## 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-string-normalisation-grouped-numeric-d65a52b5 -d '<json body>'
```

Example prompt: I have 4 rows of business event participation data — group-a had 10 attendees and 1 company on 2026-10-01, group-b had 20 attendees and 2 companies on 2026-10-02, group-a had 15 attendees and 3 companies on 2026-10-03, and group-b had 30 attendees and 4 companies on 2026-10-04. Can you normalise the company group strings and give me a grouped numeric summary for attendee_count?

## When to prefer this

Choose this endpoint when you have structured business event participation records (with attendee and company counts per group and date) and need both string normalisation of group labels and grouped numeric aggregation in a single call — without any external API calls, predictions, or live data lookups. It is ideal for offline batch analysis of up to 200 rows at low cost ($0.01 USDC for two reports).

## Known failure modes

- Rows array is empty or exceeds 200 items — validation error
- Required fields (row_id, company_group, date, attendee_count, company_count) missing from one or more rows — schema validation failure
- Date field does not match YYYY-MM-DD pattern — rejected row or error
- Numeric values outside allowed range (-1e12 to 1e12) — validation failure
- Invalid field enum value (not attendee_count or company_count) — error response

## How this service works

Business event participation — String normalisation + Grouped numeric summary: String normalisation + 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 reports: (1) a string normalisation report cleaning the company_group field across submitted rows, and (2) a grouped numeric summary (e.g. totals, means, counts) for the selected numeric field (attendee_count or company_count) broken down by company_group — all computed locally with no external lookups.
