# Commercial Proposal Comparisons — IQR Outlier Flags + Two-Measure Correlation

> Commercial Proposal Comparisons — IQR Outlier Flags + 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).

Runs IQR-based outlier detection and two-measure correlation analysis on supplied commercial proposal data (quoted_amount, delivery_days) for 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 commercial-proposal-comparisons-iqr-outlier-flags-two-measure-0990b5f5 -d '<json body>'
```

Example prompt: I have a set of commercial proposals from multiple vendors — can you run IQR outlier detection and a two-measure correlation between quoted_amount and delivery_days on these rows? Here's the data: row-1, group-a, 2026-10-01, $10,000, 14 days; row-2, group-b, 2026-10-02, $95,000, 3 days; row-3, group-a, 2026-10-03, $12,000, 13 days.

## When to prefer this

Choose this endpoint when you need both IQR-based outlier detection and two-measure correlation on commercial proposal data in a single call at low cost ($0.01 USDC for both reports). Ideal for procurement teams comparing vendor bids across quoted price and delivery time dimensions with up to 200 rows, without needing live external data or predictive modeling.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds limit, request rejected
- Missing required fields (row_id, quoted_amount, delivery_days) — validation error
- Date field not matching YYYY-MM-DD pattern — schema validation failure
- All values null for a measure — correlation or IQR computation may be undefined
- Payment not completed — endpoint returns 402 without processing

## How this service works

Commercial proposal comparisons — IQR outlier flags + Two-measure correlation: IQR outlier flags + 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

Two analytical reports: (1) IQR outlier flags identifying which rows have quoted_amount or delivery_days values outside the interquartile range bounds, and (2) a two-measure correlation result showing the statistical relationship between quoted_amount and delivery_days across all supplied rows.
