Installation

First, you’ll need to install trundlerpy from PyPI.

pip3 install trundlerpy

If you want to keep up to date with the latest package developments, you can also install trundlerpy directly from GitHub.

pip3 install git+https://github.com/datawookie/trundlerpy

Authenticating

It’s a good idea to store your API key in an environment variable rather than hard-coded into a script.

import os

trundler_key = os.getenv('TRUNDLER_KEY')

Now, import the package and set your API key.

from trundlerpy import Trundler

# Set the API Key
tr = Trundler(key = trundler_key)

Retailers

You can use retailer() to return a Pandas DataFrame of retailers.

# Get retailers
retailer = tr.retailer()

# View the first 10 retailers
retailer.head(10)[["retailer_id", "retailer", "retailer_url", "currency"]]

Products

The retailer_products() method yields a DataFrame with the products for a specific retailer, where each product is assigned a name, brand, model, SKU and barcode (if available).

# View first 5 products at a specific retailer
tr.retailer_products(5)[["product_id", "product", "sku"]].head(5)

   product_id                                     product            sku
0     3389739   Filigree DD+ Underwire Bra - BLACK / 44/E  6009217012503

4     3389743  Filigree DD+ Underwire Bra - BLACK / 38/DD  6009217012381

Products can also be filtered by name and brand.

product = tr.retailer_products(5, product = "coffee", brand = "nespresso").head(5)

To get details on a specific product, use the product_details() method and the product ID.

# Get details on an specific product
tr.product(711497)[["product_id", "product", "sku"]]

   product_id                                       product            sku
0      711497  Instant Coffee Café Gold Italian Sachets 50g  6009204582774

Prices

Finally, you can use product_prices() to get the price history for a particular product using its product ID.

# Get the price history for a specific product
tr.product_prices(711497).head(10)

   product_id                       time  price price_promotion available
