Overview

Historical token price on Arc, batch: ?q=0xTOKEN@BLOCK,0xTOKEN@BLOCK (up to 50 pairs) returns each token's USD price AT each block, read from its deepest Uniswap v4 USDC pool with an eth_call at that block. For history values, P&L and tax exports. A pool that did not exist yet answers null with the reason. Malformed input, a future block, or not one pair priceable is refused before payment.
