# Company Headcount Observations — Numeric Distribution + Two-Measure Correlation

> Company Headcount Observations — Numeric Distribution + Two-Measure Correlation 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 numeric distribution (histogram) for a selected headcount field and a two-measure correlation between headcount and open_roles across up to 200 company headcount records.

## 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-numeric-distribution-two-measure-2864d5ab -d '<json body>'
```

Example prompt: Can you run a numeric distribution and correlation analysis on these company headcount records — I have up to 50 rows with headcount and open_roles for two groups, and I want to use headcount as the primary field?

## When to prefer this

Choose this endpoint when you have raw tabular company headcount data (up to 200 rows) and need both a distributional summary and a correlation between headcount and open_roles in a single low-cost call ($0.01 USDC). It is ideal for offline/batch analytical workflows where no live data lookup, prediction, or external enrichment is needed — just statistical computation over supplied records.

## Known failure modes

- Missing required fields (row_id, company_group, date, headcount, open_roles) will cause validation errors
- Exceeding 200 rows will be rejected by the API
- Invalid date format (not YYYY-MM-DD) will fail schema validation
- Null values in headcount or open_roles may reduce correlation reliability
- Sending fewer than 2 rows may produce degenerate or undefined correlation results
- Payment failure via x402 protocol will block the request

## How this service works

Company headcount observations — Numeric distribution + Two-measure correlation: Numeric distribution + Two-measure correlation 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 numeric distribution (histogram/frequency breakdown) of the selected field (headcount or open_roles) across the supplied rows, and (2) a two-measure correlation analysis between headcount and open_roles, all computed locally on the submitted data without any external lookup or prediction.
