# Domain OSINT, TLS Certificate & Security Headers Recon

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

Performs live reconnaissance on a domain including IPv4/IPv6 DNS resolution, TLS certificate issuer and expiry details, 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 alpha-stream-agentdiet-dev-domain-osint-tls-certificate-security-8a819022
```

Example prompt: Can you run a full domain security recon on openai.com — I want to see its DNS resolution (IPv4 and IPv6), TLS certificate issuer and expiry, and HTTP security header grade?

## When to prefer this

Choose this endpoint when you need a combined DNS + TLS + HTTP security header snapshot for a domain in a single call, especially for OSINT workflows, security audits, vendor due diligence, or certificate expiry monitoring. It is ideal when you want structured recon data without standing up your own scanning infrastructure.

## Known failure modes

- Domain does not exist or is unresolvable — DNS lookup fails with NXDOMAIN
- Domain has no TLS/HTTPS — certificate data unavailable
- Request times out due to slow DNS or unresponsive target server
- Invalid domain string format provided
- Domain resolves but HTTP server is unreachable for header inspection

## 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://alpha-stream.agentdiet.dev/v1/dns-whois-tls-recon)

## Output

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