# Proposal Preparation Grouped Numeric Summary and Numeric Row Ordering

> Proposal Preparation Grouped Numeric Summary and Numeric Row Ordering is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Generates two analytical reports for proposal preparation records: a grouped numeric summary and a numeric row ordering, based on completed_sections and planned_sections fields.

## 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 proposal-preparation-grouped-numeric-summary-and-numeric-row-ordering-510a1a53 -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and row ordering on these proposal records for me? I have 4 rows across two document groups — group-a and group-b — with dates from 2026-10-01 to 2026-10-04, and I want the analysis based on the completed_sections field.

## When to prefer this

Choose this endpoint when you have a batch of proposal preparation records (up to 200 rows) and need both a grouped aggregate summary and a numerically ordered ranking of rows in a single API call for a flat fee of $0.01 USDC. It is ideal for offline/local analytical processing of user-supplied data without requiring any external data sources, live lookups, or predictions.

## Known failure modes

- Missing required fields (row_id, date, document_group) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows exceeds the maximum and triggers an error
- Numeric values outside the allowed range (±1,000,000,000,000) are rejected
- Empty rows array is not permitted (minItems: 1)
- Invalid field enum value (anything other than completed_sections or planned_sections) returns an error

## How this service works

Proposal preparation — Grouped numeric summary + Numeric row ordering: Grouped numeric summary + Numeric row ordering for supplied proposal preparation records (completed_sections, planned_sections). 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 derived from the supplied proposal preparation rows: (1) a grouped numeric summary aggregating completed_sections or planned_sections values by document_group, and (2) a numeric row ordering ranking each row by the selected numeric field. All analysis is performed locally on the submitted data with no external lookups.
