Token Holders API

MCP Server x402 License: MIT

Token holder analysis — top holders, concentration metrics, whale detection. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "token-holders": {
      "url": "https://token-holders.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://token-holders.api.klymax402.com/api/holders?address=0x0000000000000000000000000000000000dEaD"
# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Use this when you need to analyze token holder distribution.

Do NOT use for token price data — use token_get_ohlcv. Do NOT use for token safety — use token_check_safety. Do NOT use for liquidity depth — use dex_analyze_orderbook_depth.
