## 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 business-event-participation-duplicate-key-report-grouped-numeric-e3bdce54 -d '<json body>'
```

Example prompt: Check my business event participation data for duplicate row IDs and give me a grouped summary of attendee_count by company_group — here are 4 rows: row-1 on 2026-10-01, group-a, 10 attendees, 1 company; row-2 on 2026-10-02, group-b, 20 attendees, 2 companies; row-3 on 2026-10-03, group-a, 15 attendees, 3 companies; row-4 on 2026-10-04, group-b, 30 attendees, 4 companies.

## When to prefer this

Choose this endpoint when you need both a duplicate key detection report and a grouped numeric summary for business event participation data (attendee and company counts) in a single call. It is ideal for data quality checks on event datasets up to 200 rows where no external lookups or predictions are needed — pure local analytical computation on supplied data.

## Known failure modes

- Input array is empty or exceeds 200 rows — validation error
- row_id, company_group, or date fields missing or malformed — schema validation failure
- date field does not match YYYY-MM-DD pattern — rejected
- field enum value not 'attendee_count' or 'company_count' — invalid input
- numeric fields outside allowed range (±1 trillion) — validation error
- Payment not processed (x402 protocol failure) — no response returned

## How this service works

Business event participation — Duplicate key report + Grouped numeric summary: Duplicate key report + Grouped numeric summary for supplied business event participation records (attendee_count, company_count). 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 reports: (1) a duplicate key report identifying any row_ids that appear more than once in the supplied dataset, and (2) a grouped numeric summary aggregating the selected numeric field (attendee_count or company_count) by company_group — both computed locally without any external lookups.
