# Third Party Reviews — Secondary-Measure Weighted Mean + Explicit Missing-Value Fill

> Third Party Reviews — Secondary-Measure Weighted Mean + Explicit Missing-Value Fill 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).

Computes a secondary-measure weighted mean and fills missing values in third-party review datasets (vendors_reviewed, outstanding_actions) for up to 200 rows, producing 2 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 third-party-reviews-secondary-measure-weighted-mean-explicit-missing-5589f689 -d '<json body>'
```

Example prompt: I have up to 200 rows of third-party vendor review records with vendors_reviewed and outstanding_actions columns — can you compute a secondary-measure weighted mean on the vendors_reviewed field and fill any missing values using median imputation?

## When to prefer this

Choose this endpoint when you have structured third-party review records with vendors_reviewed and/or outstanding_actions metrics, need both a weighted mean aggregation and explicit missing-value imputation in a single low-cost call ($0.01 USDC), and want offline/local computation without any live data lookup or external API dependency. Ideal for batches up to 200 rows where you need two reports at once.

## Known failure modes

- More than 200 rows submitted — request rejected with row limit error
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Missing required fields (row_id, control_group, date) — validation failure
- Field enum value not in ['vendors_reviewed','outstanding_actions'] — rejected
- Method enum not in ['zero','mean','median'] — rejected
- Empty rows array — minimum 1 item validation error

## How this service works

Third party reviews — Secondary-measure weighted mean + Explicit missing-value fill: Secondary-measure weighted mean + Explicit missing-value fill for supplied third party reviews records (vendors_reviewed, outstanding_actions). 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 2 analytical reports containing: secondary-measure weighted mean computations for the selected field (vendors_reviewed or outstanding_actions) across control groups, and an explicit missing-value-filled version of the dataset using the chosen method (zero, mean, or median). Results are computed locally with no external lookups.
