# Company Headcount Observations — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Company Headcount Observations — Adjacent Row Changes + Secondary-Measure Weighted Mean 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 adjacent row-over-row changes and secondary-measure weighted mean for supplied company headcount observation records (headcount or open_roles), returning two analytical reports in one call.

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-adjacent-row-changes-secondary-measure-4ea8ee7e -d '<json body>'
```

Example prompt: Can you run adjacent row changes and a headcount-weighted mean on these company headcount records — I have 8 rows across two groups, group-a and group-b, with daily headcount and open_roles from 2024-01-01 to 2024-01-08, and I want to analyze the headcount field?

## When to prefer this

Choose this endpoint when you already have company headcount and open_roles data in hand and need two quick statistical analyses — adjacent row changes and a weighted mean — without any external data fetch, prediction, or enrichment. It is ideal for batch offline analysis of up to 200 rows in a single paid call, making it cost-efficient for periodic HR reporting workflows.

## Known failure modes

- Missing required fields (row_id, company_group, date, headcount, open_roles) cause validation errors
- More than 200 rows submitted exceeds the row limit and will be rejected
- Invalid date format (not YYYY-MM-DD) will fail schema validation
- Null values in the selected primary field may produce incomplete change calculations
- Payment of 0.01 USDC not provided causes x402 payment-required rejection

## How this service works

Company headcount observations — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean 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) adjacent row-over-row change values for the chosen field (headcount or open_roles) grouped by company_group and ordered by date, and (2) a secondary-measure weighted mean across the supplied rows — all computed locally from the provided data with no external lookup.
