I was playing with this idea a bit last week, threw together this example.
I don’t know how companies would feel about an Open LLM having access to all their private family jewels but the concept is definitely intriguing. The incredible thing about this is that since Chat GPT already “knows” the Open API Specification all I had to do was point it to / tell it where to find my Epicor API, I only gave it access to 2 BAQs zCustomer01 and CustomerTotalSales (SUM(InvoiceHead.InvoiceAmt) generated a SWAGGER Specification for them
and off to the races! Since it consumes Open API though you could just point it straight at your Epicor API… but that seems like a lot of Trust!
