PCGS Public API

Display Coin Details in Your Application

Our REST API methods are accessed by HTTPs and allow you to interact with common PCGS coin data using HTTP response codes to indicate errors. Successful response content is available in JSON or XML formatting. For security, we use OAuth 2 with password grant to obtain an access token for you using your PCGS login credentials. Remember to never expose your credentials in any public website's client-side code.

Currently, the PCGS Public API supports the following ways to get data from CoinFacts or Auction Prices Realized:

  • Search by cert number
  • Use a coin holder's barcode
  • Find with PCGS number and grade
