## 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-trailing-mean-series-2f0384da -d '<json body>'
```

Example prompt: Can you run a duplicate key report and a trailing mean series with a window of 3 on my business event participation data — I have about 50 rows tracking attendee_count grouped by company, and I want to analyze the attendee_count field?

## When to prefer this

Choose this endpoint when you need both a data-quality duplicate-key check and a trailing/rolling mean time series on business event participation records in a single low-cost call. It is ideal for event analytics workflows where you already have the data locally and need two independent statistical summaries without any external data enrichment, live lookups, or predictions.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected, exceeds maximum
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Window size smaller than 2 or larger than 200 — rejected
- Missing required fields (row_id, company_group, date, attendee_count, company_count) — validation error
- Non-numeric values in attendee_count or company_count where numbers are expected — type error
- Payment of 0.01 USDC not received — 402 Payment Required

## How this service works

Business event participation — Duplicate key report + Trailing mean series: Duplicate key report + 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 independent analytical reports: (1) a duplicate key report identifying any repeated row_id values in the supplied records, and (2) a trailing mean series for the selected numeric field (attendee_count or company_count) computed with the specified rolling window size. Both reports are derived locally from the submitted data without any external lookups.
