# Supplier Qualification Duplicate Key Report + Adjacent Row Changes

> Supplier Qualification Duplicate Key Report + Adjacent Row Changes 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).

Analyzes supplier qualification records to identify duplicate row keys and compute adjacent row changes for checked_criteria or met_criteria fields across 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 supplier-qualification-duplicate-key-report-adjacent-row-changes-736a61c9 -d '<json body>'
```

Example prompt: Check my supplier qualification records for duplicate row keys and compute the adjacent row changes on the checked_criteria field — I have rows like row-1 through row-4 with company groups A and B dated 2026-10-01 through 2026-10-04 with checked_criteria values of 10, 20, 15, and 30.

## When to prefer this

Choose this endpoint when you need to perform two specific data-quality checks on supplier qualification records simultaneously — duplicate key detection and adjacent row change computation — against data you already have locally, without needing live external lookups, predictions, or professional assessments. It is ideal for procurement or supply chain data pipelines that need lightweight, low-cost validation and delta analysis on batches of up to 200 rows.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds the limit and is rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- row_id missing or empty string causes required field violation
- field enum value other than checked_criteria or met_criteria is rejected
- Numeric values outside ±1,000,000,000,000 are rejected
- Payment of 0.01 USDC not provided results in 402 payment required response

## How this service works

Supplier qualification — Duplicate key report + Adjacent row changes: Duplicate key report + Adjacent row changes 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 row_id values that appear more than once in the submitted dataset, and (2) an adjacent row changes report showing the difference between consecutive rows for the selected field (checked_criteria or met_criteria). Both reports are computed locally against the supplied data with no external lookups.
