# Supplier Qualification — Duplicate Key Report + Secondary-Measure Weighted Mean

> Supplier Qualification — 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 2026-10-15).

Runs two local analytical reports on supplied supplier qualification records: a duplicate key report and a secondary-measure weighted mean calculation, for 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 supplier-qualification-duplicate-key-report-secondary-measure-63ebcb70 -d '<json body>'
```

Example prompt: Check my supplier qualification records for duplicate row IDs and also compute the weighted mean of checked_criteria — I have about 50 rows with fields: row_id, company_group, date, checked_criteria, and met_criteria.

## When to prefer this

Choose this endpoint when you need to simultaneously detect duplicate row IDs and compute a weighted mean for supplier qualification records in a single low-cost call. It is best suited for batch data quality checks on procurement or supplier onboarding datasets of up to 200 rows where no live external lookup or prediction is needed.

## Known failure modes

- More than 200 rows submitted — request exceeds maxItems limit
- Missing required fields (row_id, company_group, date, checked_criteria, met_criteria) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — validation error
- Empty rows array — minItems constraint violated
- Invalid field enum value — must be 'checked_criteria' or 'met_criteria'

## How this service works

Supplier qualification — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + Secondary-measure weighted mean for supplied supplier qualification records (checked_criteria, met_criteria). 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 duplicate key report identifying any rows with repeated row_id values, and (2) a weighted mean calculation for the selected secondary measure field (checked_criteria or met_criteria) across the supplied rows. Up to 200 rows processed per call.
