# Company Headcount Observations — Category Frequencies + IQR Outlier Flags

> Company Headcount Observations — Category Frequencies + 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 2026-10-19).

Computes category frequency distributions and IQR-based outlier flags for supplied company headcount and open-roles observation records (up to 200 rows, 2 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 company-headcount-observations-category-frequencies-iqr-outlier-flags-6493bb5a -d '<json body>'
```

Example prompt: Analyze these 50 company headcount observations across our groups — for the headcount field, give me the category frequencies by company_group and flag any IQR outliers so I can spot which records are anomalous.

## When to prefer this

Use this endpoint when you have raw company headcount or open-roles tabular data (up to 200 rows) and need both a categorical frequency distribution and IQR-based outlier detection in a single low-cost call. Ideal for HR analytics, data quality audits, or pre-processing steps before importing workforce data into a BI system. Prefer this over general-purpose statistics APIs when you specifically need the company_group breakdown paired with outlier flags in one response.

## Known failure modes

- Input array is empty or exceeds 200 rows — validation error returned
- Required fields (row_id, company_group, date, headcount, open_roles) missing from one or more rows — schema rejection
- Date field does not match YYYY-MM-DD pattern — validation error
- Field enum value is not 'headcount' or 'open_roles' — rejected
- All values are null for the selected field — IQR computation cannot proceed
- Payment of 0.01 USDC not included or fails — 402 response, no analysis returned

## How this service works

Company headcount observations — Category frequencies + IQR outlier flags: Category frequencies + IQR outlier flags for supplied company headcount observations records (headcount, open_roles). 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) category frequency counts/distributions broken down by company_group for the selected field (headcount or open_roles), and (2) IQR-based outlier flags identifying which rows fall outside the interquartile range, all computed locally against the supplied data with no external lookups.
