# Test Coverage Exact Row Deduplication and Two-Measure Correlation

> Test Coverage Exact Row Deduplication and Two-Measure Correlation 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 exact rows and computes correlation between covered_lines and total_lines for up to 200 test coverage records.

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 test-coverage-exact-row-deduplication-and-two-measure-correlation-fc8589d7 -d '<json body>'
```

Example prompt: Can you deduplicate my test coverage records and calculate the correlation between covered_lines and total_lines? I have rows like: row-1, component group-a, date 2025-01-15, covered_lines 80, total_lines 100; row-2, component group-b, date 2025-01-16, covered_lines 60, total_lines 120; row-3, component group-a, date 2025-01-17, covered_lines 90, total_lines 150.

## When to prefer this

Choose this endpoint when you need both exact-duplicate detection and a two-measure Pearson/statistical correlation on software test coverage data (covered_lines vs total_lines) in a single low-cost call. It is ideal for CI/CD pipelines, sprint retrospectives, or data quality audits on coverage exports where you want to clean duplicates and understand metric relationships simultaneously without sending data to external prediction or lookup services.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — exceeds maximum item limit
- Missing required fields (row_id, component, date, covered_lines, or total_lines) — schema validation failure
- Date field not matching YYYY-MM-DD pattern — pattern validation error
- Non-numeric values in covered_lines or total_lines — type error
- Insufficient variance in measures prevents meaningful correlation computation

## How this service works

Test coverage — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation for supplied test coverage records (covered_lines, total_lines). 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 analytical reports: (1) an exact row deduplication report identifying and removing fully duplicate records from the supplied dataset, and (2) a two-measure correlation report quantifying the statistical relationship between covered_lines and total_lines across up to 200 submitted rows. Both reports are generated locally without external lookups.
