# Commercial Proposal Comparisons — Duplicate Key Report + Two-Measure Correlation

> Commercial Proposal Comparisons — 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 2026-10-17).

Analyzes up to 200 rows of commercial proposal comparison records to produce a duplicate key report and a two-measure correlation analysis between quoted_amount and delivery_days.

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 commercial-proposal-comparisons-duplicate-key-report-two-measure-33ab4ea4 -d '<json body>'
```

Example prompt: Can you check my vendor bid data for duplicate row IDs and also run a correlation between quoted_amount and delivery_days? I have 4 proposals: row-1 from group-a on 2026-10-01 for $10 with 1 delivery day, row-2 from group-b on 2026-10-02 for $20 with 2 days, row-3 from group-a on 2026-10-03 for $15 with 3 days, and row-4 from group-b on 2026-10-04 for $30 with 4 days.

## When to prefer this

Choose this endpoint when you have tabular commercial proposal or vendor bid data and need both a data-integrity check (duplicate key detection) and a statistical relationship measure (correlation) between quoted_amount and delivery_days in a single low-cost call. It operates entirely on supplied data with no external lookups, making it fast, deterministic, and privacy-safe. Best suited for procurement analytics, RFP response auditing, or supplier comparison workflows with up to 200 rows.

## Known failure modes

- Fewer than 1 row submitted — minimum input validation error
- More than 200 rows submitted — exceeds max item limit
- Missing required fields (row_id, company_group, date, quoted_amount, delivery_days) — schema validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Numeric values outside allowed range (±1,000,000,000,000) — range validation error
- Insufficient numeric variance in quoted_amount or delivery_days for meaningful correlation — may return degenerate correlation result

## How this service works

Commercial proposal comparisons — Duplicate key report + Two-measure correlation: Duplicate key report + Two-measure correlation 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 independent analytical reports: (1) a duplicate key report identifying any rows with repeated row_id values within the supplied dataset, and (2) a two-measure correlation report quantifying the statistical relationship between quoted_amount and delivery_days across all supplied rows. No external data sources or predictions are used.
