    API

    An interface for programs to call AI models or services programmatically.

    What is API?

    An API (Application Programming Interface) is the way one program talks to another. AI APIs (Claude API, OpenAI API, Gemini API) let you embed LLM capabilities into your own apps and workflows. Authentication is via API keys; pricing is usually per-token. ONROL teaches API basics in the Orchestrator track.
