# Data Catalog Coverage — String Normalisation + Secondary-Measure Weighted Mean

> Data Catalog Coverage — String Normalisation + 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).

Normalises strings and computes a secondary-measure weighted mean for data catalog coverage records (documented_fields, total_fields) across up to 200 rows, returning two 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-string-normalisation-secondary-measure-weighted-5e0fb167 -d '<json body>'
```

Example prompt: Can you normalise the dataset group strings and compute a secondary-measure weighted mean for my catalog coverage data — I have rows with documented_fields and total_fields values, and I want the weighted mean calculated over documented_fields across groups like 'group-a' and 'group-b' for dates in October 2026?

## When to prefer this

Choose this endpoint when you need both string normalisation of categorical group labels AND a secondary-measure weighted mean on data catalog coverage fields in a single call, without requiring external data sources or live lookups. Ideal for batch analysis of up to 200 catalog coverage rows where you want grouped, weighted quality metrics in one low-cost operation.

## Known failure modes

- More than 200 rows submitted — request exceeds row limit and will be rejected
- Missing required fields (row_id, dataset_group, date, documented_fields, total_fields) causes validation failure
- Invalid date format (not YYYY-MM-DD) triggers schema validation error
- Null values in both documented_fields and total_fields may produce undefined weighted mean
- field enum value not matching 'documented_fields' or 'total_fields' causes rejection
- Payment of 0.01 USDC not provided or x402 protocol failure prevents processing

## How this service works

Data catalog coverage — String normalisation + Secondary-measure weighted mean: String normalisation + 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 analytical reports covering: (1) normalised string output for the dataset_group field across the submitted rows, and (2) a secondary-measure weighted mean of the selected field (documented_fields or total_fields) computed using the other measure as weighting, returned as structured local analysis with no external lookups.
