# Company Headcount Observations — Trailing Mean Series + Explicit Missing-Value Fill

> Company Headcount Observations — Trailing Mean Series + Explicit Missing-Value Fill 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 fills missing values in company headcount observation data (headcount, open_roles) 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-trailing-mean-series-explicit-missing-b3f0a349 -d '<json body>'
```

Example prompt: I have headcount and open_roles observations for two company groups across several dates — can you compute a trailing mean series with a window of 4 and fill any missing headcount values using the median method?

## When to prefer this

Choose this endpoint when you have company-level headcount or open_roles time series data that needs rolling-window smoothing and/or missing-value imputation in a single pass. It is particularly suited for pre-processing HR or workforce data before visualization or forecasting, and handles up to 200 rows per call at low cost ($0.01 USDC). Prefer this over general analytics tools when you need both trailing mean computation and explicit null-fill in one bundled operation without requiring external data sources.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row rejection
- Missing required fields (row_id, company_group, date) trigger validation errors
- Window size larger than number of rows may produce NaN/null results for early rows
- Non-numeric values in headcount or open_roles fields cause processing errors
- Empty rows array returns an error

## How this service works

Company headcount observations — Trailing mean series + Explicit missing-value fill: Trailing mean series + Explicit missing-value fill 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 for the supplied rows: (1) a trailing mean series where each row's field value is replaced by the rolling mean over the specified window, and (2) the same dataset with explicit missing-value fill applied using the chosen method (zero, mean, or median). Results cover up to 200 rows of company headcount observations.
