Overview

Price impact for an Arc token: what buying and selling $10, $100 and $1,000 would really get, each quoted by the Uniswap v4 Quoter on the token's deepest USDC pool (simulated, nothing spent). Pass ?token=0x.... Returns the mid price, the pool and its fee, and for each size the tokens or USDC out, the effective price and the cost or loss against the mid price (fee and impact included). A pool whose hook refuses quotes, no USDC pool or a failed read is refused before payment. Custom sizes: add &sizes=25,250 (up to 5 dollar amounts, 1 to 1,000,000).
