# Supplier Qualification Record Quality Audit + Equal-Width Histogram

> Supplier Qualification Record Quality Audit + 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).

Runs two local analytical reports on supplier qualification records: a data quality audit and an equal-width histogram over checked_criteria or met_criteria fields.

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 supplier-qualification-record-quality-audit-equal-width-histogram-2d79a89f -d '<json body>'
```

Example prompt: Run a record quality audit and equal-width histogram with 10 bins on the met_criteria field for these supplier qualification rows: [row-1, 2024-01-15, group-a, checked=10, met=7], [row-2, 2024-01-16, group-b, checked=20, met=15], [row-3, 2024-01-17, group-a, checked=12, met=9].

## When to prefer this

Choose this endpoint when you have up to 200 supplier qualification records and need both a data quality audit and a numeric frequency distribution (histogram) in a single low-cost call. It is ideal for procurement analysts who want to profile data completeness and value spread without connecting to external systems. Prefer it over general-purpose analytics tools when you need a bundled two-report output specifically scoped to checked_criteria and met_criteria fields at a fixed micro-payment cost.

## Known failure modes

- More than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) in any row — validation error
- bins parameter outside 1–30 range — rejected
- field value not one of checked_criteria or met_criteria — enum validation error
- Empty rows array — minItems violation
- row_id missing or empty — required field error
- Payment not completed via x402 protocol — 402 response

## How this service works

Supplier qualification — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram 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) a record quality audit covering completeness, null rates, and anomaly flags for the checked_criteria and met_criteria fields; and (2) an equal-width histogram of the selected field (checked_criteria or met_criteria) divided into the requested number of bins (1–30), showing frequency counts per bin. Both reports are computed locally on the supplied rows with no external lookups.
