Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 at-least-one-solo-block-probability-iqr-outlier-flags-4a4d23fa -d '<json body>'
```

Example prompt: Flag IQR outliers in solo block probability for these mining scenarios: 100 days at 0.01 expected blocks per day, 110 days at 0.011 expected blocks per day, 50 days at 0.005 expected blocks per day, and 200 days at 0.02 expected blocks per day.

## When to prefer this

Choose this endpoint when you need statistical outlier detection (IQR method) specifically applied to at-least-one solo block probability in cryptocurrency mining scenarios. It is purpose-built for screening multiple mining parameter combinations (up to 200 rows) for anomalous probability values. Prefer it over generic statistics APIs when working within the mining block probability domain and needing a low-cost ($0.01 USDC), bounded, formula-disclosed report.

## Known failure modes

- Fewer than 2 rows supplied — minItems constraint violated
- Row missing required fields expected_blocks_per_day or days
- Non-positive values for days or expected_blocks_per_day — exclusiveMinimum violated
- More than 200 rows submitted — maxItems exceeded
- Extremely large values approaching floating-point limits may produce unreliable probability estimates
- Payment of 0.01 USDC not provided or rejected — endpoint returns 402

## How this service works

At-least-one solo block probability — IQR outlier flags: IQR outlier flags for At-least-one solo block probability. Supplied mining assumptions only; formula and units disclosed. No live prices, mining or guaranteed return. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded iqr outlier flags report.

## Output

Returns a bounded IQR outlier flags report for each input row, indicating which mining scenarios (defined by expected_blocks_per_day and days) are statistical outliers in terms of at-least-one solo block probability, using interquartile range methodology. Formula and units are disclosed; no live prices or guaranteed returns are included.
