## 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-grouped-numeric-summary-trailing-mean-429d1660 -d '<json body>'
```

Example prompt: I have a batch of commercial proposals from two supplier groups — group-a and group-b — with quoted amounts and delivery days across 10 dates. Can you run a grouped numeric summary and a trailing mean series with a window of 3 on the quoted_amount field?

## When to prefer this

Choose this endpoint when you need both a grouped statistical summary AND a rolling mean series in a single call for commercial proposal data with quoted amounts and delivery days. Ideal for procurement analytics, vendor benchmarking, or bid evaluation workflows where you have up to 200 rows and want two complementary reports at minimal cost ($0.01 USDC). Not suitable if you need prediction, live market data, or more than 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Null values in the numeric field may affect summary and trailing mean calculations
- Window size larger than the number of data points yields incomplete or no trailing mean values
- Missing required fields (row_id, company_group, date) cause row rejection

## How this service works

Commercial proposal comparisons — Grouped numeric summary + Trailing mean series: Grouped numeric summary + 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: (1) a grouped numeric summary breaking down quoted_amount or delivery_days statistics by company_group, and (2) a trailing (rolling) mean series over the specified window for the chosen field — all computed locally from the supplied rows with no external lookups.
