Domain Age Check

by NetIntel in Developer tools

x402 APIPassing, checked 1 h ago

Determine a domain's age from registration data and archival history — tries RDAP, then port-43 WHOIS, then a Wayback-based estimate (age_source: rdap | whois | wayback_estimate | null), returning creation date, age in years, first Wayback capture, archived snapshot count, and a maturity signal so agents can assess trustworthiness and detect freshly registered domains used for fraud or phishing — including .io and TLDs without public RDAP.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.03.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://netintel.dev/domain-age/check?domain=example.com'

# 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://netintel.dev/domain-age/check?domain=example.com' \
  | 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 $0.03 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.03" });
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 $0.03 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fnetintel.dev%2Fdomain-age%2Fcheck
const res = await pay("https://netintel.dev/domain-age/check?domain=example.com");
console.log(res.status, await res.text());
Python: pay and call
# pip install "x402[requests,evm]"

with x402_requests(client) as session:
