# Time Series Completeness — Secondary-Measure Weighted Mean & Keyed Dataset Comparison

> Time Series Completeness — Secondary-Measure Weighted Mean & 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 2026-10-24).

Computes secondary-measure weighted mean and performs keyed dataset comparison on up to 200 rows of time series completeness records (observed_points vs expected_points), returning two independent analytical reports.

## 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-secondary-measure-weighted-mean-keyed-626db122 -d '<json body>'
```

Example prompt: I have two datasets of daily completeness records for groups A and B from October 2026 — each row has a row_id, dataset_group, date, observed_points, and expected_points. Can you run a secondary-measure weighted mean on observed_points and compare the two datasets key-by-key to spot differences?

## When to prefer this

Choose this endpoint when you need two complementary analytical reports on time series completeness data in a single low-cost call ($0.01 USDC): a weighted mean that uses one completeness measure to weight the other, and a side-by-side keyed comparison between two dataset versions. It is ideal for data quality auditing, pipeline health checks, or before/after completeness comparisons across named groups, with up to 200 rows per call. It does not perform predictions, live lookups, or external actions.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, dataset_group, date, observed_points, expected_points) — validation error
- Date strings not matching YYYY-MM-DD pattern — schema rejection
- Null values in numeric fields may affect weighted mean calculation
- 'other' dataset missing or malformed — comparison report may be incomplete or error
- Payment not completed via x402 protocol — request not processed

## How this service works

Time series completeness — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison 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

Returns two independent analytical reports: (1) a secondary-measure weighted mean computed over the primary rows using the selected field (observed_points or expected_points) weighted by the secondary measure, and (2) a keyed dataset comparison between the primary rows and the 'other' dataset, identifying matching, differing, and missing row keys — all computed locally with no external lookups.
