## 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-adjacent-row-changes-5c41ee66 -d '<json body>'
```

Example prompt: I have daily headcount records for a few company groups — can you compute the daily sum series and show adjacent row changes for the headcount field? Here are up to 200 rows with row_id, company_group, date, headcount, and open_roles.

## When to prefer this

Choose this endpoint when you have company headcount or open_roles records organized by date and company group and need both a daily aggregate sum series and consecutive-row change analysis in a single call. It is purpose-built for workforce time-series analytics on supplied data (no external lookups), handles up to 200 rows, and delivers two reports for a single low-cost call.

## Known failure modes

- Missing required fields (row_id, company_group, date, headcount, open_roles) causes validation error
- Date strings not matching YYYY-MM-DD pattern are rejected
- More than 200 rows submitted exceeds the row limit
- Null values in the selected numeric field may affect sum and delta calculations
- Invalid field enum value (not 'headcount' or 'open_roles') causes schema rejection
- Empty rows array rejected (minItems: 1)

## How this service works

Company headcount observations — Daily sum series + Adjacent row changes: Daily sum series + Adjacent row changes 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

Two analytical reports: (1) a daily sum series aggregating the selected field (headcount or open_roles) across all company groups by date, and (2) adjacent row changes showing the difference between consecutive rows for the selected field, enabling trend and delta analysis.
