## 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-iqr-outlier-flags-96e90ab9 -d '<json body>'
```

Example prompt: Can you flag any IQR outliers in this retail sales velocity dataset? I have 6 records — 84 units over 7 days, 200 units over 7 days, 90 units over 8 days, 88 units over 7 days, 85 units over 7 days, and 300 units over 7 days.

## When to prefer this

Choose this endpoint when you need a quick, cost-effective statistical outlier check on retail unit sales velocity data using the IQR method, specifically for supplied retail figures (not live or platform data). Ideal for batch analysis of up to 200 records at $0.01 USDC per call when you want a bounded, reproducible outlier report without needing real-time rates or order execution.

## Known failure modes

- Fewer than 2 rows submitted — minimum 2 records required
- More than 200 rows submitted — exceeds maxItems limit
- observed_days set to 0 or negative — exclusiveMinimum constraint violation
- sold_units or observed_days outside allowed numeric range
- Malformed row objects with extra properties — additionalProperties is false
- Payment not provided or insufficient USDC — x402 payment required

## How this service works

Observed unit sales velocity - IQR outlier flags: IQR outlier flags 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 iqr outlier flags report.

## Output

A bounded IQR outlier flags report identifying which of the submitted retail records (up to 200) have sales velocity values that fall outside the interquartile range, flagging statistical anomalies in unit sales per observed day.
