On-chain DEX pool data API: reads Uniswap v2/v3-compatible liquidity pools from Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, and Avalanche via JSON-RPC — no third-party data vendor. Auto-detects pool type; returns token addresses, symbols, decimals, spot price both directions, v3 fee tier, sqrtPriceX96 and in-range liquidity, or v2 decimal-adjusted reserves. For price discovery, liquidity checks, and trading agents needing trustless pair state. Cached up to 30 seconds.
