Running httpx - ProjectDiscovery Documentation

For all of the flags and options available for httpx be sure to check out the Usage page. On this page we’ll share examples running httpx with specific flags and goals and the output you can expect from each.

If you have questions, reach out to us through Help.

Basic Examples

ASN Fingerprint

Use httpx with the -asn flag for ASN (Autonomous System Number) fingerprinting, an effective technique for mapping the network affiliations of various domains.

subfinder -d hackerone.com -silent | httpx -asn

ASN Input

Specify an autonomous system’s number (ASN) and httpx will fetch all ip addresses of that autonomous system and probe them

echo AS14421 | httpx -silent

https://216.101.17.248
https://216.101.17.249
https://216.101.17.250
https://216.101.17.251
https://216.101.17.252

CIDR Input

Run httpx with CIDR input (for example 173.0.84.0/24)

echo 173.0.84.0/24 | httpx -silent

https://173.0.84.29
https://173.0.84.43

https://173.0.84.13
https://173.0.84.6
https://173.0.84.16
https://173.0.84.34

Docker Run

Use Docker to run httpx in an isolated container. For example, by piping subdomain lists into the Docker container, you can seamlessly perform probing across multiple targets, harnessing the power of httpx without direct installation requirements.

cat sub_domains.txt | docker run -i projectdiscovery/httpx

Error Page Classifier and Filtering

The Error Page Classifier and Filtering feature aims to add intelligence to httpx by enabling httpx to classify and filter out common error pages returned by web applications. It is an enhancement geared towards reducing noise and helping focus on actual results. Using the -fep or -filter-error-page option creates a filtered error page in the file filtered_error_page.json in jsonline format.

httpx -l urls.txt -path /v1/api -fep

File/Path Bruteforce

Use httpx with the -path option for efficient File/Path Bruteforcing. This feature allows probing specific paths across multiple URLs, uncovering response codes and revealing potentially vulnerable or unsecured endpoints in web applications.

httpx -l urls.txt -path /v1/api -sc

JARM Fingerprint

Use httpx with the -jarm flag to leverage JARM fingerprinting, a specialized tool for active TLS server fingerprinting. This approach enables the identification and categorization of servers based on their TLS configurations, making it an effective method for detecting and analyzing diverse internet servers, including potential security threats.

Tool Chain

Combining httpx with other tools like subfinder can elevate your web reconnaissance. For example, pipe results from subfinder directly into ‘httpx’ to efficiently identify active web servers and their technologies across various subdomains of a given target.

subfinder -d hackerone.com -silent| httpx -title -tech-detect -status-code

UI Dashboard (PDCP Integration)

Configure API Key

To upload your assets to PDCP you will need to create a free API Key

Obtain API Key:
- Visit https://cloud.projectdiscovery.io
- Open the setting menu from the top right and select “API Key” to create your API Key
- Use the httpx -auth command, and enter your API key when prompted.

Configure Team (Optional)

If you want to upload the asset results to a team workspace instead of your personal workspace, you can configure the Team ID. You can use either the CLI option or the environment variable, depending on your preference.

Obtain Team ID:
- To obtain your Team ID, navigate to https://cloud.projectdiscovery.io/settings/team and copy the Team ID from the top right section.
CLI Option:
- Use the -tid or -team-id option to specify the team ID.
- Example: nuclei -tid XXXXXX -dashboard
ENV Variable:
- Set the PDCP_TEAM_ID environment variable to your team ID.
- Example: export PDCP_TEAM_ID=XXXXX

Either of these options is sufficient to configure the Team ID.

Run httpx with UI Dashboard

To run httpx and upload the results to the UI Dashboard:

$ chaos -d hackerone.com | httpx -dashboard

Expanded Examples

Using httpx as a library

httpx can be used as a library by creating an instance of the Option struct and populating it with the same options that would be specified via CLI. Once validated, the struct should be passed to a runner instance (to be closed at the end of the program) and the RunEnumeration method should be called.

A basic example of how to use httpx as a library is available in the GitHub examples folder.

Using httpx screenshot

Httpx includes support for taking a screenshot with -screenshot that gives users the ability to take screenshots of target URLs, pages, or endpoints along with the rendered DOM. This functionality enables a comprehensive view of the target’s visual content. Rendered DOM body is also included in json line output when -screenshot option is used with -json option. To use this feature, add the -screenshot flag to the httpx command. httpx -screenshot -u https://example.com

Screenshots are captured using a headless browser, and as a result httpx will be slower when using the -screenshot option.

Domain, Subdomain, and Path Support

The -screenshot option is versatile and can be used to capture screenshots for domains, subdomains, and even specific paths when used in conjunction with the -path option:

httpx -screenshot -u example.com
httpx -screenshot -u https://example.com/login
httpx -screenshot -path fuzz_path.txt -u https://example.com

Using with Other Tools

In the example below we’re providing subfinder output to the httpx screenshot.

subfinder -d example.com | httpx -screenshot

System Chrome Support

By default, httpx uses the go-rod library to install and manage Chrome for taking screenshots. However, if you prefer to use your locally installed system Chrome, add the -system-chrome flag:

httpx -screenshot -system-chrome -u https://example.com

Output Directory

Screenshots are stored in the output/screenshot directory by default. To specify a custom output directory, use the -srd option:

httpx -screenshot -srd /path/to/custom/directory -u https://example.com

Body Preview

Body preview shows first N characters of response. And strip html tags in response.

httpx -u https://example.com -silent -body-preview
https://example.com [Example Domain This domain is for use in illustrative examples in documents. You may use this domai]

httpx -u https://example.com -silent -body-preview=200 -strip=html
https://example.com [Example Domain This domain is for use in illustrative examples in documents. You may use this domain in literature without prior coordination or asking for permission. More information...]
