This bridge plugs Claude and other MCP clients into the LogicNodes x402 marketplace, giving your agent access to 619 pay-per-call microservices across finance, DeFi, crypto, healthcare, legal, and supply chain domains. No API key or signup required by default. Your agent's wallet pays micro-amounts in USDC per call using the x402 protocol. Services pull live data from CoinGecko, DefiLlama, DexScreener, Alchemy, and others, with support for Base, Solana, Arbitrum, Optimism, Polygon, Ethereum, Arc, and World Chain. Pricing ranges from $0.001 to $0.50 per call depending on the service tier. Reach for this when you need deterministic external computation or live blockchain data without managing API keys or subscriptions.
Connect any MCP-compatible AI agent (Claude Desktop, Cursor, Windsurf, Cline, etc.) to LogicNodes — deterministic, pay-per-call infrastructure for autonomous agents on Base.
