# 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, and HTTP security header grading for a given domain name.

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-b1f3b029
```

Example prompt: Can you run a full domain OSINT check on stripe.com — I need to see its DNS resolution (both IPv4 and IPv6), TLS certificate issuer and expiry date, and how it scores on HTTP security headers?

## When to prefer this

Use this endpoint when you need a quick, live OSINT snapshot of a domain's network and security posture — specifically DNS resolution, TLS certificate health, and HTTP security header grades — without setting up your own scanning infrastructure. Ideal for security due diligence, vendor assessments, competitive reconnaissance, or pre-deployment audits where a single-call, pay-per-use model is preferable to running your own tools.

## Known failure modes

- Domain does not exist or fails DNS resolution — returns empty or error for DNS fields
- Domain has no HTTPS endpoint — TLS certificate fields unavailable
- Target domain blocks or rate-limits the probe — incomplete or timeout response
- Malformed domain input — validation error returned
- Domain resolves but has no security headers — security grade reflects absence

## 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/asn-lookup)

## Output

Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security grade reflecting the presence and quality of security headers such as HSTS, CSP, X-Frame-Options, and others.
