# 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-214ac42b
```

Example prompt: Can you run a full DNS, TLS certificate, and HTTP security header audit on anthropic.com — I want to see the certificate issuer, expiry date, IPv4/IPv6 addresses, and what security headers they have?

## When to prefer this

Choose this endpoint when you need a quick, all-in-one OSINT snapshot of a domain's DNS, TLS, and HTTP security posture without setting up separate tooling. It is ideal for security audits, competitive reconnaissance, pre-launch checks, or certificate expiry monitoring where you want live data in a single call rather than stitching together separate DNS, SSL, and header-inspection tools.

## Known failure modes

- Domain does not exist or fails DNS resolution — empty or error response
- Domain is reachable but has no TLS certificate (HTTP-only) — TLS fields absent or null
- Firewall or rate limiting blocks the probe — timeout or 4xx error
- Malformed domain input — validation error returned
- TLS handshake failure — certificate details may be partially unavailable

## 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/ssl-audit)

## Output

Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity), and an HTTP security header assessment including which security headers are present and an overall security grade for the domain.
