A simple python library for getting caller ID name information using the opencnam API.

Project description

A simple python library for getting caller ID name information.

This library uses [opencnam]( “opencnam”) as a backend.

## Installation

Install from PyPi using [pip](, a package manager for Python.

$ pip install opencnam

Don’t have pip installed? Try installing it, by running this from the command line:

$ curl | python

Or, you can [download the source code (ZIP)]( “opencnam source code”) for opencnam, and then run:

$ python install

You may need to run the above commands with sudo.

## Usage

Using python-opencnam is easy:

from opencnam import Phone

phone = Phone('2024561111')
print phone.number, phone.cnam

The main object, Phone, defined in the opencnam module accepts a phone number as input, and (behind the scenes) queries the [opencnam]( “opencnam”) API to set the Phone.cnam attribute.

To make things insanely easy, python-opencnam transparently handles phone number validation–so you can create a Phone object using any phone number you can possibly imagine, as long as it can be cleaned up into a valid, 10-digit, US phone number.

For example:

from opencnam import Phone

phone = Phone('+1 (818)-217 \\\\9229')
assert phone.number == '8182179229'

The way the number cleaning algorithm works is:

  • Remove all non-integer characters.

  • Grab the last 10 digts of the string.

  • Make sure those 10 digits are a valid US phone number.

So you can go crazy with input, and not worry about getting an opencnam.InvalidPhoneNumberError exception unless the phone number cannot be made valid.

## API Authentication

If you’ve got an account on [opencnam]( “opencnam”), you can use your API credentials with python-opencnam. This will allow you to make an unlimited amount of API queries (since paid users have no limits).

To specify your API credentials, just pass them into the Phone constructor, like so:

from opencnam import Phone

phone = Phone(‘+18182179229’, api_user=’username’, api_key=’blah’)

Assuming you’ve specifid both the api_user and api_key params, python-opencnam will use your credentials and you’ll be running in no time!

## Limits

The [opencnam]( “opencnam”) API we use as a backend limits you to no more than 60 requests per minute (using their free tier).
