Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 transfer-record-imports-csv-record-key-uniqueness-validator-c0e2d264 -d '<json body>'
```

Example prompt: Check this transfer CSV for duplicate record keys — I have a comma-delimited file with columns transfer_id, executed_on, asset_id, sent_amount, received_amount and about 500 rows; make sure every transfer_id appears only once.

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC) automated check specifically for transfer record key uniqueness in CSV import files, especially when running pre-import validation pipelines for financial transfer data. Prefer it over generic CSV validators when you need a domain-specific transfer-oriented uniqueness report with support for allowed_categories filtering and configurable numeric bounds.

## Known failure modes

- CSV exceeds 1000 rows — only first 1000 may be evaluated
- CSV string exceeds 100,000 character limit — request rejected
- Invalid delimiter specified outside of comma, semicolon, or tab options
- Malformed CSV with unclosed quotes causing parse failure
- Cell length exceeds max_cell_length limit — row may be rejected
- Empty CSV string submitted — validation cannot proceed
