# Null Coverage Base-100 Series and Keyed Dataset Comparison

> Null Coverage Base-100 Series and 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 2026-10-14).

Computes base-100 indexed null coverage trends and compares two keyed datasets for missing/total value patterns across up to 200 rows using local analytical engines.

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-base-100-series-and-keyed-dataset-comparison-02097830 -d '<json body>'
```

Example prompt: Can you run a base-100 null coverage analysis and dataset comparison on these two sets of records — I have up to 50 rows in each group with date, row_id, dataset_group, missing_values, and total_values fields, and I want to compare null rates across the groups using the missing_values field?

## When to prefer this

Choose this endpoint when you need to analyze null coverage patterns across up to 200 rows of supplied data using both a base-100 indexed time series and a direct comparison between two keyed datasets. It is ideal for data quality audits, pipeline completeness monitoring, and vendor benchmarking where you already have the data locally and need structured analytical output without any external data lookup, prediction, or live enrichment. At $0.01 USDC for two reports, it is cost-effective for batch quality assessments on small-to-medium datasets.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, dataset_group, date, missing_values, total_values) — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — rejected
- Empty rows array (minItems: 1 not met) — error returned
- Payment not included or insufficient — x402 payment required response

## How this service works

Null coverage — Base-100 series + Keyed dataset comparison: Base-100 series + Keyed dataset comparison 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 independent analytical reports: (1) a base-100 indexed series showing null coverage trends over time for the supplied rows, and (2) a keyed dataset comparison report contrasting the primary and secondary datasets on missing or total value metrics. Both reports are computed locally with no external lookups. Up to 200 rows per dataset are supported.
