SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

HTTP probing and basic fingerprinting for in-scope targets, enabling rapid validation of live services and initial characterization.

Core Features & Use Cases

  • Liveness checks: verify HTTP/HTTPS endpoints are reachable and responding.
  • Triage data collection: gather status codes, titles, redirects, headers, TLS information, and technology clues.
  • Output normalization: produce machine-readable results suitable for downstream processing and auditing.

Quick Start

Run httpx on your target list to validate live HTTP services and collect basic fingerprint data.

FAQPage Schema
How do I check if HTTP endpoints are live and gather status codes for a large target list?

HTTP probing validates liveness for large target lists by checking endpoint reachability. It collects status codes, titles, redirects, and headers, producing structured JSON output to rapidly characterize in-scope web services.

What web fingerprinting data is collected during authorized HTTP probing?

Web fingerprinting during HTTP probing gathers status codes, titles, redirects, headers, TLS information, and technology clues. This triage data characterizes live services and produces machine-readable output suitable for downstream processing and auditing.

Can I use httpx probing outputs for downstream security testing and automation?

Yes, HTTP probing produces structured, machine-readable output, preferably JSON. This output normalization allows you to seamlessly feed liveness checks and fingerprint data into downstream automation pipelines for authorized security testing.

Does HTTP probing require explicit authorization before scanning domains and hosts?

Yes, HTTP probing and fingerprinting strictly require explicit authorization before scanning domains, hosts, or URLs. The process relies on CLI tools to follow explicit authorization requirements and usage guidelines when validating live services.

What is the best way to normalize recon outputs from large target lists for auditing?

The best way to normalize recon outputs is running HTTP probing to validate live HTTP services. It produces structured, machine-readable JSON results from large target lists, making triage data like TLS information and technology clues suitable for auditing.
