Token Safety X402
Token Safety & Contract Risk API
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.
