# Time Series Completeness — Equal-Width Histogram & Keyed Dataset Comparison

> Time Series Completeness — Equal-Width Histogram & 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 (observed vs expected data points) by generating an equal-width histogram and comparing two keyed datasets, producing two independent analytical reports for up to 200 rows.

## 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-equal-width-histogram-keyed-dataset-comparison-b03ebdf6 -d '<json body>'
```

Example prompt: Can you run a completeness analysis on my time series data — I have observed_points and expected_points for each date across two dataset groups (group-a and group-b), and I want an equal-width histogram with 10 bins plus a comparison between my primary dataset and a second reference dataset, up to 200 rows?

## When to prefer this

Choose this endpoint when you need both a distributional view (histogram) and a record-by-record comparison (keyed diff) of time series completeness data in a single paid call. Ideal for data quality audits where you have paired observed/expected counts per date and want to understand distribution shape and cross-dataset discrepancies simultaneously without external data lookups or predictions.

## Known failure modes

- More than 200 rows submitted — request rejected with max items error
- Missing required fields (row_id, dataset_group, date, observed_points, expected_points) in any row — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Bins parameter out of range (must be 1–30) — rejected
- Numeric values outside allowed range (±1,000,000,000,000) — validation failure
- Payment not included or insufficient — x402 payment required error

## How this service works

Time series completeness — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + 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

Two independent analytical reports: (1) an equal-width histogram dividing the selected field (observed_points or expected_points) into the specified number of bins with frequency counts per bin, and (2) a keyed dataset comparison that matches rows by key between the primary and secondary datasets to surface differences in time series completeness metrics.
