About-hourly open-interest history for one Hyperliquid main-dex perp (BTC, ETH, SOL, ... any listed coin): open interest in coins and USD, mark price and hourly funding per snapshot, plus change over the window. Hyperliquid has no public OI history, so these are cryptofeed402's own snapshots (8-day retention). hours=1-192, default 24. Bad params 400, unknown symbol 404, no history 503, no charge.

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://cryptofeed402.site/oi/history/:symbol", { method: "GET" });
console.log(await res.json());
