Price API
Live token price in USD by ticker symbol or contract address on OP Mainnet - any ERC-20, not a fixed list. Real-time spot price read from SushiSwap and Uniswap v3 fee tiers pools at call time. What is this token worth right now. Returns priceUsd, the pair used, the USD liquidity backing the quote and a confidence rating, so a thin-pool number is never passed off as a market price. Onchain market data for trading bots and price oracles on Optimism / OP L2.
