# Event Coverage Record Quality Audit + Secondary-Measure Weighted Mean

> Event Coverage Record Quality Audit + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Runs two analytical reports on event coverage data: a record quality audit and a secondary-measure weighted mean, processing up to 200 rows of covered/planned session data locally.

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 event-coverage-record-quality-audit-secondary-measure-weighted-mean-55361230 -d '<json body>'
```

Example prompt: Can you run a record quality audit and a weighted mean analysis on my event coverage data? I have rows with covered_sessions and planned_sessions across channel groups — here are up to 200 rows, and I want the weighted mean calculated on covered_sessions.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a weighted mean computation on event coverage session data in a single call, with no need for external data enrichment, live lookups, or predictions. It is especially useful for validating event planning datasets before reporting, or for quickly summarizing session coverage distributions across channel groups.

## Known failure modes

- Submitting more than 200 rows returns an error or truncated results
- Missing required fields (row_id, date, covered_sessions, planned_sessions) causes validation failure
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Null values in both numeric fields may reduce weighted mean reliability
- Empty rows array returns an error due to minItems:1 constraint

## How this service works

Event coverage — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied event coverage records (covered_sessions, planned_sessions). 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 record quality audit identifying issues such as missing values, null fields, or out-of-range entries across the supplied rows, and (2) a weighted mean of the selected secondary measure (covered_sessions or planned_sessions) across the dataset. Both reports are computed locally with no external lookups.
