# Time Series Completeness — Base-100 Series + Keyed Dataset Comparison

> Time Series Completeness — Base-100 Series + 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 2026-10-19).

Analyzes time series completeness records by generating a Base-100 indexed series and a keyed dataset comparison report for up to 200 rows across two independent analyses.

## 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-base-100-series-keyed-dataset-comparison-8ff28eeb -d '<json body>'
```

Example prompt: Can you run a time series completeness analysis on my data — I have two datasets of up to 50 rows each with dates, dataset_group labels, observed_points, and expected_points — and give me both a Base-100 indexed series and a keyed comparison between the two datasets using the observed_points field?

## When to prefer this

Choose this endpoint when you need to analyze time series completeness data (observed vs expected points) and want two simultaneous analytical outputs — a Base-100 normalized series for trend benchmarking plus a keyed group comparison — without needing live data lookup, forecasting, or external enrichment. It is ideal for data quality auditing, pipeline monitoring, and completeness gap detection workflows where you supply your own data rows (up to 200) and need fast, local computation at low cost ($0.01 USDC for both reports).

## Known failure modes

- Input rows array is empty or exceeds 200 items — rejected with validation error
- Missing required fields (row_id, dataset_group, date, observed_points, expected_points) on any row
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Numeric values for observed_points or expected_points outside allowed range
- Payment not completed via x402 protocol — request rejected
- Null values in numeric fields may affect computation results

## How this service works

Time series completeness — Base-100 series + Keyed dataset comparison: Base-100 series + 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 Base-100 indexed time series showing completeness relative to a base value across dates, and (2) a keyed dataset comparison contrasting the two supplied datasets of completeness records — covering observed vs expected data points per row and group, all computed locally without external lookups.
