# Dataset Storage — Numeric Distribution + Equal-Width Histogram

> Dataset Storage — Numeric Distribution + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes numeric distribution statistics and an equal-width histogram for dataset storage records (used_mb, row_count) across up to 200 supplied rows.

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 dataset-storage-numeric-distribution-equal-width-histogram-0500e683 -d '<json body>'
```

Example prompt: Can you analyze the distribution of used_mb across these dataset storage records and give me a histogram with 10 equal-width bins? Here are 50 rows with row_id, dataset_group, date, used_mb, and row_count fields.

## When to prefer this

Choose this endpoint when you need both a numeric distribution summary and an equal-width histogram for dataset storage metrics (used_mb or row_count) in a single call, without requiring live data lookup or external computation. It is ideal for profiling storage consumption patterns from pre-collected records at low cost ($0.01 for up to 200 rows). Prefer alternatives if you need outlier flagging, deduplication, or analysis of fields beyond used_mb and row_count.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required row fields (row_id, dataset_group, date, used_mb, row_count) causes rejection
- Invalid date format (non-YYYY-MM-DD) fails schema validation
- Bins value outside 1–30 range triggers a parameter error
- All-null values for the selected field may produce empty or degenerate distribution output
- Payment failure (insufficient USDC) results in 402 response

## How this service works

Dataset storage — Numeric distribution + Equal-width histogram: Numeric distribution + Equal-width histogram for supplied dataset storage records (used_mb, row_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports for the specified field (used_mb or row_count): a numeric distribution summary (min, max, mean, median, std dev, etc.) and an equal-width histogram showing bin boundaries, midpoints, and frequency counts for the requested number of bins, all computed locally from the supplied rows.
