Token Safety & Contract Risk API

br0ski777/token-safety-x402
34 toolsSSEregistry active
Summary

This server wraps the GoPlus security API to help you screen cryptocurrency tokens before trading or recommending them. It checks for common contract risks like honeypot scams, excessive taxes, proxy patterns, blacklist functions, and generates an overall risk score. You'd reach for this when building crypto trading bots or AI agents that need to evaluate token safety on chains like Ethereum or BSC. The service runs on a paid API at x402 USDC and connects via server-sent events, so you can query token addresses and get back structured safety data without managing your own blockchain scanning infrastructure.

Token Safety & Contract Risk API

MCP Server x402 License: MIT

Token contract safety scanner — honeypot, tax, proxy risk, blacklist, ownership. GoPlus-powered. 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=0x...&chain=base"
# → 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. No manual key exchange.

Tools

ToolMethodPathPriceDescription
token_check_safetyGET/api/check$0.003Check token contract safety and risk score

token_check_safety

Use this when you need to check if a token is safe before buying or interacting with it. Returns a comprehensive safety report in JSON.

Parameters

NameTypeRequiredDescription
addressstringyesToken contract address (e.g. 0x...)
chainstringnoChain to check on: ethereum or base (default: ethereum)

Returns

  • isHoneypot — whether the token traps buyers (cannot sell)
  • ownershipRenounced — whether the contract owner has renounced control
  • isProxy — whether the contract is upgradeable (proxy risk)
  • buyTax / sellTax — percentage tax on buy/sell transactions
  • maxTxPercent — maximum transaction size as percent of supply
  • liquidityLocked — whether liquidity is locked
  • hasBlacklist — whether the contract has a blacklist function
  • holderCount — total number of token holders
  • riskScore — overall risk score (0 = safe, 100 = dangerous)

Example response:

{"isHoneypot":false,"ownershipRenounced":true,"isProxy":false,"buyTax":0,"sellTax":0,"maxTxPercent":100,"liquidityLocked":true,"hasBlacklist":false,"holderCount":15420,"riskScore":12}

When to use: before buying any new or unknown token — essential for rug-pull protection and due diligence.

Not for: token prices (use dex_get_swap_quote), wallet balance (use wallet_get_portfolio), holder distribution (use token_get_holder_analysis).

Example agent prompts

  • "Is this token safe to buy? 0x1234...5678 on Base"
  • "Check for honeypot risk before I swap into this contract"
  • "Run a rug-pull check on this new token launch before I ape in"

Payment

  • Protocol: x402 — HTTP-native pay-per-call, no signup, no API key
  • Network: Base L2 (eip155:8453)
  • Asset: USDC
  • Facilitator: Coinbase CDP (primary), PayAI (fallback)
  • Also reachable via ATXP (OAuth-wrapped x402, RFC 9728 protected-resource metadata)

Part of klymax402

100 x402 micropayment APIs for AI agents — one wallet, USDC on Base, zero signup.
