# Observed Unit Sales Velocity – Rolling Mean Report

> Observed Unit Sales Velocity – Rolling Mean Report 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 rolling mean of observed retail unit sales velocity (units sold per day) across up to 200 supplied data rows using 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 observed-unit-sales-velocity-rolling-mean-report-2e4bf49d -d '<json body>'
```

Example prompt: Can you run a rolling mean report on my retail unit sales velocity data? I have 4 rows — {sold_units: 84, observed_days: 7}, {sold_units: 92.4, observed_days: 7.7}, {sold_units: 84, observed_days: 7}, {sold_units: 92.4, observed_days: 7.7} — and I want a window size of 2.

## When to prefer this

Choose this endpoint when you need a fast, bounded rolling mean computation over retail unit sales velocity data (sold units and observed days) and you already have the figures on hand. It is purpose-built for retail sales smoothing with a configurable window size up to 200 records, at a low fixed cost of $0.01 USDC per call. It does not provide live market rates, order execution, or platform data access — prefer it for offline or batch analytical smoothing of supplied retail figures.

## Known failure modes

- Fewer than 2 rows provided — minimum row count not met
- Window size larger than number of rows — rolling mean cannot be computed
- sold_units or observed_days values outside allowed bounds (negative or exceeding max)
- observed_days set to 0 — exclusiveMinimum violation
- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields sold_units or observed_days in one or more row objects
- Payment failure or insufficient USDC balance for the $0.01 per-call fee

## How this service works

Observed unit sales velocity - Rolling mean report: Rolling mean report for Observed unit sales velocity. Supplied retail figures only, up to 200 records. No platform access, live rates or order execution. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded rolling mean report report.

## Output

Returns a rolling mean report containing smoothed unit sales velocity values computed across the supplied rows of sold_units and observed_days using the specified window size. Output is bounded to the supplied retail figures only with up to 200 input records supported.
