# Feature Availability Analytics — Numeric Row Ordering + Keyed Dataset Comparison

> Feature Availability Analytics — Numeric Row Ordering + 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).

Runs two local analytical reports on feature availability data: numeric row ordering and keyed dataset comparison across up to 200 rows of populated_features and expected_features.

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-row-ordering-keyed-dataset-48c8c64a -d '<json body>'
```

Example prompt: Rank these feature availability rows by populated_features and compare them against a second dataset keyed by row_id and dataset_group — here are up to 200 rows with date, populated_features, and expected_features for each.

## When to prefer this

Choose this endpoint when you need both a ranked ordering of feature availability rows AND a side-by-side keyed comparison of two datasets in a single call, without needing live data lookups or external predictions. It is best suited for batch data quality audits, ETL pipeline monitoring, and feature coverage tracking where you already have the data and want structured analytical outputs at low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — request rejected with validation error
- Missing required fields (row_id, dataset_group, date, populated_features, expected_features) cause row-level errors
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Null values in numeric fields may be excluded from ordering calculations
- Mismatched row_ids between primary and secondary datasets result in unmatched rows in comparison report
- Payment not provided or insufficient USDC causes 402 rejection

## How this service works

Feature availability — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + 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 row ordering of the input records sorted by the selected field (populated_features or expected_features), and (2) a keyed dataset comparison report identifying differences between the primary and secondary datasets matched by row_id and dataset_group. All computation is local with no external lookups.
