WHOIS, DNS records, SSL certificate data for any domain in one call. x402.

Overview

AI-generated overview

Remote MCP endpoint that returns WHOIS, DNS and SSL certificate data for a domain in one paid call.

What you can do
  • Look up a domain's WHOIS registration details, DNS records and SSL certificate status in a single call, returned as structured JSON with a computed domain age.
  • The same lookup is offered as a GET query and a POST JSON-body variant.
When to use it
Useful when checking domain legitimacy, SSL health or DNS configuration during domain purchases, vendor due diligence, security audits or phishing investigations.
Requirements
A remote SSE endpoint; no local install, account or API key. Each call is paid per use in USDC on the Base L2 network through the x402 protocol, so an x402-capable client with a funded wallet is needed to complete the payment challenge.
Before you install
Every lookup costs money (listed at $0.012 per call) and is settled in USDC on Base, so a wallet with funds is exposed to the service. Payment is handled by third-party facilitators (Coinbase CDP, PayAI). The domain you query is sent to an external API.

Installation

In SourceWeft

  1. Open Domain Intelligence API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fdomain-intelligence/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Domain Intelligence API

[MCP Server] [x402] [License: MIT]

Domain intelligence in one call: WHOIS, DNS records, SSL certificate, domain age. Essential for due diligence and security audits. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "domain-intelligence": {      "url": "https://domain-intelligence.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://domain-intelligence.api.klymax402.com/api/lookup?domain=..."# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
