# Commercial Proposal Comparisons — Duplicate Key Report + Secondary-Measure Weighted Mean

> Commercial Proposal Comparisons — Duplicate Key Report + 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 2026-10-17).

Analyzes commercial proposal comparison data to produce a duplicate key report and a secondary-measure weighted mean report for quoted_amount or delivery_days fields.

## 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 commercial-proposal-comparisons-duplicate-key-report-secondary-2ec86c59 -d '<json body>'
```

Example prompt: Can you run a duplicate key report and a weighted mean analysis on my commercial proposal data? I have rows with company groups like 'group-a' and 'group-b', quoted amounts and delivery days, and I want to check the quoted_amount field for duplicates and weighted averages — here are up to 200 rows.

## When to prefer this

Choose this endpoint when you need two specific analytical reports — duplicate key detection and weighted mean computation — on commercial proposal or vendor bid data (quoted amounts and delivery days) in a single low-cost call. It is ideal for data quality audits and procurement analytics on datasets up to 200 rows where no external data lookup or prediction is needed, and where the $0.01 USDC flat rate for both reports together is cost-efficient.

## Known failure modes

- Missing required fields (row_id, company_group, date, quoted_amount, delivery_days) cause validation errors
- Submitting more than 200 rows exceeds the maximum and will be rejected
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation error
- Selecting a field value outside the enum ['quoted_amount','delivery_days'] returns an error
- Numeric values outside the allowed range (-1e12 to 1e12) are rejected
- Empty rows array (minItems:1 not met) causes a request error

## How this service works

Commercial proposal comparisons — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + Secondary-measure weighted mean for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 analytical reports: (1) a duplicate key report identifying rows with repeated row_id or company_group keys in the submitted dataset, and (2) a secondary-measure weighted mean computed over the specified field (quoted_amount or delivery_days) across the submitted rows — all derived locally from the supplied data, no external lookups.
