# Data Catalog Coverage — Record Quality Audit + Secondary-Measure Weighted Mean

> Data Catalog 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 2026-10-23).

Audits record quality and computes a secondary-measure weighted mean for data catalog coverage records (documented_fields, total_fields) across up to 200 rows, returning two independent analytical reports.

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 data-catalog-coverage-record-quality-audit-secondary-measure-weighted-8baf28dc -d '<json body>'
```

Example prompt: Run a record quality audit and compute the secondary-measure weighted mean on these data catalog coverage rows — I have fields like row_id, dataset_group, date, documented_fields, and total_fields for about 50 records across two groups, and I want both reports back.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a weighted mean computation on data catalog coverage records (documented_fields/total_fields) in a single low-cost call. Ideal for data governance workflows where you want to assess documentation completeness across dataset groups without any external API calls or live data lookups. Best suited for batch sizes up to 200 rows where two bundled analytical reports justify the flat $0.01 USDC fee.

## Known failure modes

- Exceeding 200 rows returns an error or truncated result
- Missing required fields (row_id, dataset_group, date, documented_fields, total_fields) causes validation failure
- Null values in documented_fields or total_fields may affect weighted mean computation
- Invalid date format (not YYYY-MM-DD) triggers schema validation error
- Submitting zero rows fails minItems constraint

## How this service works

Data catalog coverage — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied data catalog coverage records (documented_fields, total_fields). 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: (1) a record quality audit covering the supplied data catalog coverage rows, flagging data issues and quality metrics; and (2) a secondary-measure weighted mean computation for the selected field (documented_fields or total_fields) across the provided rows, grouped by dataset_group and date. Both reports are generated locally without external lookups.
