Question about GPT and API key help

I have created several GPT’s and I am now considering making a few of these available. I am new to API’s and I have read several different answers to this question. But can I use an API key to my GPT prompts?

Hi and welcome to the Developer Forum!

GPTs and the API are not in the same ecosystem and do not generally interact, so an API based application cannot interact with a GPT.

GPTs are “no-code” ways to create specialised AI’s for tasks you and possibly others find useful. although some degree of technical knowledge will improve your ability to create more complex GPTs.

A correctly configured GPT could make use of an API endpoint as part of an API enabled service that has been created, but you would need to build that application first.
