How to Get an NVIDIA NIM API Key

Log in to NVIDIA Build, open API Keys, and generate a key for API calls

NVIDIA Build provides model demos and API access for NVIDIA NIM. Page labels may change over time; follow the current build.nvidia.com UI. Never expose your API key or commit it to a public repository.

1. Open NVIDIA Build and log in

Go to NVIDIA Build and follow the prompt to sign in to NVIDIA AI. First-time users can continue with an email address or create an account. The page highlights free serverless APIs for development and the option to self-host on your own GPU infrastructure.

3. Generate and manage an API key

On the API Keys page, click Generate API Key. Copy the full key into the app, environment variable, IDE plugin, or script that will call NVIDIA NIM. If the full key is shown only once, save it immediately in a secure location.

Security tip: Do not put API keys in public repositories, screenshots, or chat messages. If a key may have leaked, revoke it in NVIDIA Build and generate a new one.
