Possible to create irules via icontrol REST API?

I have been playing with some python code with this. This creates an irule, lists it, then deletes it.

Main:

if __name__ == "__main__":
    import requests, time, json

    b = requests.session()
    b.auth = ('admin', 'admin')
    b.verify = False
    b.headers.update({'Content-Type' : 'application/json'})

    b_url_base = 'https://192.168.6.5/mgmt/tm'

    mycode = 'priority 100\nwhen CLIENT_ACCEPTED {\n\tlog local0. \"test\"\n}'
    create_rule(b, 'testme2', mycode)

    rule = get_rule(b, 'testme2')
    print rule.text

    delete_rule(b, 'testme2')

Functions:

def get_ruleset(bigip):
    rules = bigip.get('%s/ltm/rule/' % b_url_base)
    return rules

def get_rule(bigip, name):
    rule = bigip.get('%s/ltm/rule/%s' % (b_url_base, name))
    return rule

def delete_rule(bigip, name):
    bigip.delete('%s/ltm/rule/%s' % (b_url_base, name))

def create_rule(bigip, name, code):
    payload = {}
    payload['kind'] = 'tm:ltm:rule:rulestate'
    payload['name'] = name
    payload['fullPath'] = name
    payload['apiAnonymous'] = code

    bigip.post('%s/ltm/rule/' % b_url_base, data=json.dumps(payload))
    print 'Rule %s created...' % name
