# Proposal Preparation — Duplicate Key Report + Category Frequencies

> Proposal Preparation — Duplicate Key Report + Category Frequencies is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Analyzes proposal preparation records to produce a duplicate key report and category frequency breakdown for up to 200 rows using local analytical engines.

## 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-category-frequencies-de413a8f -d '<json body>'
```

Example prompt: Can you check my proposal preparation records for duplicate row IDs and tell me how often each document group appears? I have rows with fields like row_id, document_group, date, completed_sections, and planned_sections — up to 200 rows total.

## When to prefer this

Choose this endpoint when you need to simultaneously audit a batch of proposal preparation records for duplicate row identifiers AND understand the distribution of document groups — all in a single low-cost call ($0.01 USDC for both reports). Ideal for data quality checks before ingesting or reporting on proposal datasets of up to 200 rows, without needing any live lookup or external enrichment.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems limit
- Missing required fields (row_id, date, completed_sections, planned_sections) — validation error
- Invalid date format (must be YYYY-MM-DD) — schema validation failure
- Empty rows array — rejected due to minItems constraint
- Malformed numeric values for completed_sections or planned_sections outside allowed range

## How this service works

Proposal preparation — Duplicate key report + Category frequencies: Duplicate key report + Category frequencies 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 analytical reports: (1) a duplicate key report identifying any repeated row_id values within the submitted records, and (2) a category frequency table showing how often each document_group value appears across the rows. No external data is fetched; all analysis is performed locally on the supplied rows.
