# Proposal Preparation — Exact Row Deduplication + Category Frequencies

> Proposal Preparation — Exact Row Deduplication + 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).

Deduplicates proposal preparation records exactly and computes category frequencies for completed_sections and planned_sections fields across up to 200 rows.

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-exact-row-deduplication-category-frequencies-2f445c0e -d '<json body>'
```

Example prompt: I have up to 200 rows of proposal preparation data with row IDs, document groups, dates, and counts of completed and planned sections — can you deduplicate the exact rows and give me a category frequency breakdown for both the completed_sections and planned_sections fields?

## When to prefer this

Choose this endpoint when you need both exact row deduplication and category frequency analysis on proposal preparation data in a single low-cost call. It is ideal for data quality checks on proposal tracking datasets with up to 200 rows containing completed_sections and planned_sections numeric fields. It is not suitable for fuzzy deduplication, live data lookups, predictions, or datasets exceeding 200 rows.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, document_group, date, completed_sections, planned_sections) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Numeric values outside allowed range (-1e12 to 1e12) — validation error
- Empty rows array — minimum items constraint violated
- Payment not included or insufficient — 402 payment required

## How this service works

Proposal preparation — Exact row deduplication + Category frequencies: Exact row deduplication + 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) an exact row deduplication report showing which rows are unique versus duplicates and the deduplicated dataset, and (2) a category frequency report showing how often each distinct value appears in the completed_sections and planned_sections columns across the supplied rows.
