# Feature Availability Numeric Distribution and IQR Outlier Flags

> Feature Availability Numeric Distribution and IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes numeric distribution statistics and IQR-based outlier flags for up to 200 feature availability records across two independent analytical reports.

## 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 feature-availability-numeric-distribution-and-iqr-outlier-flags-6c5d9850 -d '<json body>'
```

Example prompt: Can you run a numeric distribution analysis and IQR outlier detection on my feature availability data? I have rows with populated_features and expected_features counts across two dataset groups from October 2026 — up to 200 rows — and I want both reports using the populated_features field.

## When to prefer this

Choose this endpoint when you have up to 200 feature availability records and need both a numeric distribution summary and IQR-based outlier detection in a single call for $0.01 USDC. It is ideal for lightweight, offline statistical profiling of dataset quality metrics without requiring a live data connection or external ML infrastructure. Prefer it over general-purpose analytics APIs when your input fits the structured row schema with populated_features and expected_features fields and you need two bundled reports cheaply.

## Known failure modes

- Fewer than 1 row supplied returns an error
- More than 200 rows causes rejection — batch must be split
- Invalid date format (not YYYY-MM-DD) fails schema validation
- Null values in the selected field may reduce report coverage or skew distribution
- Missing required fields (row_id, date, populated_features, expected_features) cause validation failure
- Payment not attached or insufficient USDC causes 402 rejection

## How this service works

Feature availability — Numeric distribution + IQR outlier flags: Numeric distribution + IQR outlier flags for supplied feature availability records (populated_features, expected_features). 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 numeric distribution profile (e.g. min, max, mean, median, quartiles, std dev) and (2) IQR-based outlier flags per row for the selected field (populated_features or expected_features), covering up to 200 supplied rows.
