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 token-holder-growth-iqr-outlier-flags-85c82b66 -d '<json body>'
```

Example prompt: Check these token holder snapshots for IQR outliers — I have pairs of current and previous holder counts: (1100, 1000), (1210, 1100), (5000000, 1100), and (1210, 1100). Flag which observations are statistical outliers based on growth.

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01 USDC), deterministic IQR-based outlier check specifically on token holder growth data (pairs of current and previous holder counts). It is ideal for pre-publication data quality checks, anomaly triage, or batch validation of up to 200 observations without needing a full statistical library. Prefer alternatives if you need live blockchain scanning, real-time holder monitoring, or outlier detection on non-holder-count metrics.

## Known failure modes

- Fewer than 2 rows submitted — minimum batch size is 2 observations
- Missing required fields current_holders or previous_holders in any row
- Values of 0 or negative numbers rejected — both fields require exclusiveMinimum 0
- More than 200 rows submitted — exceeds maxItems limit
- Non-numeric values in holder count fields
- Payment failure or insufficient USDC balance (0.01 USDC required per call)

## How this service works

Reported token holder growth — IQR outlier flags: IQR outlier flags for Reported token holder growth. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded iqr outlier flags report.

## Output

A report indicating which of the submitted token holder growth observations are flagged as IQR outliers. Each row receives a deterministic verdict based on the interquartile range of computed growth values across the submitted batch. No live market data or safety guarantees are included — this is a pure statistical calculation on the caller-supplied observations.
