x402 APIPassing, checked 4 h ago

Resolve DNS records for a domain via Cloudflare DNS-over-HTTPS — A, AAAA, MX, TXT, NS, CNAME, SOA. Pass name= and type= (default A). Returns each record with its TTL, plus NXDOMAIN when the name does not exist. The DNS commodity agents call constantly for infra, email and domain checks, served at the sub-cent floor. Not financial advice.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/dns-lookup?name=coinbase.com&type=A'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://402.com.tr/api/x402/dns-lookup?name=coinbase.com&type=A' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

// Pays at most $0.002 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.002" });
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
// client: this one is capped at $0.002 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2F402.com.tr%2Fapi%2Fx402%2Fdns-lookup
const res = await pay("https://402.com.tr/api/x402/dns-lookup?name=coinbase.com&type=A");
console.log(res.status, await res.text());
Python: pay and call
# pip install "x402[requests,evm]"

client = x402ClientSync().set_spend_controls({"max_amount_per_payment": "$0.002"})
register_exact_evm_client(client, EthAccountSigner(Account.from_key(os.environ["EVM_PRIVATE_KEY"])))

with x402_requests(client) as session:
    res = session.get("https://402.com.tr/api/x402/dns-lookup?name=coinbase.com&type=A")
    print(res.status_code, res.text)
