Top DEX pools by TVL

$0.001 per call · USDC via x402 · POST /api/dex-top-pools

Top DEX pools (Uniswap, Sushi, Curve, Aerodrome, etc.) ranked by current TVL - filterable by chain and project. Sourced from DeFiLlama's public Yields API (keyless). Each row carries chain, project slug, symbol pair, TVL in USD, current APY, and pool ID for follow-up queries.

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/dex-top-pools", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "chain": "Base",
    "project": "uniswap-v3",
    "limit": 5
  }),
});
