DeFi protocols ranked by TVL

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. Send POST /api/defi-protocols with no required fields (6 optional) and pay $0.002 per call over x402 or MPP (there is no free tier). It returns a JSON object with source, fetchedAt, cached, filters, totalTvlUsd and 3 more.

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.

Parameters

Example request

curl -i -X POST https://agent402.tools/api/defi-protocols \
  -H "Content-Type: application/json" \
  -d '{"category":"Lending","limit":5}'

Without payment this returns HTTP 402 Payment Required with the exact price for defi-protocols; any x402 v2 or MPP client pays it and retries.

The hosted connector at https://agent402.tools/mcp needs a payment for defi-protocols; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/defi-protocols returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

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();
client.setSpendControls?.(false); // keep your own spending ceiling in code
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",
    "limit": 5
  }),
});
