# Vendor Evaluation — Record Quality Audit + Secondary-Measure Weighted Mean

> Vendor Evaluation — 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 2026-10-15).

Audits data quality of vendor evaluation records and computes a secondary-measure weighted mean for supplied_score and maximum_score fields, returning two analytical reports for up to 200 rows.

## 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 vendor-evaluation-record-quality-audit-secondary-measure-weighted-mean-cfb9caad -d '<json body>'
```

Example prompt: Can you run a record quality audit and compute the secondary-measure weighted mean on these vendor evaluation rows? I have up to 50 rows with row_id, company_group, date, supplied_score, and maximum_score fields — use supplied_score as the primary field.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a weighted mean computation on vendor evaluation records in a single $0.01 call, without requiring any external data lookup or live API access. It is ideal for batch preprocessing of up to 200 vendor scoring rows before reporting or analysis pipelines. Prefer this over generic stats tools when your data is structured around supplied_score and maximum_score fields with row-level company and date groupings.

## Known failure modes

- Empty or missing rows array returns validation error
- More than 200 rows submitted exceeds the row limit and will be rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Null values in both supplied_score and maximum_score may produce undefined weighted mean
- Missing required fields (row_id, company_group, date) cause row-level rejection
- Invalid field enum value (not supplied_score or maximum_score) causes parameter error

## How this service works

Vendor evaluation — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied vendor evaluation records (supplied_score, maximum_score). 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 missing, null, or anomalous values in the vendor evaluation records, and (2) a secondary-measure weighted mean calculated from the supplied_score and maximum_score fields across the submitted rows. Both reports are computed locally without external lookups.
