# Document Retrieval Analytics — Exact Row Deduplication + Two-Measure Correlation

> Document Retrieval Analytics — Exact Row Deduplication + 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 2026-10-26).

Deduplicates up to 200 document retrieval records and computes a correlation analysis between retrieved_bytes and request_ms, returning two independent analytical reports.

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 document-retrieval-analytics-exact-row-deduplication-two-measure-ca0d5f0f -d '<json body>'
```

Example prompt: I have 150 document retrieval log rows with fields row_id, site_group, date, retrieved_bytes, and request_ms — can you deduplicate exact duplicate rows and run a correlation analysis between retrieved_bytes and request_ms, giving me two separate reports?

## When to prefer this

Choose this endpoint when you have a batch of up to 200 document retrieval records and need both exact deduplication and a two-measure Pearson/statistical correlation between retrieved_bytes and request_ms in a single $0.01 call. Prefer it over general-purpose analytics tools when you want a lightweight, local-engine computation without live data lookup or external integrations. Ideal for periodic QA passes on retrieval logs or performance audits.

## Known failure modes

- Submitting more than 200 rows will be rejected (maxItems constraint)
- Missing required fields (row_id, site_group, date, retrieved_bytes, request_ms) will cause validation errors
- Malformed date strings not matching YYYY-MM-DD pattern will fail schema validation
- Null values in both numeric measures may reduce correlation reliability
- Empty row array (minItems:1 not satisfied) will fail
- Payment failure or insufficient USDC balance will block the call

## How this service works

Document retrieval — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation for supplied document retrieval records (retrieved_bytes, request_ms). 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) a deduplicated version of the submitted rows with exact duplicate records removed, and (2) a two-measure correlation analysis quantifying the statistical relationship between retrieved_bytes and request_ms across the cleaned dataset.
