# Null Coverage Analytics: Numeric Distribution + Interval Filter

> Null Coverage 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 2026-10-16).

Computes a numeric distribution and an interval-filtered report for null coverage data (missing_values, total_values) across up to 200 rows, returning 2 independent analytical reports.

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 null-coverage-analytics-numeric-distribution-interval-filter-73505830 -d '<json body>'
```

Example prompt: Analyze the distribution of missing_values in my null coverage data and filter to rows where missing_values is between 0 and 50 — here are my rows: row-1 (group-a, 2024-01-01, 10 missing out of 100), row-2 (group-b, 2024-01-02, 5 missing out of 80), row-3 (group-a, 2024-01-03, 45 missing out of 200).

## When to prefer this

Choose this endpoint when you have up to 200 null coverage records (with missing_values and total_values) and need both a distribution breakdown and an interval-filtered subset in a single low-cost call. Ideal for data quality pipelines, completeness audits, and monitoring workflows that need quick local analytics without external lookups or predictions.

## Known failure modes

- Missing required row fields (row_id, date, missing_values, total_values) causes validation failure
- Exceeding 200 rows in the input array returns an error
- Date values not matching YYYY-MM-DD pattern are rejected
- minimum greater than maximum causes undefined filter behavior
- Null values in the selected field may be excluded from distribution calculations

## How this service works

Null coverage — Numeric distribution + Numeric interval filter: Numeric distribution + Numeric interval filter for supplied null coverage records (missing_values, total_values). 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 2 independent analytical reports: (1) a numeric distribution summarizing the spread of the selected field (missing_values or total_values) across up to 200 input rows, and (2) an interval-filtered report showing only the rows where the selected field falls within the specified minimum–maximum range.
