# Business Event Participation — String Normalisation + Category Frequencies

> Business Event Participation — String Normalisation + Category Frequencies 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).

Normalises string fields and computes category frequency distributions for up to 200 business event participation records (attendee_count, company_count) in two independent analytical reports.

## 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-category-frequencies-79f03618 -d '<json body>'
```

Example prompt: I have a list of up to 200 business event participation records with company groups, dates, attendee counts, and company counts — can you normalise the string fields and give me a frequency breakdown of each category group?

## When to prefer this

Choose this endpoint when you have structured business event participation data (with attendee and company counts grouped by company_group) and need both string normalisation and category frequency analysis in a single low-cost call. It is ideal for pre-import data cleaning, quick exploratory aggregation on small-to-medium datasets (up to 200 rows), and batch reporting workflows where no live lookup or external data enrichment is needed.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, company_group, date, attendee_count, company_count) cause validation errors
- Malformed date strings not matching YYYY-MM-DD pattern rejected by schema
- Numeric values outside allowed range (-1e12 to 1e12) cause validation failure
- Empty rows array returns error due to minItems:1 constraint

## How this service works

Business event participation — String normalisation + Category frequencies: String normalisation + Category frequencies 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

Two independent analytical reports per call: (1) normalised string output for company_group and related string fields across all submitted rows, and (2) frequency distribution tables for categorical values in attendee_count and company_count fields — covering up to 200 input rows.
