# Join Coverage Exact Row Deduplication and Duplicate Key Report

> Join Coverage Exact Row Deduplication and Duplicate Key Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Deduplicates up to 200 join coverage records by exact row and produces a duplicate key report across matched_rows and source_rows 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 join-coverage-exact-row-deduplication-and-duplicate-key-report-d2c0c08e -d '<json body>'
```

Example prompt: I have a set of join coverage records with row_id, date, dataset_group, matched_rows, and source_rows — can you run exact row deduplication and get me a duplicate key report for these rows: [{"row_id":"row-1","date":"2026-10-01","dataset_group":"group-a","matched_rows":10,"source_rows":1},{"row_id":"row-2","date":"2026-10-02","dataset_group":"group-b","matched_rows":20,"source_rows":2}]?

## When to prefer this

Choose this endpoint when you have up to 200 join coverage records (with matched_rows and source_rows fields) and need both exact row deduplication and a duplicate key report in a single low-cost call. Prefer this over general-purpose deduplication tools when your data specifically follows the join coverage schema (row_id, dataset_group, date, matched_rows, source_rows). It is ideal for data quality checks before merging, auditing ETL pipeline outputs, or validating join completeness metrics.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, dataset_group, date, matched_rows, source_rows) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Numeric values outside allowed range (-1e12 to 1e12) — schema rejection
- Empty rows array — minItems:1 constraint violation
- Payment not included or insufficient — x402 payment required error

## How this service works

Join coverage — Exact row deduplication + Duplicate key report: Exact row deduplication + Duplicate key report for supplied join coverage records (matched_rows, source_rows). 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 for the supplied join coverage rows: (1) an exact row deduplication report identifying and removing fully identical rows, and (2) a duplicate key report flagging records sharing the same key fields across matched_rows and source_rows. Both reports are computed locally on the supplied data with no external lookups.
