# Wallet Inventory Two-Measure Correlation and Keyed Dataset Comparison

> Wallet Inventory Two-Measure Correlation and Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Computes Pearson/rank correlation between token_units and reference_price, and compares two keyed wallet inventory datasets row-by-row, returning two analytical reports for up to 200 rows each.

## 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 wallet-inventory-two-measure-correlation-and-keyed-dataset-comparison-c2378941 -d '<json body>'
```

Example prompt: Can you run a correlation analysis between token_units and reference_price on my wallet inventory, and also compare it against a second dataset to spot differences? I have two sets of up to 200 rows with fields like row_id, instrument_group, date, token_units, and reference_price.

## When to prefer this

Choose this endpoint when you need both a correlation analysis between two numeric wallet metrics AND a keyed row-level comparison between two dataset versions in a single API call, without requiring live market data or external lookups. It is ideal for offline portfolio audits, snapshot diffing, and statistical validation of wallet records at low cost ($0.01 for both reports).

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required fields (row_id, instrument_group, date, token_units, reference_price) cause validation errors
- Null values in token_units or reference_price may reduce correlation sample size
- Date strings not matching YYYY-MM-DD pattern will fail schema validation
- Mismatched row_ids between primary and secondary datasets may produce incomplete comparison
- Fewer than 2 valid numeric rows may prevent meaningful correlation computation

## How this service works

Wallet inventory — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + Keyed dataset comparison for supplied wallet inventory records (token_units, reference_price). 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) a two-measure correlation result quantifying the statistical relationship between token_units and reference_price across the supplied rows, and (2) a keyed dataset comparison report highlighting row-level differences between the primary and secondary inventory datasets, both computed locally with no external lookups.
