Live on-chain data for Base Mainnet — gas, DEX arbitrage, whale tracking, Aave flash loans & liquidation, token security, contract profiling. Pay per call in USDC via x402. No API key, no subscription. MCP server included.

Hey PH 👋 I built a pay-per-call API hub for Base Mainnet that works natively with AI agents (Claude, GPT, any MCP client) using the x402 protocol — payments in USDC, fractions of a cent per call. 17 live endpoints. Why it's different: • No API key, no account, no subscription. Call the endpoint; if you don't pay you get HTTP 402 with everything needed to pay and retry automatically. • Free trial on basic endpoints: 1 call per IP every 24h — agents discover and test with zero setup. • MCP server built in — drop the URL into Claude Desktop or any MCP client and it just works. • All 17 endpoints read real data on-chain (Alchemy, Aave v3, Uniswap v3, Aerodrome v2, GoPlus). No mocks. What you get: 🔍 Gas Optimizer · 💲 Token Prices · ▪ Contract Profile/Read · 👛 Wallet Portfolio · 🌱 Aave Yield · ▪ DEX Arbitrage · 🐋 Whale Tracker · ⚡ Flash Loans · 🛡️ Token Security · 📉 Liquidation Monitor · → Deploy Radar · 🎯 Slippage · 🗺️ Market Snapshot · 🔎 Due Diligence Prices: $0.002 – $0.01 per call.

MCP endpoint: https://auditor-x402.onrender.com/mcp/v1 — add it directly in Claude Desktop or any MCP client. Machine-readable catalog at /pricing, OpenAPI at /openapi.json. Free trial on basic endpoints: 1 call per IP every 24h, no setup.
