# CSV Training Data Whitespace Audit

> CSV Training Data Whitespace Audit is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates a CSV file's whitespace formatting and declared table contract, checking up to 1000 rows for whitespace issues in cells, headers, and values.

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 csv-training-data-whitespace-audit-0e3e7c6a -d '<json body>'
```

Example prompt: Can you audit this CSV for whitespace issues — it's my ML training data with columns example_id, created_on, label, text_length, and sample_weight, using a comma delimiter, and the only allowed label categories are group-a and group-b?

## When to prefer this

Choose this endpoint when you need a fast, low-cost whitespace-specific audit of a CSV training dataset (up to 1000 rows) before ingesting it into a machine learning pipeline. It is purpose-built for training data quality checks including category validation, numeric bounds, and cell length limits, and supports quoted cells — making it more appropriate than a generic CSV linter when the focus is on whitespace hygiene and declared schema contracts for ML data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — rejected as empty
- Delimiter not one of comma, semicolon, or tab — validation error
- max_cell_length outside 1–5000 range — parameter error
- allowed_categories list exceeds 100 items — parameter error
- Malformed CSV that cannot be parsed — error response
- Payment of 0.01 USDC not provided — 402 payment required

## How this service works

Training example metadata — Whitespace audit: Whitespace audit 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 whitespace audit report.

## Output

Returns a whitespace audit report for the submitted CSV, identifying cells, rows, or headers with leading/trailing whitespace, unexpected spacing, or values that violate the declared contract (allowed categories, numeric bounds, or max cell length), covering up to 1000 rows.
