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 einstein-ai-x402-api-token-holder-concentration-analysis-f6eaec1d -d '<json body>'
```

Example prompt: What does the holder concentration look like for token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — show me the top 20 holders and how concentrated the ownership is?

## When to prefer this

Use this endpoint when you need on-chain holder distribution and concentration data for a specific EVM token, especially when assessing decentralization, whale risk, or token health on Ethereum, Base, BSC, Arbitrum, or Polygon. Prefer over generic block explorers when you need structured, programmatic distribution metrics.

## Known failure modes

- Missing tokenAddress returns a 400 or error response
- Unsupported chain value returns an error
- Invalid token address format causes a query failure
- Token not found on specified chain returns empty or null results
- Payment not included or insufficient triggers 402 payment required

## How this service works

Calculate holder concentration metrics and distribution analysis for any token. Supported chains: ethereum, base, bsc, arbitrum, polygon. Default chain: base. Required params: tokenAddress.

## Output

Returns holder concentration metrics and distribution analysis for the specified token, including data on how ownership is spread across wallets, whale concentration, and holder counts on the requested chain.
