# Supplier Qualification — Duplicate Key Report + Two-Measure Correlation

> Supplier Qualification — Duplicate Key Report + Two-Measure Correlation 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 row data: a duplicate key detection report and a Pearson/Spearman correlation between checked_criteria and met_criteria.

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-two-measure-correlation-f22d4e39 -d '<json body>'
```

Example prompt: Can you run a duplicate key check and a correlation analysis between checked_criteria and met_criteria on my supplier qualification dataset? Here are the rows: row-1, 2026-10-01, group-a, checked=10, met=1; row-2, 2026-10-02, group-b, checked=20, met=2; row-3, 2026-10-03, group-a, checked=15, met=3.

## When to prefer this

Choose this endpoint when you need fast, local-only data quality and statistical analysis on supplier qualification records without any external lookups or live data. It is ideal when you already have the dataset in hand and want to (a) detect duplicate row keys and (b) understand the statistical relationship between checked_criteria and met_criteria in a single low-cost call. Prefer alternatives if you need predictions, professional assessments, more than 200 rows, or analysis of more than two measures.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, company_group, checked_criteria, met_criteria) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Numeric values outside the allowed range (-1e12 to 1e12) rejected
- All checked_criteria or met_criteria values are null — correlation cannot be computed
- Single row submitted — correlation may be undefined or trivially 1
- Payment of 0.01 USDC not completed — endpoint returns 402

## How this service works

Supplier qualification — Duplicate key report + Two-measure correlation: Duplicate key report + Two-measure correlation 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 on the supplied rows: (1) a duplicate key report identifying any row_id values that appear more than once in the input, and (2) a two-measure correlation report quantifying the statistical relationship between the checked_criteria and met_criteria numeric fields across all submitted rows. No external data is fetched; all computation is performed locally on the provided data. Covers up to 200 rows per call.
