# Supplier Delivery Evidence — Duplicate Key Report + Adjacent Row Changes

> Supplier Delivery Evidence — 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 2026-10-16).

Analyzes up to 200 rows of supplier delivery data to produce two reports: a duplicate key detection report and an adjacent row change report, for the deliveries or on_time_deliveries field.

## 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-delivery-evidence-duplicate-key-report-adjacent-row-changes-ddf03f61 -d '<json body>'
```

Example prompt: Check my supplier delivery data for duplicate row keys and flag any adjacent row changes in the deliveries field — here are the records: row-1, group-a, 2026-10-01, 10 deliveries, 1 on-time; row-2, group-b, 2026-10-02, 20 deliveries, 2 on-time; row-3, group-a, 2026-10-03, 15 deliveries, 3 on-time.

## When to prefer this

Choose this endpoint when you need to simultaneously detect duplicate row keys AND inspect adjacent row changes in supplier delivery evidence data within a single low-cost call. It is ideal for lightweight, offline data quality auditing of delivery datasets (up to 200 rows) without requiring external data sources, live APIs, or prediction services.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, company_group, date, deliveries, on_time_deliveries) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Empty rows array returns error
- Invalid field enum value (not 'deliveries' or 'on_time_deliveries') causes rejection
- Payment of 0.01 USDC not provided — x402 payment required

## How this service works

Supplier delivery evidence — Duplicate key report + Adjacent row changes: Duplicate key report + Adjacent row changes for supplied supplier delivery evidence records (deliveries, on_time_deliveries). 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 independent analytical reports: (1) a duplicate key report identifying rows with repeated or conflicting key values, and (2) an adjacent row changes report highlighting value differences between consecutive rows for the selected field (deliveries or on_time_deliveries). Both reports are generated locally without external lookup, covering up to 200 input rows.
