Domain OSINT, TLS Certificate & Security Headers Recon

Choose this endpoint when you need a quick, all-in-one security reconnaissance snapshot of a domain covering DNS, TLS, and HTTP headers in a single call. It is ideal for OSINT workflows, vendor security assessments, phishing domain investigations, or pre-integration security checks. Prefer this over manual nslookup, SSL Labs, or SecurityHeaders.io tools when you need programmatic access to combined results at low cost ($0.01/call).

• Domain does not exist or fails DNS resolution — likely returns an error or empty DNS records
• Domain has no HTTPS endpoint — TLS certificate fields may be absent or null
• Network timeout reaching the target domain — may return partial or error response
• Invalid domain format provided — likely returns a validation error
• Domain uses non-standard ports — inspection may default to port 443 and miss alternate configurations
