# Supplier Qualification Numeric Row Ordering + Equal-Width Histogram

> Supplier Qualification Numeric Row Ordering + 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).

Sorts supplier qualification records by a numeric field and produces an equal-width histogram distribution report for up to 200 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 supplier-qualification-numeric-row-ordering-equal-width-histogram-e1b5c2b7 -d '<json body>'
```

Example prompt: I have 50 supplier qualification records with checked_criteria and met_criteria values — can you sort them by checked_criteria and also generate an equal-width histogram with 8 bins so I can see the distribution?

## When to prefer this

Choose this endpoint when you need both a sorted ranking and a frequency histogram of supplier qualification numeric fields (checked_criteria or met_criteria) in a single call for up to 200 rows. It is ideal for procurement analysts who want a quick statistical overview of supplier qualification scores without setting up local analytics infrastructure. Prefer it over generic analytics platforms when working within an x402 micropayment workflow and needing lightweight, local-engine computation at low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — request rejected
- Bins parameter outside 1–30 range — validation error
- Rows missing required fields (row_id, date, checked_criteria, met_criteria) — schema validation failure
- All numeric field values are null — histogram cannot be computed
- Date field in wrong format (not YYYY-MM-DD) — pattern validation error

## How this service works

Supplier qualification — Numeric row ordering + Equal-width histogram: Numeric row ordering + 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 analytical reports: (1) the input rows sorted in ascending/descending numeric order by the selected field (checked_criteria or met_criteria), and (2) an equal-width histogram dividing the field's value range into the specified number of bins (1–30) with counts per bin — all computed locally from the supplied data with no external lookups.
