# Feature Availability Analytics — Numeric Distribution & Interval Filter

> Feature Availability Analytics — Numeric Distribution & Interval Filter 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 a numeric distribution and numeric interval filter report for up to 200 feature availability records (populated_features, expected_features), returning 2 analytical reports per call.

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 feature-availability-analytics-numeric-distribution-interval-filter-5aaabee9 -d '<json body>'
```

Example prompt: Analyze the distribution of populated_features in my dataset and filter results between 5 and 50 — here are up to 200 rows with row_id, date, dataset_group, populated_features, and expected_features values. Give me the numeric distribution and interval filter reports.

## When to prefer this

Choose this endpoint when you have up to 200 pre-loaded feature availability records and need both a distribution breakdown and an interval-filtered subset in a single paid call. It is ideal for lightweight, local analytical computation on feature completeness data without needing an external BI tool, database query engine, or live data connection. At $0.01 USDC for two reports, it is cost-effective for small-to-medium batch analytics on ML pipeline or data quality metrics.

## Known failure modes

- Input array is empty or exceeds 200 rows — validation error returned
- Invalid date format in any row (must be YYYY-MM-DD) — schema validation failure
- minimum value greater than maximum value — may return empty interval filter results
- Null values in populated_features or expected_features may be excluded from distribution calculations
- Payment of 0.01 USDC not completed — 402 Payment Required response

## How this service works

Feature availability — Numeric distribution + Numeric interval filter: Numeric distribution + Numeric interval filter 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

Two analytical reports: (1) a numeric distribution summarizing how values of the selected field (populated_features or expected_features) are spread across the supplied rows, and (2) an interval filter report identifying which of the up to 200 rows fall within the specified minimum–maximum numeric range.
