# Commercial Proposal Comparisons — Numeric Distribution + Trailing Mean Series

> Commercial Proposal Comparisons — Numeric Distribution + Trailing Mean Series 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).

Computes a numeric distribution report and a trailing mean time series for quoted_amount or delivery_days across commercial proposal comparison records, grouped by company.

## 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-distribution-trailing-mean-4a3adc75 -d '<json body>'
```

Example prompt: I have 4 vendor proposals — group-a quoted $10 on 2026-10-01 with 1 delivery day, group-b quoted $20 on 2026-10-02 with 2 days, group-a quoted $15 on 2026-10-03 with 3 days, and group-b quoted $30 on 2026-10-04 with 4 days. Run a numeric distribution and trailing mean series on quoted_amount with a window of 2 so I can compare the vendors.

## When to prefer this

Choose this endpoint when you need both a numeric distribution and a trailing mean time series on commercial proposal data (quoted amounts or delivery days) in a single low-cost call. It is purpose-built for procurement and vendor comparison analytics on tabular row data up to 200 records. Prefer it over general analytics APIs when your data is already structured in the required schema and you want two complementary statistical views — distribution shape plus time-trend — without building custom pipelines.

## Known failure modes

- Fewer than 1 row provided — request rejected
- More than 200 rows submitted — exceeds maximum row limit
- Invalid date format (must be YYYY-MM-DD) — schema validation error
- Field value not in enum ['quoted_amount', 'delivery_days'] — rejected
- Window size outside range 2–200 — schema validation error
- Null values in quoted_amount or delivery_days may affect statistical completeness
- Payment of 0.01 USDC not provided or x402 protocol error — request blocked

## How this service works

Commercial proposal comparisons — Numeric distribution + Trailing mean series: Numeric distribution + Trailing mean series 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 sharing the same input data: (1) a numeric distribution breakdown of the selected field (quoted_amount or delivery_days) showing spread, frequency, and statistical shape; and (2) a trailing mean time series computed over the specified window size, grouped by company_group and ordered by date. Both reports are computed locally without external lookups. Up to 200 rows per call.
