# Product Feature Telemetry – Trailing Mean Series

> Product Feature Telemetry – 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 2026-10-17).

Computes a trailing (rolling) mean series over time-series product feature telemetry records, returning a smoothed time-series for events or unique users per feature group.

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 product-feature-telemetry-trailing-mean-series-7fb934f3 -d '<json body>'
```

Example prompt: Take these 50 daily telemetry rows for our 'dark-mode' and 'search-v2' features and compute a trailing mean series over a 7-day window for the events field — I want to see the rolling average to smooth out the noise.

## When to prefer this

Choose this endpoint when you need a fast, bounded rolling-mean smoothing computation over product feature telemetry (events or unique users) without requiring external enrichment, forecasting, or ML models. It is ideal for pre-processing noisy time-series data before visualization or reporting, especially when working with up to 200 records across multiple feature groups at low cost ($0.01 per call).

## Known failure modes

- Fewer than 1 row supplied — minimum item count validation failure
- Window size larger than the number of rows in a feature group — insufficient data for rolling calculation
- Invalid date format not matching YYYY-MM-DD pattern — schema validation error
- More than 200 rows supplied — exceeds maxItems limit
- Numeric values out of allowed range (±1 trillion) — schema rejection
- Missing required fields (row_id, feature, date, events, unique_users) — validation failure
- Payment not processed — x402 payment required error

## How this service works

Product feature telemetry - Trailing mean series: Trailing mean series for Product feature telemetry. 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

A trailing mean series report containing smoothed metric values (events or unique_users) per feature over time, calculated using the specified rolling window. The report covers up to 200 input records and provides local descriptive analytics with no forecasting or external enrichment.
