## 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 web-traffic-secondary-measure-weighted-mean-9cc01178 -d '<json body>'
```

Example prompt: I have web traffic data for two channels over the past week — compute the secondary-measure weighted mean of sessions (weighted by conversions) across these rows: group-a on 2026-10-01 had 10 sessions and 1 conversion, group-b on 2026-10-02 had 20 sessions and 2 conversions, group-a on 2026-10-03 had 15 sessions and 3 conversions, and group-b on 2026-10-04 had 30 sessions and 4 conversions.

## When to prefer this

Choose this endpoint when you have structured web traffic records with both sessions and conversions and need a statistically sound weighted average that accounts for traffic volume differences across channels or dates. Prefer this over simple arithmetic means when you want higher-traffic periods or channels to contribute proportionally more to the result.

## Known failure modes

- Empty or missing rows array returns validation error
- Row count exceeding 200 items rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Null values in both sessions and conversions may produce undefined weighted mean
- Missing required fields (row_id, channel, date) cause request rejection

## How this service works

Web traffic - Secondary-measure weighted mean: Secondary-measure weighted mean for Web traffic. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded secondary-measure weighted mean deliverable.

## Output

Returns a single weighted mean value computed from the supplied web traffic records, where one numeric field (sessions or conversions) is weighted by the other secondary measure across all provided rows.
