# Feature Availability Analytics — Numeric Distribution + Keyed Dataset Comparison

> Feature Availability Analytics — Numeric Distribution + Keyed Dataset Comparison 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 report and a keyed dataset comparison for up to 200 feature availability records (populated_features vs expected_features) using local analytical engines.

## 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-keyed-dataset-81eb6853 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and keyed dataset comparison on my feature availability data? I have two groups — 'group-a' and 'group-b' — with populated_features and expected_features values across October 2026, up to 200 rows, and I want to analyze the 'populated_features' field.

## When to prefer this

Choose this endpoint when you need both a numeric distribution analysis and a keyed group comparison for feature availability data in a single low-cost call ($0.01 USDC). It is ideal when you have structured records with populated_features and expected_features counts grouped by dataset_group and date, and you want local analytical computation without external API calls, predictions, or professional assessments. Prefer it over single-report endpoints when both distribution and comparison insights are needed simultaneously.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, dataset_group, date, populated_features, expected_features) cause schema validation failure
- Invalid date format (not YYYY-MM-DD) rejected by pattern validation
- Null values in both numeric fields may reduce statistical meaningfulness
- Fewer than 1 row in the array causes a minItems validation error
- Invalid field enum value (not 'populated_features' or 'expected_features') causes rejection

## How this service works

Feature availability — Numeric distribution + Keyed dataset comparison: Numeric distribution + Keyed dataset comparison 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 report summarizing statistical properties of the selected field (populated_features or expected_features) across the supplied rows, and (2) a keyed dataset comparison report contrasting the two metrics by dataset_group and date key. Both reports are computed locally without external lookups. Up to 200 rows processed per call.
