# Company Headcount Observations — Keyed Dataset Comparison + Explicit Missing-Value Fill

> Company Headcount Observations — Keyed Dataset Comparison + 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).

Compares two sets of company headcount observation records by key and fills missing values (headcount or open_roles) across up to 200 rows, producing two analytical reports.

## 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-keyed-dataset-comparison-explicit-56a1bc0b -d '<json body>'
```

Example prompt: I have two versions of our company headcount dataset — the original and an updated one — each with up to 50 rows including row_id, company_group, date, headcount, and open_roles. Can you compare them by key and fill in any missing headcount values, then give me two reports showing the differences and filled gaps?

## When to prefer this

Choose this endpoint when you have two structured company headcount or open_roles datasets that need to be compared row-by-row by key and have missing values filled in a single call. It is best for offline/batch analytical reconciliation of up to 200 rows of HR or workforce data without requiring live lookups, predictions, or external data enrichment. Prefer this over general-purpose data tools when you need both a keyed comparison and an explicit null-fill report delivered together at low cost.

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required fields (row_id, company_group, date, headcount, open_roles) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Field selector not one of 'headcount' or 'open_roles' — enum validation error
- Empty rows array — minimum items constraint violation
- Mismatched row_ids between primary and secondary datasets — comparison may produce incomplete results

## How this service works

Company headcount observations — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + 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: a keyed dataset comparison report showing differences between the two supplied datasets on the selected field (headcount or open_roles), and an explicit missing-value fill report showing which rows had null values and what they were filled with. No external data is fetched; all analysis is performed on the supplied rows only.
