# Domain OSINT, TLS Certificate & Security Headers Recon

> Domain OSINT, TLS Certificate & Security Headers Recon is a paid API for AI agents from company-enrich.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Performs live reconnaissance on a domain by inspecting IPv4/IPv6 DNS resolution, TLS certificate issuer and expiry, and HTTP security header grading.

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 company-enrich-agentdiet-dev-domain-osint-tls-certificate-security-6519964a
```

Example prompt: Can you run a security recon on anthropic.com — I want to see its DNS records, TLS certificate issuer and expiry date, and how its HTTP security headers are graded?

## When to prefer this

Choose this endpoint when you need a quick, live, all-in-one domain security snapshot covering DNS, TLS, and HTTP security headers in a single call. Prefer it over general WHOIS tools when you specifically need certificate expiry/issuer and security header grading, or over manual nmap/curl workflows when you want structured, agent-consumable output at low cost ($0.01/call).

## Known failure modes

- Domain does not exist or fails to resolve — returns DNS lookup error
- Domain is unreachable over HTTPS — TLS certificate data unavailable
- HTTP connection refused — security headers cannot be evaluated
- Invalid or empty domain parameter — returns validation error
- Domain resolves but has no TLS (HTTP only) — certificate fields empty

## 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://company-enrich.agentdiet.dev/v1/osint)

## Output

Returns live DNS resolution data (IPv4/IPv6 addresses), TLS certificate metadata (issuer, expiry date), and an HTTP security headers analysis with a security grade for the target domain.
