# Procurement Research Numeric Distribution and Equal-Width Histogram

> Procurement Research Numeric Distribution and 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 2026-10-19).

Computes a numeric distribution summary and an equal-width histogram for quoted_amount or quoted_units fields in up to 200 procurement research rows, returning two independent analytical reports.

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 procurement-research-numeric-distribution-and-equal-width-histogram-81804e13 -d '<json body>'
```

Example prompt: I have 150 procurement records with quoted_amount and quoted_units fields — can you run a numeric distribution and equal-width histogram on the quoted_amount field using 10 bins?

## When to prefer this

Choose this endpoint when you need both a statistical distribution summary and a histogram visualization of procurement numeric fields (quoted_amount or quoted_units) in a single call for up to 200 rows, without requiring external data lookups or live market data. It is ideal for offline batch analysis of supplier quote datasets where you want two complementary views of numeric spread.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format in rows (must be YYYY-MM-DD)
- Missing required fields (row_id, company_group, date, quoted_amount, quoted_units) in any row
- bins parameter out of range (must be 1–30)
- All values null for chosen field — no distribution computable
- Malformed JSON input schema

## How this service works

Procurement research — Numeric distribution + Equal-width histogram: Numeric distribution + Equal-width histogram for supplied procurement research records (quoted_amount, quoted_units). 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 numeric distribution summary (min, max, mean, median, count, std dev, etc.) and (2) an equal-width histogram with configurable bin count, both computed on the chosen field (quoted_amount or quoted_units) from the supplied procurement rows.
