# Business Event Participation — Category Frequencies + Keyed Dataset Comparison

> Business Event Participation — Category Frequencies + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Analyzes business event participation records to produce category frequency distributions and a keyed comparison between two supplied datasets (up to 200 rows each, two reports per call).

## 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-keyed-dataset-65524ef6 -d '<json body>'
```

Example prompt: Can you run a category frequency analysis and keyed comparison on my business event participation data? I have two datasets — rows dataset has group-a with 10 attendees and 1 company on 2026-10-01, group-b with 20 attendees and 2 companies on 2026-10-02; other dataset is similar but group-a had 17 attendees on 2026-10-03. Give me the frequency breakdown by company_group and the row-by-row comparison.

## When to prefer this

Choose this endpoint when you need to simultaneously compute category-level frequency distributions and perform a keyed row-by-row comparison between two business event participation datasets (with attendee_count and company_count fields) in a single API call. It is purpose-built for event analytics workflows where both a summary view and a differential view across two datasets are needed together, without requiring external data sources or live lookups.

## Known failure modes

- Missing required fields (row_id, company_group, date, attendee_count, company_count) will cause validation errors
- More than 200 rows submitted will be rejected
- Invalid date format (not YYYY-MM-DD) will fail pattern validation
- Null or out-of-range numeric values beyond ±1,000,000,000,000 will be rejected
- Empty rows array will fail minItems:1 constraint
- Payment failure via x402 protocol will block execution

## How this service works

Business event participation — Category frequencies + Keyed dataset comparison: Category frequencies + Keyed dataset comparison 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 category frequency table showing how often each company_group value appears in the primary dataset, and (2) a keyed dataset comparison that aligns rows from the primary and secondary datasets by row_id and highlights differences in attendee_count and company_count fields.
