FAQ
Do I need to provide my own API key?
Yes. You provide your OpenAI or Anthropic API key, and I integrate it into your application securely (stored as an environment variable, never logged or committed). This gives you full control over costs and usage limits. If you have not signed up yet, I can walk you through setup in chat.
