# Export Validation — Record Quality Audit + Two-Measure Correlation

> Export Validation — Record Quality Audit + 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 2026-10-15).

Runs a record quality audit and a two-measure correlation analysis on export validation rows (valid_rows vs exported_rows) for up to 200 supplied 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 export-validation-record-quality-audit-two-measure-correlation-6fd00d62 -d '<json body>'
```

Example prompt: Can you audit the quality of these export validation records and check whether valid_rows and exported_rows are correlated? I have 4 rows: row-1 on 2026-10-01 for group-a with valid_rows=10 and exported_rows=1, row-2 on 2026-10-02 for group-b with valid_rows=20 and exported_rows=2, row-3 on 2026-10-03 for group-a with valid_rows=15 and exported_rows=3, and row-4 on 2026-10-04 for group-b with valid_rows=30 and exported_rows=4.

## When to prefer this

Choose this endpoint when you need both a record quality audit and a correlation analysis on export validation data (valid_rows vs exported_rows) in a single paid call. Ideal for data engineering teams validating export pipeline outputs in batches up to 200 rows. Prefer this over single-analysis endpoints when you need two reports from one request to reduce cost and latency. Not suitable if you need live data lookup, predictions, external enrichment, or more than 200 rows.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum batch size
- Missing required fields (row_id, date, valid_rows, exported_rows, dataset_group) — validation error
- Date field not in YYYY-MM-DD format — schema validation failure
- row_id or dataset_group exceeds 80 character limit — rejected
- Numeric values outside allowed range — schema error
- Payment of 0.01 USDC not completed — 402 response

## How this service works

Export validation — Record quality audit + Two-measure correlation: Record quality audit + Two-measure correlation for supplied export validation records (valid_rows, exported_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

Two independent analytical reports: (1) a record quality audit identifying issues, nulls, or anomalies in the supplied rows, and (2) a two-measure correlation report quantifying the statistical relationship between valid_rows and exported_rows across the submitted dataset. Results are derived entirely from the supplied data using local analytical engines, with no external lookups or predictions.
