# Metadata Completeness — Exact Row Deduplication + Keyed Dataset Comparison

> Metadata Completeness — Exact Row Deduplication + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Deduplicates rows and compares two keyed metadata completeness datasets (present_fields vs expected_fields) for up to 200 rows, returning 2 analytical reports.

## 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 metadata-completeness-exact-row-deduplication-keyed-dataset-comparison-18c3a8a7 -d '<json body>'
```

Example prompt: Can you deduplicate my metadata completeness records and compare them against a second dataset? I have two sets of up to 200 rows, each with row_id, site_group, date, present_fields, and expected_fields — I want both the deduplication report and the keyed comparison report showing where the field counts differ.

## When to prefer this

Choose this endpoint when you need both exact duplicate row detection and a side-by-side keyed comparison of two metadata completeness datasets (present_fields vs expected_fields) in a single $0.01 call. It is ideal for data quality workflows where you have two versions of a metadata inventory and want to reconcile them without setting up a local analytics environment. Prefer it over generic deduplication tools when your data is structured around site_group, date, and field-count metrics specifically.

## Known failure modes

- Input exceeds 200 rows — request rejected with validation error
- Missing required fields (row_id, site_group, date, present_fields, expected_fields) — row rejected or error returned
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Numeric values outside allowed range (-1e12 to 1e12) — validation error
- Empty rows array (minItems: 1 not met) — request rejected
- Payment not included or insufficient — 402 Payment Required response

## How this service works

Metadata completeness — Exact row deduplication + Keyed dataset comparison: Exact row deduplication + Keyed dataset comparison for supplied metadata completeness records (present_fields, expected_fields). 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

Two analytical reports: (1) an exact row deduplication report identifying and removing duplicate records from the input rows, and (2) a keyed dataset comparison report matching rows across the two supplied datasets by key fields and highlighting differences in present_fields and expected_fields values. No external lookups or predictions are made; analysis is performed locally on the supplied data.
