keepaAPI 0.14.2

Interfaces with keepa.com

Python module to interface to Keepa to query for Amazon product information and history.

Requirements

Module is compatible with Python 2 and 3. keepaAPI requires:

  • numpy
  • requests

Product history can be plotted from the raw data when matplotlib is installed.

Interfacing with the keepaAPI requires an accesskey and a monthly subscription from https://keepa.com/#!api

Installation

Module can be installed from PyPi using pip install keepaAPI

Source code can also be downloaded from GitHub and installed using python setup.py install or pip install .

Brief Example

import keepaAPI
accesskey = 'XXXXXXXXXXXXXXXX' # enter real access key here
api = keepaAPI.API(accesskey)

# Single ASIN query
products = api.ProductQuery('059035342X') # returns list of product data

# Plot result (requires matplotlib)
keepaAPI.PlotProduct(products[0])

Detailed Example

Import interface and establish connection to server

import keepaAPI
accesskey = 'XXXXXXXXXXXXXXXX' # enter real access key here
api = keepaAPI.API(accesskey)

Single ASIN query

products = api.ProductQuery('059035342X')

# See help(api.ProductQuery) for available options when querying the API

Multiple ASIN query from List

asins = ['0022841350', '0022841369', '0022841369', '0022841369']
products = api.ProductQuery(asins)

Multiple ASIN query from numpy array

asins = np.asarray(['0022841350', '0022841369', '0022841369', '0022841369'])
products = api.ProductQuery(asins)

Products is a list of product data with one entry per successful result from the Keepa server. Each entry is a dictionary containing the same product data available from Amazon.

# Available keys
print(products[0].keys())

# Print ASIN and title
print('ASIN is ' + products[0]['asin'])
print('Title is ' + products[0]['title'])

The raw data is contained within each product result. Raw data is stored as a dictonary with each key paired with its associated time history.

# Access new price history and associated time data
newprice = products[0]['data']['NEW']
newpricetime = products[0]['data']['NEW_time']

# Can be plotted with matplotlib using:
import matplotlib.pyplot as plt
plt.step(newpricetime, newprice, where='pre')

# Keys can be listed by
print(products[0]['data'].keys())

The product history can also be plotted from the module if matplotlib is installed

keepaAPI.PlotProduct(products[0])
