# Supplier Qualification — Exact Row Deduplication + Secondary-Measure Weighted Mean

> Supplier Qualification — Exact Row Deduplication + 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).

Deduplicates supplier qualification records exactly by row and computes a weighted mean on a secondary measure (checked_criteria or met_criteria) across up to 200 rows, returning two analytical reports.

## 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-exact-row-deduplication-secondary-measure-89b0cf32 -d '<json body>'
```

Example prompt: I have a list of up to 200 supplier qualification records with fields row_id, company_group, date, checked_criteria, and met_criteria — can you deduplicate them exactly and compute a weighted mean on the met_criteria field, and give me the two analytical reports?

## When to prefer this

Choose this endpoint when you have a batch of supplier qualification records (up to 200 rows) and need both exact duplicate removal and a weighted mean computed on a secondary numeric measure (checked_criteria or met_criteria) in a single paid call. It is ideal for procurement analytics pipelines that require clean, deduplicated data summaries without any live lookups, predictions, or external integrations.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, company_group, date, checked_criteria, met_criteria) — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Invalid field enum value (must be 'checked_criteria' or 'met_criteria') — rejected
- All rows are duplicates, leaving no data for weighted mean — empty or degenerate report
- Numeric values outside allowed range (±1,000,000,000,000) — schema rejection
- Payment of 0.01 USDC not processed correctly — access denied

## How this service works

Supplier qualification — Exact row deduplication + Secondary-measure weighted mean: Exact row deduplication + 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

Two analytical reports: one showing the results of exact row deduplication across the supplied supplier qualification records, and one showing the secondary-measure weighted mean (for either checked_criteria or met_criteria) grouped by company_group. No external lookups or predictions are made; all computation is performed locally on the supplied data.
