IGetPrices Returns price information for all priced items

Requirements

  • You will need to register for a backpack.tf API key to use this service. Get your key.

Limitations

  • You may only request the prices once every 5 minutes. If you request before 5 minutes has passed since your last request, you will receive a 403 error. You should be caching these prices on your side, a 1 hour delay before fetching new prices should be sufficient for anyone's needs.

Example

  • http://backpack.tf/api/IGetPrices/v3/?format=json&key=apikey

Parameters

  • key (required)
    • Your backpack.tf API key.
  • format (optional)
    • Output format. json (default), jsonp (requires callback query string) or vdf.
  • names (optional)
    • If you set names to 1, the API will add item names to the returned output.
