# Account Research Coverage — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Account Research Coverage — Two-Measure Correlation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes Pearson correlation between researched_accounts and target_accounts, plus a weighted mean for a selected secondary measure, across up to 200 account research 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 account-research-coverage-two-measure-correlation-secondary-measure-0a9e4a29 -d '<json body>'
```

Example prompt: Run a two-report analysis on my account research coverage data — compute the Pearson correlation between researched_accounts and target_accounts, and also get the weighted mean for researched_accounts — across these 4 rows: row-1 group-a 2026-10-01 target=1 researched=10, row-2 group-b 2026-10-02 target=2 researched=20, row-3 group-a 2026-10-03 target=3 researched=15, row-4 group-b 2026-10-04 target=4 researched=30.

## When to prefer this

Choose this endpoint when you have up to 200 account research coverage records and need exactly two statistical outputs — a correlation and a weighted mean — computed purely on your supplied data with no external API calls or enrichment. Ideal for sales ops teams doing fast in-place analytics on researched vs target account counts without needing a full BI platform.

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows supplied — maxItems limit exceeded
- Missing required fields (row_id, company_group, date, researched_accounts, target_accounts) cause validation errors
- Invalid date format (must be YYYY-MM-DD pattern)
- Null values for both measures in a row may reduce statistical validity
- field enum value not matching 'researched_accounts' or 'target_accounts' causes rejection

## How this service works

Account research coverage — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied account research coverage records (researched_accounts, target_accounts). 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 Pearson correlation coefficient measuring the linear relationship between researched_accounts and target_accounts across all supplied rows, and (2) a weighted mean for the selected secondary measure (researched_accounts or target_accounts). Results are computed locally on the supplied data with no external lookups or predictions.
