# 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

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-279e52fd
```

Example prompt: Can you pull the DNS records, TLS certificate info, and HTTP security header grade for anthropic.com so I can assess its security posture?

## When to prefer this

Choose this endpoint when you need a quick, combined OSINT snapshot of a domain's DNS, TLS, and HTTP security posture in a single call, rather than running separate DNS lookup, certificate transparency log, and security header checker tools individually. Ideal for vendor due diligence, competitive recon, or automated security monitoring pipelines.

## Known failure modes

- Domain does not exist or fails DNS resolution — may return empty or error response
- Domain is unreachable at time of query — TLS/header data unavailable
- Invalid or malformed domain string — validation error
- TLS certificate missing or expired — may return partial data
- Network timeout reaching the target domain

## 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/cert-transparency)

## Output

Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate details (issuer, expiry date), and an HTTP security header grade/assessment for the queried domain.
