# Commercial Proposal Comparisons — Equal-Width Histogram + Explicit Missing-Value Fill

> Commercial Proposal Comparisons — Equal-Width Histogram + Explicit Missing-Value Fill 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).

Generates equal-width histogram and explicit missing-value fill reports for commercial proposal comparison data (quoted_amount, delivery_days) across up to 200 rows.

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-equal-width-histogram-explicit-a064237f -d '<json body>'
```

Example prompt: I have 150 commercial proposals with quoted_amount and delivery_days — can you run an equal-width histogram with 10 bins on quoted_amount and fill any missing values using median imputation? Here's the data as rows with row_id, company_group, and date fields.

## When to prefer this

Choose this endpoint when you need statistical distribution analysis (histogram) and missing-value imputation for commercial proposal or vendor bid datasets of up to 200 rows, and do not need live market data, predictive modeling, or external validation. Ideal for procurement analytics workflows where you want a bundled histogram + null-fill report at low cost ($0.01 USDC for both).

## Known failure modes

- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id) in one or more row objects
- Invalid date format (must match YYYY-MM-DD pattern)
- bins value outside allowed range of 1–30
- Numeric values outside allowed range (-1e12 to 1e12)
- Invalid enum value for field or method parameters

## How this service works

Commercial proposal comparisons — Equal-width histogram + Explicit missing-value fill: Equal-width histogram + Explicit missing-value fill 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) an equal-width histogram showing bin ranges and counts for the selected field (quoted_amount or delivery_days), and (2) an explicit missing-value fill report showing how null values were replaced using the chosen method (zero, mean, or median). Both reports are computed locally with no external lookups.
