# Feature Availability Analytics — Record Quality Audit, Exact Row Deduplication & Equal-Width Histogram

> Feature Availability Analytics — Record Quality Audit, Exact Row Deduplication & Equal-Width Histogram 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 three independent analytical reports (record quality audit, exact row deduplication, and equal-width histogram) on supplied feature availability records containing populated_features and expected_features fields, for up to 200 rows.

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-record-quality-audit-exact-row-a7720f66 -d '<json body>'
```

Example prompt: Can you run a record quality audit, exact deduplication check, and a 10-bin histogram on my feature availability data — I have rows for dataset groups 'group-a' and 'group-b' with populated_features and expected_features values, and I want the histogram over the populated_features field?

## When to prefer this

Choose this endpoint when you need to simultaneously audit data quality, remove exact duplicate rows, and understand the numeric distribution of feature availability records in a single paid call. It is ideal for ML feature store monitoring, dataset hygiene checks before model training, or periodic data pipeline validation — especially when you want three complementary analytical views for a flat $0.01 fee without any external API calls or live data lookups.

## Known failure modes

- More than 200 rows submitted — request rejected, reduce row count
- Missing required fields (row_id, date, populated_features, expected_features) — validation error returned
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- bins value outside 1–30 range — rejected with parameter error
- Numeric values outside allowed range (-1e12 to 1e12) — schema rejection
- Invalid field enum value (not populated_features or expected_features) — error response

## How this service works

Feature availability — Record quality audit + Exact row deduplication + Equal-width histogram: Record quality audit + Exact row deduplication + Equal-width histogram for supplied feature availability records (populated_features, expected_features). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent analytical reports: (1) a record quality audit highlighting null values, format issues, and completeness metrics; (2) an exact row deduplication report listing identical rows; and (3) an equal-width histogram of the specified numeric field (populated_features or expected_features) partitioned into up to 30 bins. All computed locally without external lookups or predictions.
