Agent Intel Typosquat Phishing Domain Radar

x402 APIFailing, checked 7 h ago

For a brand domain (e.g. paypal.com), builds up to 15 look-alike variants (omitted, doubled and swapped letters, 0/1 homoglyphs, hyphen and login additions, other TLDs) and checks which are registered, using the public RDAP directory. Registered means taken, not malicious: each one needs a content check. Unicode homoglyphs (IDN) are not generated.

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://api.fadeandco.workers.dev/api/agent-intel/typosquat-phishing-domain-radar?brand=paypal.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://api.fadeandco.workers.dev/api/agent-intel/typosquat-phishing-domain-radar?brand=paypal.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";

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
