## 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 first-attempt-delivery-share-rolling-mean-report-0cdf3b6d -d '<json body>'
```

Example prompt: Can you calculate the rolling mean of my first-attempt delivery share using a window of 3? Here are my rows: 100 attempted with 87 delivered, 110 attempted with 96 delivered, 105 attempted with 91 delivered, 120 attempted with 104 delivered.

## When to prefer this

Use this endpoint when you need a simple, cost-effective rolling mean calculation on first-attempt delivery share data in the retail logistics domain, specifically when you have raw row-level shipment attempt counts and want a smoothed time-series output. Prefer this over general-purpose analytics platforms when working within the x402 micropayment ecosystem and need a bounded, lightweight computation on up to 200 records without requiring platform access or live data feeds.

## Known failure modes

- Fewer than 2 rows provided — minimum row count not met
- Window size larger than number of rows — insufficient data for any complete window
- Non-positive attempted_shipments value — exclusiveMinimum of 0 enforced
- Row count exceeds 200 — maxItems limit exceeded
- Window value outside 2–200 range — integer bounds violation
- Malformed row objects missing required fields attempted_shipments or first_attempt_deliveries

## How this service works

First-attempt delivery share - Rolling mean report: Rolling mean report for First-attempt delivery share. 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.
