Command Reference

The API's CLI currently supports the following launch-arguments:

• --https Attempt to serve the API via HTTPS (default is false), searching for certificates as specified in the current environment.
• -p, --port Port in which the API will listen for requests. Values must be in range 1-65535 (default is 8080).
• -s, --silent Enable silent mode in order not to log any output to console (default is false)
• -v, --verbose Show additional logging information (use cumulative times for additional info, like: -vvv)
• --version Print the version of the program
• --help Print the help menu

Verbosity levels

When using the -v, --verbose CLI argument, the following logging messages are shown on console at each time:

• No verbose argument ERROR level messages
• -v WARN level messages and upwards
• -vv INFO level messages and upwards (includes client connections and requests)
• -vvv DEBUG level messages and upwards

The verbosity parameter will be ignored whenever -s, --silent is in use

• -Djdk.tls.client.protocols=TLSv1.2
