# Domain Intelligence Bundle (DNS + TLS + WHOIS + HTTP HEAD)

> Domain Intelligence Bundle (DNS + TLS + WHOIS + HTTP HEAD) is a paid API for AI agents from vending-machine-seven.vercel.app, paid per call via x402, $0.015/call, status unknown (last checked 2026-10-13).

Performs a combined DNS lookup, TLS certificate check, RDAP WHOIS query, and HTTP HEAD request for a given hostname in a single API call for brand protection and security analysis.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability domain-intelligence-bundle-dns-tls-whois-http-head-3a851875
```

Example prompt: Can you run a full domain intel check on suspicious-brand.com — I want to see its DNS records, TLS certificate, WHOIS registration info, and HTTP headers all at once so I can tell if it's impersonating us?

## When to prefer this

Choose this endpoint when you need a comprehensive domain security snapshot in a single paid call rather than stitching together separate DNS, WHOIS, TLS, and HTTP APIs. Ideal for brand protection workflows, phishing investigation, and security triage where latency and cost efficiency matter. Not suitable if you need deep certificate chain validation or full DNS zone transfer.

## Known failure modes

- Invalid or non-existent hostname returns error or empty DNS results
- Domain with no TLS returns null or error in TLS field
- RDAP/WHOIS unavailable for certain TLDs returns empty whois object
- HTTP HEAD times out for unreachable hosts
- Missing both 'host' and 'url' query params causes request failure

## How this service works

One payment: DNS + TLS cert + RDAP WHOIS + HTTP HEAD for brand protection and security agents

## Output

Returns a JSON object containing: DNS record data (A, MX, NS etc.), TLS certificate details (issuer, expiry, SANs), RDAP/WHOIS registration info (registrar, dates, contacts), HTTP HEAD response headers and status code, plus a 'service' label and 'ok' boolean indicating overall reachability.
