# Time Series Completeness: Numeric Distribution + Two-Measure Correlation

> Time Series Completeness: Numeric Distribution + Two-Measure Correlation 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).

Computes numeric distribution statistics and two-measure correlation for time series completeness records (observed_points vs expected_points) across up to 200 rows, returning two 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 time-series-completeness-numeric-distribution-two-measure-correlation-10555b6c -d '<json body>'
```

Example prompt: Can you analyze the distribution and correlation between observed_points and expected_points for my time series completeness data? I have records for group-a and group-b across October 2026 — row-1 through row-4 — and want both a numeric distribution report and a two-measure correlation report.

## When to prefer this

Choose this endpoint when you have pre-collected time series completeness records (observed vs expected data points) and need two types of quick statistical insight — numeric distribution and correlation — without requiring external lookups, predictions, or professional assessment. It is well-suited for data quality audits, pipeline monitoring, and batch completeness checks on up to 200 rows at very low cost ($0.01 USDC for both reports).

## Known failure modes

- Missing required fields (row_id, date, observed_points, expected_points) returns a validation error
- More than 200 rows submitted exceeds the maxItems limit and will be rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- All null values for the selected field may produce degenerate or empty distribution output
- Payment of 0.01 USDC not provided or rejected causes HTTP 402 error

## How this service works

Time series completeness — Numeric distribution + Two-measure correlation: Numeric distribution + Two-measure correlation for supplied time series completeness records (observed_points, expected_points). 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

Two independent analytical reports: (1) a numeric distribution summary (e.g. min, max, mean, percentiles, histogram bins) for the selected field across the submitted rows, and (2) a two-measure correlation analysis between observed_points and expected_points across the dataset. Results are computed locally from the supplied data with no external lookups.
