DeFi protocols ranked by TVL

$0.003 per call · USDC via x402 · POST /api/defi-protocols

DeFi protocols ranked by current TVL from DefiLlama's free protocol list: filter by category (Lending, Dexs, Liquid Staking, CDP, Yield...), chain (ranks by that chain's TVL), or a name search; limit up to 100. Rows carry global rank, name, slug, category, chains, TVL, 1h/1d/7d TVL change, market cap and mcap/TVL. CEX rows are excluded unless category is CEX or includeCex is true. The ~8.6MB upstream document is cached 5 minutes in-process. 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 { 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/defi-protocols", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "category": "Lending",
