## 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 payment-imports-csv-exact-row-duplicate-validator-6a46d352 -d '<json body>'
```

Example prompt: Check my payment import CSV for exact duplicate rows — the file uses comma delimiters and has columns payment_id, paid_on, invoice_id, paid_amount, processing_fee. Here's the CSV content: 'record-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3\nrecord-a,2026-01-01,group-a,10,2'. Tell me which rows are duplicated.

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC), purpose-built check specifically for exact row duplicates in payment import CSVs — particularly when your CSV follows a payment schema (payment_id, paid_on, invoice_id, paid_amount, processing_fee). Prefer this over general CSV tools when you want a lightweight, no-enrichment duplicate detection pass with support for quoted cells and configurable delimiters, up to 1000 rows.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — validation error
- More than 1000 rows submitted — may exceed preset row limit
- Cell length exceeds max_cell_length setting — row flagged or rejected
- Invalid delimiter value submitted — schema validation error
- Malformed CSV (unbalanced quotes, inconsistent columns) — parse error
