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
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.
Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
token_check_safety | GET | /api/check | $0.008 | Check 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
| Name | Type | Required | Description |
|---|---|---|---|
address | string | yes | Token contract address (e.g. 0x...) |
chain | string | no | Chain to check on: 'ethereum' or 'base' (default: ethereum) |
Returns
isHoneypot-- whether the token traps buyers (cannot sell)ownershipRenounced-- whether the contract owner has renounced controlisProxy-- whether the contract is upgradeable (proxy risk)buyTax-- percentage tax on buy transactionssellTax-- percentage tax on sell transactionsmaxTxPercent-- maximum transaction size as percent of supplyliquidityLocked-- whether liquidity is lockedhasBlacklist-- whether contract has a blacklist functionholderCount-- total number of token holdersriskScore-- 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: 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
- "Check if a token is safe before buying or interacting with it"
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)
