A small python script for pushbullet interaction from the command line. Very much based on the weebullet source, with some modifications.

push.py

#!/bin/python2
import sys
import json
import requests

apikey = "REDACTED"

def send_push(title, body):
    print "Sending push.  Title: [%s], body: [%s]\n" % (title, body)
    apiurl = "https://api.pushbullet.com/v2/pushes"
    timeout = 20000  # arbitary value
    if len(title) is not 0 or len(body) is not 0:
        payload = json.dumps({'type':'note', 'title':title, 'body':body.encode('utf-8')})
        headers = {'Access-Token': apikey, 'Content-Type': 'application/json'}
        try: 
        	r = requests.post(apiurl, data=payload, headers=headers, timeout=timeout)
        	if r.status_code is 401 or r.status_code is 403:
        		print "Invalid API token: %s\n" % apikey
        	if r.status_code is not 200:
        		print "Error sending to pushbullet: %s - %s - %s\n" % (apiurl, r.status_code, body)
        except Exception, e:
        	raise e

	send_push("Push from the command line!", pushval)

if __name__ == '__main__':
