# 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.

## Facts

- Price: $0.01/call
- Payment: MPP
- Status: unknown
- Last checked: 2026-10-21

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-325fb9e4
```

Example prompt: Can you scan openai.com for me — I want to see its DNS resolution (both IPv4 and IPv6), who issued its TLS certificate and when it expires, and what HTTP security grade the server gets?

## When to prefer this

Use this endpoint when you need a fast, single-call snapshot of a domain's DNS, TLS certificate, and HTTP security posture without running full vulnerability scans. Ideal for OSINT workflows, vendor risk checks, certificate expiry monitoring, and security benchmarking where a lightweight live probe is sufficient over a deep scanner.

## Known failure modes

- Domain does not exist or fails DNS resolution — returns error or empty DNS result
- TLS certificate absent or self-signed — may return limited cert data
- Domain blocks automated probes — may return timeout or connection refused
- Invalid domain string input — returns validation error
- Transient network issues causing incomplete scan results

## 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/tls-scanner)

## Output

Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate details (issuer, validity dates, expiry status), and an HTTP security header grade reflecting the server's configuration quality.
