A script that lets a raspberry pi tell Pinboard where it is.

FindAPi.py

import socket
import requests
import sys
import os

name = socket.gethostname()
AUTH_TOKEN = 'YOUR_API_KEY_HERE'
PINBOARD_URL = 'https://api.pinboard.in/v1/posts/add'
FILE_NAME = './ipAddress'


def get_ip():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    try:
        # doesn't even have to be reachable
        s.connect(('10.255.255.255', 0))
        ip = s.getsockname()[0]
    except:
        ip = '127.0.0.1'
    finally:
        s.close()
    return ip


def read_ip():
    new_ip = get_ip()

    if os.path.isfile(FILE_NAME):
        file = open(FILE_NAME, 'r+')
        ip = file.read()
    else:
        file = open(FILE_NAME, 'w')
        ip = 'empty'

    if ip != new_ip:
        file.write(new_ip)
        pin_it(new_ip)

        
def pin_it(ip):
    params = {
        'url': 'http://' + ip
        , 'description': name
        , 'tags': 'r_pi find_a_pi'
        , 'replace': 'yes'
        , 'shared': 'no'
        , 'toread': 'yes'
        , 'extended': 'This is the ip address for ' + name
        , 'auth_token': AUTH_TOKEN}
    r = requests.get(PINBOARD_URL, params=params)

    if r.status_code == requests.codes.ok:
        sys.exit()
    else:
        sys.exit(r.status_code)


read_ip()

This is quick and dirty and could be much better, but it runs quickly and does what I need it to do. If you have a Pinboard account and some Raspberry Pis that you want to track this is a good way to do it.
