# Feature Availability — Record Quality Audit + Numeric Interval Filter

> Feature Availability — Record Quality Audit + Numeric 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 2026-10-19).

Runs two local analytical reports on feature availability records: a record quality audit and a numeric interval filter for populated_features or expected_features fields, covering 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 feature-availability-record-quality-audit-numeric-interval-filter-799ae210 -d '<json body>'
```

Example prompt: Can you run a record quality audit and numeric interval filter on my feature availability data — I have rows with row_id, dataset_group, date, populated_features, and expected_features, and I want to filter on the populated_features field between 0 and 100, up to 200 rows?

## When to prefer this

Choose this endpoint when you need two simultaneous analytical passes on feature availability data — a quality audit and a numeric interval filter — within a single low-cost ($0.01 USDC) call, without requiring any external lookups or live data sources. Ideal for batch data pipeline validation, ML feature store QA, or dataset completeness checks where the data is already available locally.

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — exceeds row limit
- Missing required fields (row_id, date, populated_features, expected_features) — validation error
- Date field not in YYYY-MM-DD format — schema rejection
- Minimum value greater than maximum value — ambiguous interval
- Null values in numeric fields may affect interval filter results

## How this service works

Feature availability — Record quality audit + Numeric interval filter: Record quality audit + 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

Returns two independent analytical reports: (1) a record quality audit highlighting data issues in the supplied feature availability rows, and (2) a numeric interval filter report showing which rows fall within the specified minimum/maximum range for the chosen field (populated_features or expected_features). Results are based entirely on the supplied data with no external lookups.
