Venice Authentication

Every Venice endpoint accepts one of two auth schemes, declared in the OpenAPI spec as BearerAuth and siwx. Both are first-class — pick whichever fits the deployment.

Use when

• You're making your first call to api.venice.ai.
• You're building a server-side integration (usually Bearer) or an agent / no-account wallet flow (x402).
• You hit 401 Authentication failed and need to check header format.
• You're implementing SIWE signing manually instead of using the SDK.

Option A — Bearer API key

Authorization: Bearer <VENICE_API_KEY>
