## 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 csv-training-data-column-statistics-validator-44f748b3 -d '<json body>'
```

Example prompt: Can you run column statistics on this training CSV — delimiter is comma, numeric values should stay between 0 and 1000000, max cell length 500, and allowed categories are group-a and group-b: '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 fast, affordable ($0.01 USDC) per-column statistical analysis and contract validation for CSV-formatted machine learning training data up to 1000 rows. It is ideal for pre-training data quality checks where you need to verify numeric bounds, categorical label integrity, and cell length constraints in a single call. Prefer it over general-purpose CSV tools when your use case is specifically training data validation with declared schema contracts.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows are validated
- CSV string exceeds 100,000 character limit — request rejected
- Cell content exceeds max_cell_length — validation failure flagged
- Category values not in allowed_categories list — contract violation reported
- Numeric values outside minimum/maximum bounds — out-of-range error returned
- Malformed CSV with unmatched quotes or inconsistent columns — parsing error
- Delimiter mismatch causing all data to appear as a single column

## How this service works

Training example metadata — Column statistics: Column statistics 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 column statistics report.

## Output

Returns a per-column statistics report for the submitted CSV, including validation results against numeric range bounds, allowed category values, and cell length limits. Each column is analyzed for type, distribution, and contract compliance within the declared constraints.
