# Metadata Completeness Duplicate Key Report + Secondary-Measure Weighted Mean

> Metadata Completeness Duplicate Key Report + 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 2026-10-27).

Analyzes metadata completeness records (present_fields, expected_fields) to produce a duplicate key report and a secondary-measure weighted mean, using local analytical engines on up to 200 rows.

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 metadata-completeness-duplicate-key-report-secondary-measure-weighted-60d100b0 -d '<json body>'
```

Example prompt: I have up to 200 metadata completeness records with row_id, site_group, date, present_fields, and expected_fields — can you run a duplicate key report and compute the secondary-measure weighted mean for the present_fields column on this data?

## When to prefer this

Choose this endpoint when you need both a duplicate key audit and a weighted mean computation on metadata completeness records (present_fields/expected_fields) in a single low-cost call. It is ideal for data quality pipelines that need to validate key uniqueness and summarize completeness metrics without external API calls or live data lookups. Best for datasets up to 200 rows processed locally.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, site_group, date, present_fields, expected_fields) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- present_fields or expected_fields outside allowed numeric range — rejected
- Empty rows array — minimum 1 row required

## How this service works

Metadata completeness — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + Secondary-measure weighted mean for supplied metadata completeness records (present_fields, expected_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

Returns two analytical reports: (1) a duplicate key report identifying repeated key combinations within the supplied metadata completeness rows, and (2) a secondary-measure weighted mean computed over the selected field (present_fields or expected_fields), all computed locally without external lookups.
