowed set (comma, semicolon, tab)
- Malformed CSV that cannot be parsed — parsing error returned
- Cell content exceeds max_cell_length limit — truncation or error
- Empty CSV string submitted — validation error
