# Shipment Costs Trailing Mean Series

> Shipment Costs 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 2026-10-15).

Computes a trailing (rolling) mean series over shipment cost or weight records grouped by carrier, returning smoothed time-series values for up to 200 rows.

## 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 shipment-costs-trailing-mean-series-cc91122c -d '<json body>'
```

Example prompt: Calculate a trailing mean series for my shipment cost data — I have 4 rows with carriers group-a and group-b dated 2026-10-01 through 2026-10-04 with shipping costs 1 through 4, and I want a rolling window of 3 on the shipping_cost field.

## When to prefer this

Choose this endpoint when you need a fast, local rolling/trailing mean computation on structured shipment records (up to 200 rows) without requiring external data enrichment or forecasting. Ideal for smoothing noisy cost or weight time-series data in logistics workflows where you control the input data and need a bounded, deterministic statistical series returned quickly at low cost ($0.01 USDC).

## Known failure modes

- Fewer than 1 row supplied — minimum item constraint violated
- Window size larger than number of rows — insufficient data for any mean calculation
- Invalid date format not matching YYYY-MM-DD pattern — schema validation error
- Numeric field values outside allowed range (±1 trillion) — rejected by schema
- More than 200 rows supplied — maxItems constraint exceeded
- Missing required fields (row_id, carrier, date, weight_kg, shipping_cost) — request rejected
- Payment not provided or insufficient — x402 payment required error

## How this service works

Shipment costs - Trailing mean series: Trailing mean series for Shipment costs. 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 bounded trailing mean series derived from the supplied shipment records, showing smoothed numeric values for the selected field (weight_kg or shipping_cost) computed over the specified rolling window, with one output value per record after the initial window is filled.
