## 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-category-frequencies-numeric-row-ordering-f543f277 -d '<json body>'
```

Example prompt: I have 4 business event participation records — row-1 on 2026-10-01 with group-a, attendee_count 10 and company_count 1; row-2 on 2026-10-02 with group-b, attendee_count 20 and company_count 2; row-3 on 2026-10-03 with group-a, attendee_count 15 and company_count 3; row-4 on 2026-10-04 with group-b, attendee_count 30 and company_count 4 — can you give me the category frequencies for company_group and the numeric row ordering by attendee_count?

## When to prefer this

Choose this endpoint when you have up to 200 business event participation records and need both a category frequency count (by company_group) and a numeric ordering of rows by attendee_count or company_count in a single low-cost call. It is ideal for offline/batch analytical reporting on already-collected event data where no live lookup, prediction, or external data enrichment is needed.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds limit and is rejected
- Invalid date format (not YYYY-MM-DD) triggers schema validation failure
- Missing required fields (row_id, company_group, date) causes rejection
- Field selector not in allowed enum ('attendee_count' or 'company_count') returns validation error
- Numeric values outside allowed range (-1e12 to 1e12) are rejected

## How this service works

Business event participation — Category frequencies + Numeric row ordering: Category frequencies + Numeric row ordering 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 analytical reports on the supplied event participation rows: (1) a category frequency table showing how often each company_group value appears, and (2) a numeric row ordering of the records ranked by the selected numeric field (attendee_count or company_count). Both reports are computed locally from the submitted data with no external lookups.
