# Null Coverage Analytics — Numeric Distribution & Daily Sum Series

> Null Coverage Analytics — Numeric Distribution & Daily Sum Series 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).

Generates two local analytical reports (numeric distribution and daily sum time series) for null coverage data (missing_values, total_values) across 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 null-coverage-analytics-numeric-distribution-daily-sum-series-8e43b7c7 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and daily sum series analysis on my null coverage data? I have 150 rows with row IDs, dataset groups, dates, missing_values, and total_values — analyze the missing_values field.

## When to prefer this

Choose this endpoint when you have raw null coverage records (missing_values and total_values per row with dates and group labels) and need two ready-made statistical reports — a numeric distribution and a daily sum time series — computed locally without any external data lookups, predictions, or professional assessments. It is ideal for data quality audits, completeness monitoring, and batch summaries of up to 200 records at a low flat cost of $0.01 USDC for both reports.

## Known failure modes

- Input array is empty (minItems:1 violated) — request rejected
- More than 200 rows supplied (maxItems:200 violated) — request rejected
- Date field does not match YYYY-MM-DD pattern — validation error
- missing_values or total_values outside allowed range (±1,000,000,000,000) — validation error
- Invalid field enum value (must be 'missing_values' or 'total_values') — rejected
- row_id missing or empty string — schema validation failure

## How this service works

Null coverage — Numeric distribution + Daily sum series: Numeric distribution + Daily sum series 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 two analytical reports computed locally from the supplied rows: (1) a numeric distribution of the selected field (missing_values or total_values) showing frequency/spread, and (2) a daily sum time series aggregating the field by date — covering up to 200 input rows with no external lookups or live data.
