# Company Headcount Observations — Duplicate Key Report + Secondary-Measure Weighted Mean

> Company Headcount Observations — Duplicate Key Report + 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).

Runs two analytical reports on user-supplied company headcount data: a duplicate key detection report and a weighted mean calculation for headcount or open_roles, supporting up to 200 rows 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-duplicate-key-report-secondary-measure-8150573b -d '<json body>'
```

Example prompt: Check my company headcount observations for duplicate row IDs and compute the weighted mean of headcount across these records — here are up to 200 rows with fields row_id, company_group, date, headcount, and open_roles.

## When to prefer this

Choose this endpoint when you need to simultaneously check a batch of company headcount observations for duplicate keys AND compute a weighted mean for headcount or open_roles, and your dataset is 200 rows or fewer. It is ideal for pre-ingestion data quality validation or quick analytical summaries on supplied data without needing any external data sources or live lookups. Not suitable for datasets exceeding 200 rows, for live headcount lookups, or for operations requiring more than two report types.

## Known failure modes

- Missing required fields (row_id, company_group, date, headcount, or open_roles) cause validation errors
- Supplying more than 200 rows exceeds the maxItems limit and will be rejected
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Null values in both numeric fields may affect weighted mean computation
- Empty rows array (minItems: 1 not met) returns an error
- Invalid field enum value (anything other than 'headcount' or 'open_roles') causes rejection

## How this service works

Company headcount observations — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + 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 independent analytical reports: (1) a duplicate key report identifying any rows with repeated key combinations (row_id, company_group, date), and (2) a secondary-measure weighted mean for the chosen field (headcount or open_roles) across all supplied rows. Results are computed locally on the supplied data with no external lookups.
