It returns a verdict including whether the address is malicious, the types of malicious behavior detected (if any), and a safety tag. The endpoint is part of a broader suite of 26 DeFi security and data endpoints covering token audits, rugpull detection, phishing checks, bridge routing, protocol analytics, and more.\n\nThis specific endpoint accepts a single required query parameter `address` (the wallet or contract address to check) and returns JSON with fields such as `is_malicious_address`, `malicious_behavior`, and `tag`. Payment is handled via the x402 protocol at $0.01 USDC per call on Base. No API key or account setup is required — callers pay per request using x402-compatible wallets or the provider's broker/SDK alternatives. The API also offers an MCP transport at mcp.hugen.tokyo and a Python SDK (`x402-pay`) for simplified integration.\n\nThe endpoint is live and returned a 402 challenge with a sample response during probing. The OpenAPI spec (v3.1) is published at `/openapi.json` and interactive docs are available at `/docs`. Response schemas for this endpoint are not fully specified in the OpenAPI document (the 200 response schema is empty), so the exact response shape is inferred from the sample embedded in the 402 challenge.","tags":[],"capabilities":["malicious-address-detection","defi-security","address-screening","x402-micropayment","per-call-payment","no-api-key-required","multi-chain-support"],"categories":["security","defi","blockchain"],"synonyms":["malicious address check","address risk screening","wallet blacklist check","address security audit","blockchain address reputation","DeFi address safety","scam address detection"],"warnings":["Response schema for 200 is not defined in the OpenAPI spec; response structure inferred from 402 challenge sample only","No detailed documentation on which chains or data sources back the malicious check","Root URL returns 404; no landing page or standalone docs site"],"endpointUrl":"https://defi.hugen.tokyo/defi/malicious","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"D6ZhtNQ5nT9ZnTHUbqXZsTx5MH2rPFiBBggX4hY1WePM"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"5000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.650","qualityRationale":"The endpoint is live (402 challenge captured with sample response), has a published OpenAPI 3.1 spec, and interactive docs.
