# Data Validation Results – Trailing Mean Series

> Data Validation Results – Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Computes a rolling/trailing mean time series over data validation metrics (checked_records or failed_records) grouped by rule, for up to 200 supplied records.

## 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 data-validation-results-trailing-mean-series-e5884130 -d '<json body>'
```

Example prompt: Compute a trailing mean series for my data validation results — I have records with dates, rule names, checked_records, and failed_records for about 50 entries; use a window of 7 and calculate the rolling mean over failed_records.

## When to prefer this

Choose this endpoint when you need a quick, local rolling/trailing mean computation on your own data validation metrics (checked_records or failed_records) without sending data to a full analytics platform. It is ideal for smoothing noisy daily validation counts, spotting trends in rule-level failure rates, or generating a clean time series for reporting — all at very low cost ($0.01 per call) and with no external data enrichment or forecasting. Prefer alternatives if you need forecasting, anomaly detection, or enrichment beyond descriptive rolling statistics.

## Known failure modes

- Fewer than 1 row supplied returns a validation error
- More than 200 rows supplied exceeds the maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Window size larger than the number of records for a given rule yields sparse or missing mean values
- Non-numeric or null values in the selected field may produce null averages for affected windows
- Malformed row_id or rule strings exceeding maxLength are rejected

## How this service works

Data validation results - Trailing mean series: Trailing mean series for Data validation results. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded trailing mean series report.

## Output

Returns a trailing mean series report: for each record in the input, a smoothed rolling average value computed over the specified window for the selected field (checked_records or failed_records), grouped by rule, with one bounded trailing mean series report per call. No enrichment or forecasting is included — purely local descriptive analytics.
