# Commercial Proposal Comparisons — Numeric Row Ordering + Equal-Width Histogram

> Commercial Proposal Comparisons — Numeric Row Ordering + Equal-Width Histogram 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 commercial proposal records by generating two local statistical reports: a numeric row ordering and an equal-width histogram for quoted_amount or delivery_days fields.

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-numeric-row-ordering-equal-width-3ce2b7ba -d '<json body>'
```

Example prompt: I have 8 vendor proposals with row IDs, company groups, dates, quoted amounts, and delivery days — can you rank them by quoted_amount and also show me an equal-width histogram with 5 bins so I can see how the prices are distributed?

## When to prefer this

Choose this endpoint when you have a structured dataset of commercial proposals (up to 200 rows) and need both a ranked ordering and a histogram distribution report on quoted_amount or delivery_days in a single call, without needing external data lookups, predictions, or professional assessments. It is ideal for procurement workflows where you want fast, reproducible statistical summaries of vendor bids at minimal cost ($0.01 USDC for both reports).

## Known failure modes

- Rows array empty or missing required fields (row_id, company_group, date, quoted_amount, delivery_days) returns validation error
- More than 200 rows submitted exceeds maximum and is rejected
- Bins value outside 1–30 range returns schema validation error
- All values null for the chosen field produces degenerate histogram
- Malformed date strings not matching YYYY-MM-DD pattern cause rejection
- Payment of 0.01 USDC not included results in 402 Payment Required

## How this service works

Commercial proposal comparisons — Numeric row ordering + Equal-width histogram: Numeric row ordering + Equal-width histogram 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 computed locally from the supplied rows: (1) a numeric row ordering that ranks all submitted proposal records by the chosen field (quoted_amount or delivery_days), and (2) an equal-width histogram showing frequency distribution across up to 30 configurable bins — all derived purely from the supplied data with no external lookups.
