# Domain Intelligence API
[](https://domain-intelligence.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Domain intelligence in one call: WHOIS, DNS records, SSL certificate, domain age. Essential for due diligence and security audits. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) 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`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `domain_lookup_intelligence` | GET | `/api/lookup` | $0.012 | Get comprehensive domain intelligence (WHOIS + DNS + SSL) |
| `domain_lookup_intelligence` | POST | `/api/lookup` | $0.012 | Get comprehensive domain intelligence (WHOIS + DNS + SSL) (POST variant) |
### `domain_lookup_intelligence`
Use this when you need comprehensive domain intelligence -- WHOIS, DNS, and SSL data in a single call. Returns structured JSON with full domain profile.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `domain` | string | yes | Domain to lookup (e.g. example.com) |
Example response:
```json
{"whois":{"registrar":"Cloudflare","createdDate":"2010-01-15","expiryDate":"2027-01-15","nameservers":["ns1.cloudflare.com"]},"dns":{"a":["104.26.10.1"],"mx":[{"priority":10,"exchange":"mx.example.com"}]},"ssl":{"issuer":"Let's Encrypt","daysRemaining":45},"domainAge":5932}
```
**When to use**: domain purchases, security audits, phishing investigations, or due diligence on vendors. Essential for checking domain legitimacy, SSL health, and DNS configuration.
**Not for**: company data (use `company_enrich_from_domain`), IP geolocation (use `ip_lookup_geolocation`), website content (use `web_scrape_to_markdown`), email deliverability (use `email_audit_deliverability`).
### `domain_lookup_intelligence`
Use this when you need comprehensive domain intelligence -- WHOIS, DNS, and SSL data in a single call. Returns structured JSON with full domain profile. POST variant of domain_lookup_intelligence -- same params passed as JSON body instead of query string.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
