httpx

Use ProjectDiscovery httpx for authorized HTTP probing of in-scope hosts and URLs. This is the ProjectDiscovery CLI, not the Python httpx library.

Use When

• A domain, host, URL, or recon output list needs HTTP/HTTPS liveness validation.
• Results from DNS, nmap, or user-provided target lists need status code, title, redirect, header, TLS, or technology triage.
• A large target list needs normalized output before deeper browser review, fingerprinting, or vulnerability validation.

Usage Rules

• Work only on explicitly authorized targets.
• Before constructing commands, run the installed help and use it as the source of truth:

httpx -help

• Prefer file or stdin input for target lists, and keep batches bounded.
• Prefer JSON output when results will be parsed with jq or consumed by another tool.
• Use silent/no-color output modes when piping to avoid mixing progress text with data.
• Save large outputs to files rather than streaming them into the conversation.
• Treat detected technologies, titles, redirects, and TLS observations as triage signals; validate important claims with response evidence, browser inspection, observer_ward, or targeted follow-up.
• Do not use update, cloud/dashboard upload, screenshot, headless browser, or high-concurrency modes unless the user explicitly asks and the scope permits it.
