# Company Headcount Observations — Secondary-Measure Weighted Mean + Keyed Dataset Comparison

> Company Headcount Observations — Secondary-Measure Weighted Mean + Keyed Dataset Comparison 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 secondary-measure weighted mean on company headcount or open-roles data and compares two supplied datasets row-by-row, returning two analytical reports for up to 200 rows.

## 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-secondary-measure-weighted-mean-keyed-e0af6482 -d '<json body>'
```

Example prompt: Can you compute the open-roles-weighted mean of headcount across my company groups, and also compare these two sets of headcount observations to spot differences — I have two batches of up to 50 rows each, one for group-a and one for group-b, dated from 2024-01-01 through 2024-03-31?

## When to prefer this

Choose this endpoint when you have up to 200 rows of company headcount observations and need both a secondary-measure weighted mean (e.g. headcount weighted by open_roles) and a keyed row-level comparison between two datasets in a single low-cost call. Ideal for HR analytics, workforce reporting, or auditing headcount revisions without any external data dependencies.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required row fields (row_id, company_group, date, headcount, open_roles) cause validation errors
- Invalid date format (must match YYYY-MM-DD pattern) causes schema rejection
- All weight values (secondary measure) are null or zero, making weighted mean undefined
- Mismatched row_ids between the two datasets reduce the keyed comparison coverage

## How this service works

Company headcount observations — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison 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) a secondary-measure weighted mean of headcount or open_roles values using the other field as the weight, broken down by company group; (2) a keyed dataset comparison showing row-by-row differences between the two supplied datasets. Both reports are computed locally with no external data lookups.
