# 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, 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-spy-agentdiet-dev-domain-osint-tls-certificate-security-ed15f229
```

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

## When to prefer this

Choose this endpoint when you need a combined DNS + TLS + HTTP security header inspection in a single call, particularly for security recon, vendor due diligence, domain OSINT, or infrastructure auditing workflows. Prefer it over generic whois or certificate transparency tools when you want a live, real-time grade rather than historical data.

## Known failure modes

- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- Domain has no HTTPS/TLS — certificate fields absent or error returned
- Target domain blocks automated probes or returns non-standard responses
- Invalid or malformed domain input — validation error
- Upstream DNS or TLS timeout — may return partial data or 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-spy.agentdiet.dev/v1/tls-scanner)

## Output

Returns live DNS resolution data (IPv4 and IPv6 addresses), TLS certificate details (issuer, expiry date, validity), and an HTTP security header grade/analysis for the specified domain.
