Options
    -i <URL>: The URL the script should use when calling an endpoint
    -f <fingerprint>: a hex string of the SHA1 hash of the certificate to use when signing.
    -t: use self signing. If this option is specified, the script should allow a web API request that uses an untrusted certificate.
