# Web Traffic Trailing Mean Series

> Web Traffic 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 2026-10-18).

Computes a trailing (rolling) mean time series for web traffic sessions or conversions across up to 200 typed records, grouped by channel and date, with a configurable window size.

## 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-trailing-mean-series-81eb9ff9 -d '<json body>'
```

Example prompt: Calculate the trailing mean series for my web traffic sessions data — I have 4 rows across two channels (group-a and group-b) from 2026-10-01 to 2026-10-04, and I want a rolling window of 3.

## When to prefer this

Choose this endpoint when you need a local, privacy-safe, no-external-dependency computation of a rolling mean over web traffic time series data (sessions or conversions). It is ideal for smoothing noisy daily web analytics data across multiple channels without sending data to a third-party analytics platform. Prefer it over full analytics suites when you already have structured tabular traffic data and just need the trailing mean calculation applied at low cost ($0.01 USDC per call) for up to 200 records.

## Known failure modes

- Fewer than 1 row supplied returns a validation error
- Window size larger than number of rows produces partial/null results for early rows
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Sessions or conversions values outside ±1,000,000,000,000 rejected
- More than 200 rows supplied exceeds maxItems and is rejected
- Missing required fields (row_id, channel, date) cause validation failure
- Non-numeric sessions/conversions values (unless null) cause type errors

## How this service works

Web traffic - Trailing mean series: Trailing mean series 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 trailing mean series deliverable.

## Output

Returns a trailing (rolling) mean series: for each input row, the endpoint computes the average of the target field (sessions or conversions) over the preceding N rows (window), grouped appropriately by sequence. Output includes per-row smoothed values, preserving row_id and channel context, with data-quality indicators for rows where the window is not yet fully populated.
