# Proposal Preparation — Numeric Distribution + Secondary-Measure Weighted Mean

> Proposal Preparation — Numeric Distribution + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes a numeric distribution report and a secondary-measure weighted mean for proposal preparation records (completed_sections, planned_sections) over 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 proposal-preparation-numeric-distribution-secondary-measure-weighted-7158edb1 -d '<json body>'
```

Example prompt: Run a numeric distribution and weighted mean analysis on my proposal preparation data — I have 4 records with row IDs row-1 through row-4, dates from 2026-10-01 to 2026-10-04, document groups group-a and group-b, completed_sections values of 10, 20, 15, 30, and planned_sections of 1, 2, 3, 4. Use completed_sections as the primary field.

## When to prefer this

Choose this endpoint when you need both a numeric distribution and a weighted mean computed together from proposal preparation records in a single low-cost call ($0.01 USDC for both reports). It is best for offline/batch statistical summarization of section-tracking data without needing live lookup, prediction, or external enrichment. Prefer it over generic analytics tools when your data fits the proposal preparation schema (completed_sections, planned_sections, document_group, date) and you want two complementary statistical views in one response.

## Known failure modes

- Fewer than 1 row submitted — returns validation error
- More than 200 rows submitted — rejected, exceeds maximum
- Invalid date format (not YYYY-MM-DD) — row rejected or error returned
- Null values in both measure fields for a row — may be excluded from weighted mean
- Missing required fields (row_id) — validation error
- Field enum value not in [completed_sections, planned_sections] — schema validation failure

## How this service works

Proposal preparation — Numeric distribution + Secondary-measure weighted mean: Numeric distribution + Secondary-measure weighted mean 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) across the supplied rows, and (2) a weighted mean where the secondary measure serves as weights — both computed locally from the supplied data with no external lookups, covering up to 200 rows.
