# Evaluation Run Imports — CSV Column Statistics

> Evaluation Run Imports — CSV Column Statistics is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Validates a CSV of evaluation run import data and returns per-column statistics, supporting up to 1000 rows with configurable delimiters and cell 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 evaluation-run-imports-csv-column-statistics-9a435572 -d '<json body>'
```

Example prompt: Can you validate my evaluation run CSV and give me column statistics? Here's the data with comma delimiter — columns are evaluation_id, evaluated_on, dataset_id, correct_count, example_count — and I want to allow categories 'group-a' and 'group-b' with numeric values between 0 and 1000000.

## When to prefer this

Choose this endpoint when you need to validate and profile columns in a CSV of evaluation run import data — especially when you need to enforce numeric bounds, category allow-lists, and cell length constraints before importing into a pipeline. It is purpose-built for evaluation run schemas (evaluation_id, dataset_id, correct_count, etc.) rather than being a generic CSV profiler.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — empty input error
- Delimiter not in allowed set (comma, semicolon, tab) — validation error
- Cell exceeds max_cell_length limit — flagged or error
- More than 100 allowed_categories supplied — schema rejection
- Malformed CSV structure preventing parsing — parse error

## How this service works

Evaluation run imports — Column statistics: Column statistics for Evaluation run imports. 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 structured column statistics report for each column in the CSV, including data type inference, numeric range checks, category membership validation, cell length violations, and summary counts — covering up to 1000 rows per call.
