# Token Holder-Address Density IQR Outlier Flags

> Token Holder-Address Density IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes IQR-based outlier flags for token holder-address density (holders per million USD of market cap) across a batch of supplied token observations.

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-address-density-iqr-outlier-flags-57e4fa2c -d '<json body>'
```

Example prompt: Flag any outliers in holder-address density for these tokens: first token has 1000 holders and $2,000,000 market cap, second has 50,000 holders and $1,500,000 market cap, third has 800 holders and $3,000,000 market cap — use IQR outlier detection.

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC), deterministic IQR-based outlier detection on token holder-to-market-cap density from your own supplied data — not a live blockchain scan. Ideal for batch screening of 2–200 token observations where you already have holder count and market cap figures and want a statistical flag without a full distribution model or live data feed.

## Known failure modes

- Fewer than 2 rows submitted — minimum 2 observations required for IQR calculation
- More than 200 rows submitted — exceeds maxItems limit
- Zero or negative holder count or market cap — exclusiveMinimum constraint violated
- Missing required fields (holders or market_cap_usd) in any row — validation error
- Payment not completed — x402 payment required before response is returned

## How this service works

Token holder-address density — IQR outlier flags: IQR outlier flags for Token holder-address density. 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

Returns IQR-based outlier flags for each submitted token observation, indicating whether each token's holder-address density (holders per million USD of market cap) falls outside the interquartile range bounds. Results are deterministic verdicts based solely on the supplied data batch, not live blockchain scans or safety ratings.
