Token Safety & Contract Risk API

Token contract safety scanner -- honeypot, tax, proxy, blacklist, ownership. Rug-pull protection for agents. 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-safety": {
      "url": "https://token-safety.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://token-safety.api.klymax402.com/api/check?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.
