Authentication

W&B API key api_key discovered Get key ↗

Authorization: Bearer <credential>

Create a personal or service-account API key in W&B. The quickest path is Authorize or User Settings: sign in, create a new API key, and copy it immediately because W&B only shows the full key once. For service-account-owned keys, use the Service Accounts area described in the W&B Quickstart. Store it as WANDB_API_KEY or pass it as a bearer token where supported.
