Domain OSINT, TLS Certificate & Security Headers Recon

Choose this endpoint when you need a lightweight, combined OSINT snapshot of a domain covering DNS, TLS, and HTTP security headers in a single call, especially for vendor due diligence, security auditing, or certificate expiry monitoring. Prefer this over dedicated tools when you want a rapid single-call reconnaissance rather than deep vulnerability scanning or full port enumeration.

• Domain does not exist or fails to resolve — returns DNS lookup error
• TLS certificate is missing or self-signed — may return partial data
• Domain is unreachable or times out — returns connectivity error
• Invalid domain format supplied — returns validation error
• Non-existent or parked domain with no HTTP headers to inspect — returns partial result
