Connects to the LION x402 service for keyless token risk analysis on Base. Exposes holder concentration metrics like HHI and Gini coefficients, plus blockchain RPC calls and transaction decoding. The API includes compliance tools (sanctions screening, VAT validation), enrichment bundles for web and transaction data, and business intelligence endpoints (SEC financials, domain intel, social signals). Reach for this when you need to evaluate token holder distribution without managing API keys, or when building agents that assess DeFi risk before executing trades. The keyless design means you can query concentration metrics and on-chain data through a single authenticated MCP connection.
