Overview

AI-generated overview

A remote MCP server that gives an assistant paid DNS, WHOIS/RDAP, IP and domain-report lookups, billed per call in USDC or prepaid credits.

What it does
Exposes four lookup tools: lookup_dns for record types such as A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, PTR and SRV; lookup_whois for registrar, creation, expiry, status and nameserver data via RDAP; lookup_ip for network owner, range, country and reverse DNS; and lookup_domain_report, which combines registration, DNS, email provider, SPF/DMARC and hosting in one call. Listing tools is free; each tool call is paid. Data comes from DNS over HTTPS and authoritative registry RDAP servers.
When to use it
Useful when an assistant needs domain or network intelligence during a task, such as checking who owns a domain, verifying DNS or mail authentication records, or profiling a host's network and hosting before further work. It suits occasional lookups where paying per call is simpler than signing up for a service.
Requirements
A remote Streamable HTTP endpoint; no local runtime or package is needed. Either an Authorization header with a Bearer credits API key obtained from the credits purchase endpoint, or an x402-capable client that pays per call in USDC on Base or Algorand. Network access to the endpoint is required.
Before you install
Tool calls cost money: prices range from $0.005 to $0.02 USDC per call, and prepaid credits are bought in amounts from $1 to $500. Paying per call with x402 requires a client that signs USDC payments, which means handling a wallet private key or equivalent signing credential. The Authorization header carries a credits API key that should be kept secret. Lookup queries are sent to the provider's endpoint.

Endpoints and pricing

Same price on Base and Algorand. Invalid input is rejected before payment, and x402 payments are only settled if the call succeeds — failed calls cost nothing.

Paying

x402 (no account)

Call any endpoint. You get 402 Payment Required with a base64 PAYMENT-REQUIRED header (x402 v2) offering:

  • Base — eip155:8453, USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, exact scheme (EIP-3009)
  • Algorand — algorand:wGHE2Pwdvd7S12BL5FaOP20EGYesN73k, USDC ASA 31566704, exact scheme

Any x402 v2 client handles this automatically:

js
import { wrapFetchWithPaymentFromConfig } from '@x402/fetch';import { ExactEvmScheme } from '@x402/evm';import { privateKeyToAccount } from 'viem/accounts';
const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {  schemes: [{ network: 'eip155:8453', client: new ExactEvmScheme(privateKeyToAccount(process.env.EVM_PRIVATE_KEY)) }],});const res = await fetchWithPayment('https://agentpay-lookup.agentpay-apis.workers.dev/lookup/v1/domain-report?domain=example.com');console.log(await res.json());

Full example for both networks: examples/x402-client.mjs.

Prepaid credits (fastest for repeated use)

GET https://agentpay.agentpay-apis.workers.dev/credits/buy?usd=5 (paid once via x402) returns { "apiKey": "ak_…" }. Send Authorization: Bearer ak_… on any endpoint or MCP server. Failed calls are refunded automatically. Balance: GET /credits/balance. Algorand holders can also pay by transfer: examples/buy-credits.mjs.

Using the MCP servers

Remote MCP over Streamable HTTP. Listing tools is free; tool calls are paid via x402 (params._meta["x402/payment"], per the x402 MCP transport) or with a credits key header.
