# Proposal Preparation Duplicate Key Report + Equal-Width Histogram

> Proposal Preparation Duplicate Key Report + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Generates two local analytical reports — a duplicate key report and an equal-width histogram — for proposal preparation records containing completed_sections and planned_sections fields.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-duplicate-key-report-equal-width-histogram-26147a44 -d '<json body>'
```

Example prompt: Check my proposal preparation records for duplicate row IDs and also generate a 10-bin histogram for the completed_sections field — here are 50 rows with row_id, document_group, date, completed_sections, and planned_sections.

## When to prefer this

Choose this endpoint when you need both a duplicate key detection report AND a histogram for proposal preparation data in a single $0.01 call. It is ideal for offline or local analytical use cases where no external lookup, live data, or prediction is required. Prefer it over separate histogram or duplicate-check endpoints when working specifically with completed_sections and planned_sections fields and you want to save cost by combining two reports in one request.

## Known failure modes

- Exceeds 200 row limit — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- bins value outside 1–30 range — validation error
- Missing required fields (row_id, document_group, date) — schema validation error
- Numeric values outside ±1,000,000,000,000 range — validation error
- Empty rows array — minimum items constraint violation

## How this service works

Proposal preparation — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 independent reports: (1) a duplicate key report listing any row_ids or document_groups that appear more than once, and (2) an equal-width histogram showing the frequency distribution of values in the selected field (completed_sections or planned_sections) divided into the specified number of bins (1–30). Up to 200 input rows processed per call.
