# Business Event Participation — Base-100 Series + Explicit Missing-Value Fill

> Business Event Participation — Base-100 Series + Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Transforms business event participation records (attendee_count, company_count) into a Base-100 indexed series and fills missing values using zero, mean, or median imputation — up to 200 rows, 2 reports per call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-base-100-series-explicit-missing-value-bc7407b3 -d '<json body>'
```

Example prompt: I have 4 rows of business event data with attendee_count and company_count by date and group — can you generate a Base-100 indexed series for attendee_count using row index 0 as the base, and fill any missing values using median imputation?

## When to prefer this

Choose this endpoint when you have structured business event participation records (up to 200 rows) and need both Base-100 index normalization and missing-value imputation in a single call. It is ideal for offline/batch analytical preprocessing of event data without requiring any live data lookup or external API. Prefer this over general-purpose analytics tools when you want deterministic, local computation at very low cost ($0.01 per call for 2 reports).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- base_index out of bounds for the supplied rows array
- Invalid date format — must match YYYY-MM-DD pattern
- row_id missing or empty — required field per row
- Field enum value not recognized — must be attendee_count or company_count
- Method enum value not recognized — must be zero, mean, or median
- Payment of 0.01 USDC not confirmed — x402 payment required

## How this service works

Business event participation — Base-100 series + Explicit missing-value fill: Base-100 series + Explicit missing-value fill 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 event participation data: (1) a Base-100 indexed series for the specified field (attendee_count or company_count), rebased to the chosen row, and (2) the same dataset with missing values explicitly filled using the selected method (zero, mean, or median). Up to 200 input rows supported, processed locally with no external lookups.
