# Company Headcount Observations — Daily Sum Series & Secondary-Measure Weighted Mean

> Company Headcount Observations — Daily Sum Series & 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 a daily sum time series and a secondary-measure weighted mean over up to 200 supplied company headcount observation records (headcount and open_roles).

## 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-daily-sum-series-secondary-measure-d248caff -d '<json body>'
```

Example prompt: I have headcount and open_roles observations for two company groups (group-a and group-b) across four days in October 2026 — can you compute the daily sum series and the open_roles-weighted mean for the headcount field across all those rows?

## When to prefer this

Choose this endpoint when you have up to 200 rows of company headcount observation records and need both a daily sum time series and a weighted mean computed in a single call for a flat fee. It is ideal for lightweight HR analytics, workforce trend reporting, or recruiting dashboards where you supply the data and need fast, local statistical summaries without any external data lookups or predictions.

## Known failure modes

- Missing required fields (row_id, company_group, date, headcount, open_roles) cause validation errors
- More than 200 rows supplied exceeds the maxItems limit and will be rejected
- Dates not matching YYYY-MM-DD pattern will fail schema validation
- All-null values for the selected field may produce undefined or empty aggregation results
- Payment of 0.01 USDC must be included; missing payment results in 402 response

## How this service works

Company headcount observations — Daily sum series + Secondary-measure weighted mean: Daily sum series + 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 computed on the supplied rows: (1) a daily sum series aggregating the selected field (headcount or open_roles) by date, and (2) a secondary-measure weighted mean where one field is weighted by the other — all computed locally with no external lookups. Output covers up to 200 input rows.
