Wholesale Market Price API for Octopus Customers

Octopus Energy now offers an API that serves up current wholesale prices across ERCOT. For our customers who use the wholesale price to automate their home, customers who would like to track the price outside our app, or simply the curious, this API is another tool Octopus offers to monitor the real-time power markets.

You can explore the API documentation through the link below.
