# Product Feature Telemetry - Secondary-Measure Weighted Mean

> Product Feature Telemetry - Secondary-Measure Weighted Mean 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).

Computes a secondary-measure weighted mean (e.g. events weighted by unique_users) across product feature telemetry records, returning a local descriptive analytics report.

## 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-secondary-measure-weighted-mean-a8778813 -d '<json body>'
```

Example prompt: Can you compute the secondary-measure weighted mean for my product feature telemetry — I have 4 rows of daily data: feature 'group-a' on 2026-10-01 with 10 events and 1 unique user, 'group-b' on 2026-10-02 with 20 events and 2 unique users, 'group-a' on 2026-10-03 with 15 events and 3 unique users, and 'group-b' on 2026-10-04 with 30 events and 4 unique users — weight the 'events' field by unique_users?

## When to prefer this

Choose this endpoint when you have up to 200 product feature telemetry records and need a secondary-measure weighted mean as a local, self-contained descriptive statistic — no ML, forecasting, or external data enrichment required. Prefer this over general-purpose analytics tools when you want a cost-effective ($0.01 USDC), bounded computation on structured daily feature usage data.

## Known failure modes

- Empty or missing rows array returns validation error
- More than 200 rows supplied exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Null values in numeric fields may affect mean calculation
- Invalid field enum value (not 'events' or 'unique_users') causes rejection
- Payment of 0.01 USDC not fulfilled causes 402 error
