Gameprices

Command line tool for alerting price drops in the Sony PlayStation Network (PSN) and the Nintendo Eshop.

Description

The Sony Entertainment Network (SEN) uses CIDs to identify items in its catalogue. In order to alert you on the desired price of an SEN you need the CID. Use your Browser (cid GET parameter in URL) or this script (--query) to retrieve the CID.

In order to check the price of an item. You need a store identifier. These store identifiers are known to work:

• DE/de (Germany)
• GB/en (Great Britain)
• US/en (United States)
• SE/en (Sweden)
• JP/jp (Japan)

Prices are always in the local currency. Therefore, it is € for DE/de and £ for GB/en. Additionally, prices are those for PlayStation Plus users.

The Eshop implementation lacks unique identifiers, because the Eshop does not support searching for unique identifiers. Therefore, an identifier is constructed containing the game name.

Retrieving UTF-8 encoded output on terminals

You may have to tell Python that your terminal is capable of dealing with UTF-8 outputs. Some PSN items are annotated with trademark, copyright or foreign language specific symbols. To do so set export PYTHONIOENCODING=utf-8 in your terminal window.

Example

You may run this script with the following command line variants:

Mail alerting - Get a mail when alerts have been met

With psnmailalert you may set alerts for price drops in the alerts.csv file. The first value is the CID for the item, the second is the price to be matched in order to alert you by mail, and the second value is the store to search in. You may mix stores in the alerts.csv. After a price has been matched, the alert is removed from alerts.csv. You will not get any further alerts for that item.

P0001-NPEJ00305_00-B000000000001030,19.00,DE/de
P0001-NPEJ00305_00-B000000000001030,19.00,DE/de
EP0102-CUSA02521_00-MEGAMANLEGACY000,7.00
UP0102-CUSA02516_00-MEGAMANLEGACY000,7.00,US/en
P0101-ULES01372_00-GPCMETALGE000001,10.00,DE/de

If the store value is left blank, the script tries to extract the store from the beginning character of the CID.

In order to receive mails you have to set your account settings in the file mailconfig.json. See mailconfig.json_example for an example config.

To run psnmailalert, just type:

psnmailalert

Example mail

Searching for the CID of an item

Define the name of a game and the store.

psncli --query "metal gear solid peace walker" --store DE/de

You will get a result containing one to many search results with the CID. The first output of each search line is the CID, the second the name, the third the supported systems and the last is a description of the item type in the local store language. It is "Vollversion" here which means "full version" in German.

Use the --json flag to get the same output as JSON.

eshopcli --json -q "Dynasty Warriors 8 Xtreme Legends"
[
  {
    "id": "1490013",
    "name": "DYNASTY WARRIORS 8: Xtreme Legends Definitive Edition",
    "type": "GAME",
    "prices": [
      {
        "price": 39.99,
        "currency": "",
        "type": "OFFER"
      }
    ],
    "platforms": [
      "Nintendo Switch"
    ]
  },
...

Check if desired price has been met

The price is in local currency. As exit statuses render the outcome of the alert, you may send mails or desktop notifications with && or ||. In this example, there is a string printed to the console.

psncli --id EP0101-ULES01372_00-GPCMETALGE000001 --store DE/de --price 15.00 &&
echo "Price matched, let's buy Metal Gear Solid PW"
