# Commercial Proposal Comparisons — Base-100 Series + Equal-Width Histogram

> Commercial Proposal Comparisons — Base-100 Series + 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).

Generates two analytical reports — a Base-100 indexed series and an equal-width histogram — over supplied commercial proposal comparison data (quoted_amount, delivery_days) for up to 200 rows.

## 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-base-100-series-equal-width-histogram-012598ff -d '<json body>'
```

Example prompt: I have 8 supplier proposals — can you run a Base-100 series indexed to the first row and a 10-bin equal-width histogram on the quoted_amount field? Here are the rows: row-1 group-a 2026-01-10 $5000 14 days, row-2 group-b 2026-01-11 $4800 12 days, row-3 group-a 2026-01-12 $5300 16 days, row-4 group-b 2026-01-13 $4600 11 days, row-5 group-a 2026-01-14 $5100 15 days, row-6 group-c 2026-01-15 $4900 13 days, row-7 group-c 2026-01-16 $5200 14 days, row-8 group-b 2026-01-17 $4700 12 days.

## When to prefer this

Choose this endpoint when you need two complementary analytical views — a normalized Base-100 trend series and a frequency histogram — on commercial proposal data (quoted amounts or delivery days) from multiple vendors or company groups, all computed locally without any external lookups. Ideal for procurement analytics, RFP evaluation, or supplier benchmarking workflows where you supply up to 200 rows and want fast, deterministic statistical summaries at minimal cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required row fields (row_id, company_group, date, quoted_amount, delivery_days) — validation error
- base_index out of range for the number of rows provided — error
- bins value outside 1–30 range — validation error
- date field not matching YYYY-MM-DD pattern — parsing error
- All values for the selected field are null — cannot compute series or histogram
- Payment not included or insufficient — 402 payment required

## How this service works

Commercial proposal comparisons — Base-100 series + Equal-width histogram: Base-100 series + 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

Returns two analytical reports: (1) a Base-100 indexed series showing each row's field value normalized relative to the designated base row, and (2) an equal-width histogram dividing the field's value range into the specified number of bins with frequency counts per bin. Both reports operate on the same supplied dataset of up to 200 commercial proposal rows.
