Simple Python library to use the SCANOSS APIs.

Project description

SCANOSS Python Package

The SCANOSS python package provides a simple easy to consume library for interacting with SCANOSS APIs/Engine.


To install (from, please run:

pip3 install scanoss

To upgrade an existing installation please run:

pip3 install --upgrade scanoss


Alternatively, there is a docker image of the compiled package. It can be found here. Details of how to run it can be found here.


The package can be run from the command line, or consumed from another Python script.

CLI Usage

The Python package manager (pip), will register the following command during installation:


It is also possible to launch it using:

python3 -m scanoss.cli

Running the bare command will list the available sub-commands:

> scanoss-py

usage: scanoss-py [-h] {version,ver,scan,sc,fingerprint,fp,wfp,dependencies,dp,dep} ...

SCANOSS Python CLI. Ver: 0.9.0, License: MIT

optional arguments:
  -h, --help            show this help message and exit

Sub Commands:
  valid subcommands

                        sub-command help
    version (ver)       SCANOSS version
    scan (sc)           Scan source code
    fingerprint (fp, wfp)
                        Fingerprint source code
    dependencies (dp, dep)
                        Scan source code for dependencies

From there it is possible to scan a source code folder:

> scanoss-py scan -o scan-output.json <source-folder>

Scanning for Dependencies

The SCANOSS CLI supports dependency decoration. In order for this to work, it requires the installation of scancode:

pip install scancode-toolkit

Dependencies can then be decorated by adding the --dependencies option to the scanner:

> scanoss-py scan --dependencies -o scan-output.json <source-folder>

Package Usage

The scanoss package can also be used in other Python projects/scripts. A good example of how to consume it can be found here.

In general the easiest way to consume it is to import the required module as follows:

from scanoss.scanner import Scanner

def main():
    scanner = Scanner()
    scanner.scan_folder( '.' )
if __name__ == "__main__":

Scanning URL and API Key

By Default, scanoss uses the API URL endpoint for SCANOSS OSS KB: This API does not require an API key.

These values can be changed from the command line using:

> scanoss-py scan --apiurl <URL> --key <KEY>

From code, it would look like this:

from scanoss.scanner import Scanner

def main():
    scanner = Scanner(url='new-url', api_key='key')
    scanner.scan_folder( '.' )
if __name__ == "__main__":


Python 3.7 or higher.
