# 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-4af1213e
```

Example prompt: Can you run a full domain OSINT check on stripe.com — I want to see its DNS resolution, TLS certificate issuer and expiry date, and its HTTP security headers grade?

## When to prefer this

Choose this endpoint when you need a fast, single-call OSINT snapshot of a domain's DNS posture, TLS certificate health, and HTTP security header configuration — especially useful for security audits, third-party vendor assessments, or monitoring domain infrastructure changes. Prefer this over manual dig/curl workflows when you need structured, machine-readable output combining DNS + TLS + security headers in one call.

## Known failure modes

- Domain does not exist or fails DNS resolution — likely returns an error indicating the domain could not be resolved
- Domain has no HTTPS/TLS — TLS fields may be null or missing
- Domain blocks automated requests — HTTP security header inspection may time out or return incomplete data
- Invalid domain input (empty string, malformed) — returns validation error
- Network timeout reaching the target domain — may return partial results or a timeout 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-intel.agentdiet.dev/v1/whois-lookup)

## Output

Returns a structured object containing live IPv4 and IPv6 DNS resolution results, TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security headers grade with details on which headers are present or missing.
