# Training Example Metadata CSV Validation Summary

> Training Example Metadata CSV Validation Summary is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Validates a declared CSV table contract for training example metadata, returning a validation summary report including category checks, numeric range checks, and cell length constraints.

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 training-example-metadata-csv-validation-summary-60e6cd9f -d '<json body>'
```

Example prompt: Can you validate this training data CSV for me — it uses comma delimiters, allowed categories are 'group-a' and 'group-b', numeric values should be between 0 and 1000000, and max cell length is 500? Here's the CSV: 'example_id,created_on,label,text_length,sample_weight\nrecord-a,2026-01-01,group-a,10,2'

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01 USDC) contract-based validation of a training data CSV — particularly when you have explicit constraints like allowed category labels, numeric ranges, and cell length limits. It is ideal for ML data pipelines that need automated pre-flight checks on training example files before ingestion. It is not suitable for large datasets over 1000 rows (only the first 1000 are checked), external enrichment, or complex schema inference.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains fewer than 1 or zero characters — rejected
- Delimiter not one of comma, semicolon, or tab — rejected
- More than 100 allowed_categories specified — rejected
- CSV has more than 1000 rows — only first 1000 validated
- Malformed CSV with unmatched quotes — parse error returned
- Numeric values outside the -1,000,000,000,000 to 1,000,000,000,000 range for minimum/maximum parameters — schema error

## How this service works

Training example metadata — Validation summary: Validation summary 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 validation summary report.

## Output

A validation summary report covering: row count (up to 1000 rows), category conformance (whether all values are within allowed_categories), numeric range compliance (whether numeric cells fall within minimum/maximum bounds), cell length violations (cells exceeding max_cell_length), and an overall pass/fail indication. Quoted CSV cells are supported.
