# Proposal Preparation Numeric Distribution and Date by Category Pivot

> Proposal Preparation Numeric Distribution and Date by Category Pivot 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).

Analyzes proposal preparation records by computing numeric distribution statistics and a date-by-category pivot table for 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-numeric-distribution-and-date-by-category-pivot-05f8eba8 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and date-by-category pivot on my proposal preparation data — I have rows with document groups like 'group-a' and 'group-b', dates, and counts for completed_sections and planned_sections? Analyze the completed_sections field.

## When to prefer this

Choose this endpoint when you need both a statistical numeric distribution and a date-segmented category pivot for proposal preparation data in a single low-cost call. It is purpose-built for proposal tracking fields (completed_sections, planned_sections) organized by document_group and date, and delivers two reports for $0.01 USDC without any external data lookups or prediction.

## Known failure modes

- Missing required fields (row_id, date, document_group) cause validation errors
- Date values not matching YYYY-MM-DD pattern are rejected
- Exceeding 200 rows results in a rejection or truncation
- Null numeric values may affect distribution statistics
- Invalid field enum value (not completed_sections or planned_sections) causes an error
- Empty rows array is rejected (minItems: 1)

## How this service works

Proposal preparation — Numeric distribution + Date by category pivot: Numeric distribution + Date by category pivot 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: (1) a numeric distribution of the selected field (completed_sections or planned_sections) showing statistical spread across the dataset, and (2) a date-by-category pivot table breaking down the field values by document_group over time. Both reports are generated locally from the supplied data with no external lookups.
