## 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 return-on-average-assets-iqr-outlier-flags-82987f6c -d '<json body>'
```

Example prompt: Can you check my return on average assets data for statistical outliers using IQR? Here are four observations: net income of 3000 and average assets of 40000, net income of 3300 and average assets of 44000, net income of 500 and average assets of 42000, and net income of 3000 and average assets of 40000.

## When to prefer this

Use this endpoint when you need a bounded, reproducible IQR-based statistical outlier flag on a batch of return-on-average-assets observations (up to 200 rows) and want a structured JSON result with the formula and caveats included. Prefer it over generic statistics libraries when you need a pay-per-call, auditable report with built-in financial metric context and no setup overhead. Not suitable for live data feeds, fraud detection conclusions, or financial advice.

## Known failure modes

- Fewer than 2 rows supplied — minItems validation failure
- average_assets value of zero or negative — exclusiveMinimum validation error
- net_income or average_assets exceeds ±1,000,000,000,000 — maximum/minimum boundary error
- More than 200 rows submitted — maxItems validation failure
- Non-numeric values in net_income or average_assets fields — type validation error
- Payment not included or insufficient — 402 payment required response

## How this service works

Return on average assets - IQR outlier flags: Flag observations beyond 1.5 times the interquartile range; statistical flags are not errors or fraud findings. Metric: Return on average assets. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded iqr outlier flags report.

## Output

A JSON object containing an outlier-flag report for each submitted observation, specifying which rows fall beyond 1.5× the interquartile range of the computed return-on-average-assets values, along with the formula used, units, and a limitations disclaimer. Flags are statistical only and do not imply errors or fraud.
