## 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 training-attendance-keyed-dataset-comparison-c9da3e3e -d '<json body>'
```

Example prompt: Compare these two training attendance datasets for me — the first has row-1 through row-4 with courses 'group-a' and 'group-b' and attendee counts of 10, 20, 15, 30, and the second has the same rows but attendee counts of 10, 21, 17, 33 — tell me which rows changed and by how much.

## When to prefer this

Choose this endpoint when you need a fast, local row-by-row numeric comparison of two training attendance datasets keyed by row_id — especially for auditing data changes, reconciling exports from different systems, or detecting data quality issues in attendee and completion counts. It is not suitable for forecasting, enrichment, or datasets larger than 200 rows.

## Known failure modes

- Rows array is empty or missing — returns validation error
- Row objects missing required fields (row_id, course, date, attendees, completions) — schema validation failure
- More than 200 rows submitted in either dataset — request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Numeric values outside allowed range — rejected with bounds error
- Payment not included or insufficient — x402 payment required response

## How this service works
