L2 TVL ranking

Top L2s by 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).

Input

Field	Type	Description
limit	number	Number of L2s to return (1-50, default 15).

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

Wallet-only. This tool reaches the network/browser/storage, so it is paid in USDC via x402 (no proof-of-work tier).
