# Domain OSINT, TLS Certificate & Security Headers Recon

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

Performs live OSINT on a domain, returning IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry details, and HTTP security header grades.

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-spy-agentdiet-dev-domain-osint-tls-certificate-security-5ff30e54
```

Example prompt: Can you run a full security recon on anthropic.com — check its DNS resolution for IPv4 and IPv6, pull the TLS certificate issuer and expiry, and grade its HTTP security headers?

## When to prefer this

Choose this endpoint when you need a quick, all-in-one security reconnaissance snapshot of a domain covering DNS, TLS, and HTTP security headers in a single call. Prefer it over manual lookups or separate tools when you want live data (not cached) and need to assess a domain's security posture rapidly — e.g. during due diligence, incident response, or competitive analysis. It is especially useful when you need TLS certificate expiry and issuer information combined with security header grading in one request.

## Known failure modes

- Domain does not exist or fails DNS resolution — returns error or empty DNS fields
- Domain has no TLS certificate (HTTP-only site) — TLS fields may be null or absent
- Connection timeout if the target domain is unreachable or rate-limiting
- Invalid domain format supplied — returns validation error
- Domain resolves but HTTPS connection refused — TLS data 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-spy.agentdiet.dev/v1/osint)

## Output

Returns live DNS resolution (IPv4/IPv6 addresses), TLS certificate details (issuer, expiry date, validity status), and an HTTP security headers assessment including presence and grade of headers like HSTS, CSP, X-Frame-Options, and an overall security grade for the domain.
