# Company Headcount Observations — Trailing Mean Series + Keyed Dataset Comparison

> Company Headcount Observations — Trailing Mean Series + 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 trailing mean time series and a keyed dataset comparison for up to 200 rows of company headcount or open-roles data, returning two analytical reports per call.

## 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-trailing-mean-series-keyed-dataset-a521fb3b -d '<json body>'
```

Example prompt: I have two sets of daily headcount snapshots for our company groups — can you run a trailing mean series and a keyed comparison between them on the headcount field? Here's the primary dataset with rows like {row_id, company_group, date, headcount, open_roles} and the reference dataset to compare against.

## When to prefer this

Choose this endpoint when you need both a trailing mean time series and a keyed dataset comparison in a single call on company headcount or open-roles data. It is ideal for HR analytics, workforce trend smoothing, or comparing two headcount snapshots by key, particularly when you already have the data locally and want two bundled statistical reports for a flat $0.01 fee without any external lookups or live data dependencies.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — request rejected
- Missing required fields (row_id, company_group, date, headcount, open_roles) in any row — validation error
- Date fields not matching YYYY-MM-DD pattern — validation error
- Field value not in allowed enum ['headcount','open_roles'] — validation error
- Mismatched keys between primary and reference datasets may result in empty or partial comparison output

## How this service works

Company headcount observations — Trailing mean series + Keyed dataset comparison: Trailing mean series + 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 trailing mean series showing the rolling average of the selected field (headcount or open_roles) over time per company group, and (2) a keyed dataset comparison identifying differences between the primary and reference datasets matched by row key (row_id, company_group, date). No external data is fetched; all computation is performed locally on the supplied rows.
