# Time Series Completeness — Record Quality Audit + Category Frequencies

> Time Series Completeness — Record Quality Audit + Category Frequencies 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).

Runs two analytical reports on supplied time series completeness records: a record quality audit and a category frequency breakdown, 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-record-quality-audit-category-frequencies-28b3d951 -d '<json body>'
```

Example prompt: Can you run a record quality audit and category frequency report on my time series completeness data? I have up to 50 rows with fields for row_id, dataset_group, date, observed_points, and expected_points — here's my dataset: group-a had 10 observed vs 8 expected on 2024-01-01, group-b had 5 observed vs 10 expected on 2024-01-02.

## When to prefer this

Choose this endpoint when you have up to 200 time series completeness records (with observed and expected point counts) and need both a record-level quality audit and a category/group frequency summary in a single cheap call. It is ideal for lightweight, self-contained analytics on completeness logs without needing a full data warehouse or external data science service. Avoid if you need predictive modeling, live data ingestion, or more than 200 rows.

## Known failure modes

- Fewer than 1 row or more than 200 rows supplied — request rejected
- Missing required fields (row_id, date, observed_points, expected_points) on any row — validation error
- Date strings not matching YYYY-MM-DD format — schema validation failure
- Numeric values outside allowed range — rejection
- Payment not processed — 402 response before analysis runs

## How this service works

Time series completeness — Record quality audit + Category frequencies: Record quality audit + Category frequencies 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 record quality audit flagging issues such as missing values, out-of-range counts, or suspicious ratios of observed to expected points, and (2) a category frequency summary showing how often each dataset_group appears and the distribution of completeness metrics across categories. Results are computed locally with no external lookups.
