Red Dnsbl

by IP blocklist check in Developer tools

x402 APIPassing, checked 3 h ago

Checks one IPv4 address against nine public DNS blocklists at once — SpamCop, UCEPROTECT, PSBL, Barracuda, DroneBL and four more — and returns each list's raw return code plus the reason text the list itself publishes, not a score. Every list is re-checked on each call with its RFC 5782 test entry, so a dead list or one that refuses queries comes back as unavailable instead of reading as clean. Includes the delisting URL for each hit.

# See the payment challenge (nothing is charged)
curl -i -X GET "https://flat-rate-llm.kikoribera03.workers.dev/v1/red/dnsbl?ip=127.0.0.2"
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client().register(
  "eip155:8453",
  new ExactEvmScheme(privateKeyToAccount(process.env.AGENT_KEY)),
);
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? Preflight it first for $0.005:

const res = await pay("https://flat-rate-llm.kikoribera03.workers.dev/v1/red/dnsbl?ip=127.0.0.2");
