## 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 training-example-metadata-exact-row-duplicates-validator-25d4844d -d '<json body>'
```

Example prompt: Can you check my training example metadata CSV for exact duplicate rows? The CSV uses comma delimiters, and the allowed label categories are group-a and group-b — here's the data: example_id,created_on,label,text_length,sample_weight\nrecord-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3

## When to prefer this

Choose this endpoint when you need to specifically identify exact duplicate rows in a training example metadata CSV as part of a data quality or validation pipeline. It is purpose-built for training data schemas with fields like example_id, label, and sample_weight, and operates entirely offline with no external enrichment. Prefer it over general-purpose deduplication tools when you want a low-cost ($0.01 USDC), fast, contract-aware validation report scoped to ML training data.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows are supported
- CSV string exceeds 100,000 character limit
- Invalid delimiter specified outside of comma, semicolon, or tab
- Cell content exceeds max_cell_length limit
- Malformed CSV that cannot be parsed
- Category values not matching allowed_categories list
- Numeric values outside specified minimum/maximum bounds

## How this service works

Training example metadata — Exact row duplicates: Exact row duplicates for Training example metadata. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV exact row duplicates report.

## Output

A report identifying all exact duplicate rows within the submitted CSV, including which rows are duplicated and how many times, validated against the declared table contract (allowed categories, value ranges, cell length limits) for up to 1000 rows.
