L2 TVL ranking

Top L2s by Total Value Locked (TVL) via DeFiLlama. Returns each L2 with TVL in USD, native token symbol, and CoinGecko/CMC ids. Classification combines DeFiLlama's parent-chain hint with a curated list of well-known L2s (Arbitrum, Optimism, Base, zkSync Era, Linea, Scroll, Mantle, Polygon zkEVM, Starknet, Blast, Mode, Manta, Metis, Polygon, Taiko, Immutable zkEVM, World Chain).

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 { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/l2-tvl", {

  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "limit": 10
