## 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-valid-row-export-b8dbe572 -d '<json body>'
```

Example prompt: Can you validate my training data CSV and export only the valid rows? The file uses comma delimiters, labels should only be 'group-a' or 'group-b', numeric values should be between 0 and 1000000, and max cell length is 1000 characters.

## When to prefer this

Choose this endpoint when you need to validate a CSV dataset of training examples against a declared schema contract — including numeric bounds, category allowlists, and cell length limits — and receive back only the clean, passing rows. Best suited for ML data preparation pipelines where you need a quick, affordable ($0.01) quality gate on up to 1000 rows without any external data enrichment.

## Known failure modes

- CSV exceeds 100,000 character input limit — request rejected
- CSV has fewer than 1 valid row after filtering — empty export returned
- Delimiter mismatch causes all rows to fail parsing
- Allowed categories list is empty and no rows match — empty result
- Numeric values in CSV are non-parseable strings — those rows flagged invalid
- Cell length exceeds max_cell_length causing rows to be excluded
- Malformed quoted cells may cause parsing errors

## How this service works

Training example metadata — Valid row export: Valid row export 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 valid row export report.

## Output

A valid row export report containing only the CSV rows that pass all declared constraints — including numeric range checks, category allowlist filtering, and cell length limits — covering up to 1000 rows of the input CSV.
