# 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 DNS resolution (IPv4/IPv6), TLS certificate inspection (issuer, expiry), and HTTP security header grading for any target 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-spy-agentdiet-dev-domain-osint-tls-certificate-security-aae6cfa4
```

Example prompt: Can you run a full DNS, TLS certificate, and HTTP security header audit on stripe.com — I want to know who issued the cert, when it expires, the resolved IPs, and what security grade the headers get?

## When to prefer this

Choose this endpoint when you need live, real-time DNS, TLS, and HTTP security header data for a single domain in one call — ideal for security reconnaissance, due diligence on vendor or acquisition targets, monitoring certificate expiry, or benchmarking competitor security posture. Prefer this over manual nmap/curl workflows or separate DNS/SSL checker tools when you need a unified OSINT snapshot with a security grade in a single API call.

## Known failure modes

- Domain does not exist or fails DNS resolution — empty or error response
- Domain has no HTTPS endpoint — TLS certificate data absent
- Network timeout reaching the target domain — partial or null results
- Invalid domain format provided — validation error
- Domain is unreachable from probe infrastructure — connectivity error

## 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/ssl-audit)

## Output

Returns live IPv4 and IPv6 addresses resolved for the domain, TLS certificate metadata (issuer, validity dates, expiry), and an HTTP security headers analysis including a security grade, giving a full OSINT snapshot of the domain's network and TLS posture.
