# 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.

Performs live DNS resolution (IPv4/IPv6), TLS certificate inspection, and HTTP security header grading for a 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-119736ea
```

Example prompt: Can you run a full DNS, TLS certificate, and HTTP security header recon on anthropic.com — I want to know the IPv4/IPv6 addresses, who issued the SSL cert and when it expires, and how they score on security headers?

## When to prefer this

Choose this endpoint when you need a combined, single-call OSINT snapshot of a domain's DNS infrastructure, SSL/TLS certificate health, and HTTP security header posture — especially useful for security due diligence, vendor assessments, or competitive intelligence workflows where you want DNS + TLS + headers in one response rather than calling separate tools.

## Known failure modes

- Domain does not exist or fails DNS resolution — returns error or empty DNS result
- Domain has no TLS certificate (HTTP-only) — TLS fields absent or error returned
- Network timeout reaching the target domain — partial or failed response
- Invalid domain format provided — validation error returned
- Rate limiting or payment failure via x402 — HTTP 402 or 429 response

## 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/dns-whois-tls-recon)

## Output

Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, chain info), and an HTTP security header grade/analysis for the target domain, enabling infrastructure OSINT and security posture assessment.
