Domain OSINT, TLS Certificate & Security Headers Recon

Choose this endpoint when you need a quick, all-in-one passive recon snapshot of a domain covering DNS, TLS, and HTTP security posture — especially useful for security due diligence, certificate monitoring, or OSINT workflows. Prefer this over separate tools when you want DNS + TLS + security headers in a single call without stitching multiple APIs together.

• Domain does not exist or fails DNS resolution — returns error or empty DNS records
• Domain has no HTTPS/TLS — certificate fields may be null or absent
• Target host is unreachable or times out — may return partial results or timeout error
• Invalid domain format passed — returns validation error
• Rate limit or payment failure via x402 — returns 402 or 429 status
