It is one of 26 DeFi-focused security and data endpoints hosted at defi.hugen.tokyo, all gated by the x402 payment protocol at $0.01 USDC per call on Base. The endpoint accepts a single required query parameter (`url`) and returns a phishing assessment.\n\nThe broader API suite covers token security audits (EVM and Solana), address and NFT security checks, rug-pull detection, dApp audits, approval security, malicious-address lookups, EVM transaction simulation, cross-chain bridge quoting/routing/status, gas prices, protocol analytics (TVL, fees, info), token prices, stablecoin data, and DEX volume. No API keys or rate limits are required — payment is handled per-call via x402. Alternative access methods include a broker API (with a free $0.05 credit key), an MCP server at mcp.hugen.tokyo with 58 tools, and a Python SDK (`x402-pay`).\n\nThe endpoint returned a valid 402 challenge when probed, confirming it is live. The OpenAPI 3.1 spec is published at `/openapi.json` and interactive docs are available at `/docs`. Response schemas for individual endpoints are not detailed in the spec (empty schema objects), so the exact shape of the phishing-check response is not documented.","tags":[],"capabilities":["phishing-detection","url-security-check","x402-micropayment","defi-security","no-api-key-required"],"categories":["security","defi","web3"],"synonyms":["phishing check","URL safety check","scam site detection","phishing URL scanner","DeFi phishing detector","web3 phishing API","crypto phishing lookup"],"warnings":["Response schema for /defi/phishing is not defined in the OpenAPI spec (empty schema object) — actual response shape is unknown.","No example responses or detailed field documentation available for this endpoint.","Root URL returns 404; documentation is only at /docs."],"endpointUrl":"https://defi.hugen.tokyo/defi/phishing","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":"0.550","qualityRationale":"The endpoint is live (402 challenge confirmed) and has a published OpenAPI 3.1 spec with clear parameter definitions.
