# Supplier Qualification — Equal-Width Histogram + Keyed Dataset Comparison

> Supplier Qualification — Equal-Width Histogram + Keyed Dataset Comparison 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).

Generates an equal-width histogram and a keyed dataset comparison report for supplier qualification records (checked_criteria, met_criteria) across up to 200 rows.

## 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 supplier-qualification-equal-width-histogram-keyed-dataset-comparison-c15eb8f0 -d '<json body>'
```

Example prompt: Take these two sets of supplier qualification records (up to 200 rows each) and give me an equal-width histogram with 10 bins on the checked_criteria field, plus a keyed comparison between the two datasets — I want to see where suppliers are falling short.

## When to prefer this

Choose this endpoint when you need both a frequency distribution (histogram) and a side-by-side keyed comparison of two supplier qualification datasets in a single call. It is best suited for procurement analysts who have already collected supplier records and want local, offline statistical analysis without any external lookups or predictions. Prefer this over generic analytics tools when your data is structured with row_id, company_group, date, checked_criteria, and met_criteria fields and fits within 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required fields (row_id, company_group, date, checked_criteria, met_criteria) — validation error
- bins value out of range (must be 1–30) — validation error
- Date format not matching YYYY-MM-DD pattern — validation error
- Payment not included or insufficient USDC — 402 payment required error
- Null values in numeric fields may affect histogram binning accuracy

## How this service works

Supplier qualification — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison for supplied supplier qualification records (checked_criteria, met_criteria). 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 independent analytical reports: (1) an equal-width histogram showing the distribution of the selected field (checked_criteria or met_criteria) across the specified number of bins, and (2) a keyed dataset comparison report aligning rows from the primary and secondary datasets by row_id to highlight differences in qualification metrics.
