# Customer Segment Observations — Equal-Width Histogram + IQR Outlier Flags

> Customer Segment Observations — Equal-Width Histogram + IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes equal-width histogram distribution and IQR-based outlier flags for customer segment observation records (account_count or revenue_amount) across 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 customer-segment-observations-equal-width-histogram-iqr-outlier-flags-a1788aba -d '<json body>'
```

Example prompt: Run an equal-width histogram with 10 bins and IQR outlier flagging on my customer segment data for the revenue_amount field — here are my rows: row-1 group-a 2024-01-01 account_count=50 revenue_amount=1200, row-2 group-b 2024-01-02 account_count=80 revenue_amount=9800, row-3 group-a 2024-01-03 account_count=45 revenue_amount=1100.

## When to prefer this

Choose this endpoint when you have up to 200 customer segment observation records and need both a distribution histogram and IQR outlier detection in a single paid call for either account_count or revenue_amount fields. It is well-suited for lightweight, self-contained statistical QA on tabular customer segment data without needing an external analytics platform.

## Known failure modes

- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format in rows — must match YYYY-MM-DD pattern
- Missing required row fields (row_id, company_group, date, account_count, revenue_amount)
- Bin count outside 1–30 range
- Invalid field selector — must be 'account_count' or 'revenue_amount'
- Null values in the selected numeric field may affect histogram or IQR calculations

## How this service works

Customer segment observations — Equal-width histogram + IQR outlier flags: Equal-width histogram + IQR outlier flags for supplied customer segment observations records (account_count, revenue_amount). 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) an equal-width histogram showing how values of the selected field (account_count or revenue_amount) are distributed across the specified number of bins, and (2) IQR-based outlier flags identifying which rows fall outside the interquartile range boundaries. Both reports are generated from the supplied row data using local analytical engines with no external lookups.
