# Registry Snapshots IQR Outlier Flags and Secondary-Measure Weighted Mean

> Registry Snapshots IQR Outlier Flags and 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 2026-10-23).

Analyzes registry snapshot rows for IQR-based outlier detection and computes a secondary-measure weighted mean, returning two independent analytical reports for up to 200 rows.

## 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 registry-snapshots-iqr-outlier-flags-and-secondary-measure-weighted-b6342a5a -d '<json body>'
```

Example prompt: I have 50 rows of registry snapshot data with registered_entities and changed_entities counts per company group and date — can you flag IQR outliers and compute the secondary-measure weighted mean on the registered_entities field for me?

## When to prefer this

Choose this endpoint when you have registry snapshot data (registered entities, changed entities) organized by company group and date, and need both IQR-based outlier flagging and a weighted mean in a single low-cost call. Ideal for data quality checks before reporting, anomaly detection in registration trends, and batch statistical analysis of up to 200 rows without needing an external data connection or live lookup.

## Known failure modes

- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, company_group, date, registered_entities, changed_entities) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Numeric values outside allowed range (-1T to 1T) cause validation errors
- Insufficient data variance may produce trivial or degenerate IQR results
- All-null values for the selected field may prevent meaningful computation

## How this service works

Registry snapshots — IQR outlier flags + Secondary-measure weighted mean: IQR outlier flags + Secondary-measure weighted mean for supplied registry snapshots records (registered_entities, changed_entities). 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) IQR outlier flags indicating which rows have values outside the interquartile range for the selected field, and (2) a secondary-measure weighted mean computed across the supplied rows. Results are based entirely on the supplied data with no external lookups.
