With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability x402-trading-hub-holder-concentration-analysis-cd284112 -d '' ``` Example prompt: Can you check the holder concentration for the token at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want to know what percentage of supply the top wallets control and whether ownership is dangerously concentrated. ## When to prefer this Use this endpoint when you need quantitative on-chain holder concentration data for a specific token — particularly useful for due diligence before investment, assessing manipulation risk, or evaluating governance decentralization. Prefer this over general market data APIs when you specifically need wallet distribution and whale dominance metrics rather than price or volume data. ## Known failure modes - Invalid or unrecognized token contract address returns an error - Unsupported blockchain network not covered by the service - Token has insufficient on-chain data or is too new for meaningful analysis - Payment not received or x402 payment header missing results in 402 response - Rate limiting or timeout if on-chain data indexing is slow ## How this service works 67 paid endpoints for on-chain, forex, stocks & market intelligence ## Output Returns holder concentration metrics for the specified on-chain token, including percentage of supply held by the top N wallets, a concentration or Gini score indicating how evenly distributed ownership is, and potentially a breakdown of whale vs. retail holder segments. ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/x402-trading-hub-holder-concentration-analysis-cd284112/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from trading-hub-v4-omega.vercel.app](https://www.zero.xyz/host/trading-hub-v4-omega.vercel.app/llms.txt)
