Historical token price, Arc

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.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://apexfaucet.xyz/api/x402/arc-price-at", { method: "GET" });
console.log(await res.json());
