Is there a different API Key?

ChatGPT is telling me to ask this:
Hi, I'm building a WordPress plugin that uses the /talks API endpoint with Express Avatars. I need a server-side REST API key to generate videos from text. Can you please enable API access for my account? It is supposed to start with did_live_xxxxx. My API key just starts with letters and numbers. How do I get a REST API key for server side access and not just a Web SDK token?
