## 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-grouped-numeric-summary-trailing-mean-d39d778d -d '<json body>'
```

Example prompt: I have 150 rows of business event participation records with attendee_count and company_count fields — can you give me a grouped numeric summary by company_group and also a trailing mean series for attendee_count with a window of 3?

## When to prefer this

Choose this endpoint when you have up to 200 business event participation records and need both a grouped numeric summary by company category and a trailing moving average series in a single low-cost call ($0.01 USDC). Ideal for offline batch analysis of event attendance or company participation data without needing real-time external data.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — rejected by schema validation
- Missing required fields (row_id, company_group, date, attendee_count, company_count) causes validation error
- Window size smaller than 2 or larger than 200 is rejected
- Date fields not matching YYYY-MM-DD pattern cause schema rejection
- Null values in numeric fields may affect mean calculations

## How this service works

Business event participation — Grouped numeric summary + Trailing mean series: Grouped numeric summary + Trailing mean series 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 for the supplied rows: (1) a grouped numeric summary of the specified field (attendee_count or company_count) broken down by company_group, and (2) a trailing mean series computed over the specified window size — both derived entirely from the submitted data with no external lookups.
