# Time Series Completeness — Duplicate Key Report + Equal-Width Histogram

> Time Series Completeness — Duplicate Key Report + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Analyzes time series completeness records (observed_points, expected_points) to produce a duplicate key report and an equal-width histogram for up to 200 rows.

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-duplicate-key-report-equal-width-histogram-11c05a6b -d '<json body>'
```

Example prompt: Run a duplicate key report and a 10-bin equal-width histogram on these time series completeness records I have for dataset groups 'sensor-a' and 'sensor-b' — use the observed_points field for the histogram.

## When to prefer this

Choose this endpoint when you need to simultaneously check for duplicate keys and understand the statistical distribution of completeness metrics across a time series dataset — ideal for data quality audits on completeness tracking records with up to 200 rows. Prefer this over single-report alternatives when both duplicate detection and histogram analysis are needed in one call at low cost.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Invalid date format (not YYYY-MM-DD) causes rejection
- bins value outside 1–30 range returns a validation error
- Empty rows array is not accepted (minItems: 1)
- Missing required fields (row_id, dataset_group, date, observed_points, expected_points) per row causes schema validation failure
- Non-numeric or out-of-range values for observed_points or expected_points may be rejected

## How this service works

Time series completeness — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 analytical reports: (1) a duplicate key report identifying rows with repeated row_id or date/dataset_group combinations, and (2) an equal-width histogram showing the frequency distribution of the selected field (observed_points or expected_points) across the specified number of bins. Both reports are computed locally from the supplied data with no external lookups.
