# OpenAI API The OpenAI API is the programmable interface through which software can submit requests to OpenAI models and receive model outputs. It separates model capability from any one website or application interface. ## Notebook evidence PDF page 1 of [[Scanned_20260730-1845]] places “API” beside OpenAI, GPT-3, Playground, free credit, and account creation. Page 3 states `open AI query is platform`, moving from API onboarding toward a larger orchestration model. ## Cross-notebook significance The API is the bridge between generative interface and cloud execution. In the notebook's emerging architecture, it could sit above Oracle/Ubuntu/LAMP services, domains, identity providers, and an eventual [[Knowledge Graph]]. ## Boundary The notes do not preserve an API key, application, request log, or deployed integration. Any credential-equivalent material remains outside the public graph and must never be tested. ## Source - [[Scanned_20260730-1845]], PDF pages 1 and 3.
