Perp dexs (HIP-3 builder-deployed)

Every builder-deployed perpetuals dex on Hyperliquid (HIP-3): dex name, full name, deployer, oracle updater and fee recipient, how many markets it lists (active vs delisted, so a wound-down dex reads as one), how many assets carry a streaming open-interest cap and the cap total, plus the current perp-deploy auction (start, end, start/current/end gas). The native dex is not a row; use perp-markets for it. Keyless public data.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";

import { registerExactEvmScheme } from "@x402/evm/exact/client";

import { metaTitle, metaDescription } from "./seo-meta.js";

const client = new x402Client();
client.setSpendControls?.(false); // @x402/core 2.23+ refuses anything over $1 or off the pegged-asset list by default; keep your own ceiling in code instead
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);
