# Release Note Coverage — Exact Row Deduplication + Numeric Distribution

> Release Note Coverage — Exact Row Deduplication + Numeric Distribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Deduplicates release note coverage rows and computes numeric distribution statistics for documented_changes and released_changes fields across up to 200 supplied records.

## 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 release-note-coverage-exact-row-deduplication-numeric-distribution-ed941df9 -d '<json body>'
```

Example prompt: Can you deduplicate my release note coverage records and show me the numeric distribution of documented_changes? I have 4 rows: row-1 on 2026-10-01 in group-a with released_changes=1 and documented_changes=10, row-2 on 2026-10-02 in group-b with released=2 documented=20, row-3 on 2026-10-03 in group-a with released=3 documented=15, and row-4 on 2026-10-04 in group-b with released=4 documented=30.

## When to prefer this

Choose this endpoint when you need to simultaneously audit a release note coverage dataset for exact duplicate rows AND obtain a numeric distribution summary of either the documented_changes or released_changes field — all in a single low-cost call. Ideal for data quality checks on release tracking datasets before reporting or aggregation. Not suitable if you need live data retrieval, predictions, external enrichment, or analysis of fields beyond the two supported numeric columns.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, date, document_group) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema validation failure
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — rejected
- Empty rows array — minItems:1 constraint triggers error
- Invalid field enum value other than 'documented_changes' or 'released_changes' — schema rejection

## How this service works

Release note coverage — Exact row deduplication + Numeric distribution: Exact row deduplication + Numeric distribution for supplied release note coverage records (documented_changes, released_changes). 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) an exact row deduplication report identifying which of the supplied rows are exact duplicates, and (2) a numeric distribution report for the selected field (documented_changes or released_changes), covering statistical spread metrics across the supplied records. Both reports are computed locally with no external lookups.
