# Domain OSINT, TLS Certificate & Security Headers Recon

> Domain OSINT, TLS Certificate & Security Headers Recon is a paid API for AI agents from shopify-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Performs live DNS resolution (IPv4/IPv6), TLS certificate inspection (issuer/expiry), and HTTP security header grading for a given domain.

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 shopify-intel-agentdiet-dev-domain-osint-tls-certificate-security-40a007b4
```

Example prompt: Can you run a full security recon on anthropic.com — I want to see its DNS resolution (IPv4 and IPv6), TLS certificate issuer and expiry date, and its HTTP security header grade?

## When to prefer this

Use this endpoint when you need a combined, real-time OSINT snapshot covering DNS, TLS, and HTTP security headers in a single call — ideal for security due diligence, vendor assessments, certificate expiry monitoring, and competitive web security analysis. Prefer this over standalone WHOIS or certificate transparency tools when you need live, multi-signal domain intelligence in one request at low cost.

## Known failure modes

- Domain does not exist or fails to resolve — returns DNS lookup failure
- Domain has no TLS certificate or HTTPS endpoint — TLS fields may be null or absent
- Invalid domain input (empty string, malformed) — validation error returned
- Domain is unreachable or times out — connection timeout error
- Payment not completed (HTTP 402) — request blocked until x402 payment is fulfilled

## How this service works

Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-intel.agentdiet.dev/v1/whois-lookup)

## Output

Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity), and an HTTP security header grade reflecting the presence or absence of headers like HSTS, CSP, X-Frame-Options, and similar security controls.
