You can access the Venice API in two ways. The standard way is to create an API key in your API Dashboard at https://venice.ai/settings/api, then use the API with your available USD credits or DIEM. Venice also supports x402, an alternative that uses wallet authentication instead of an API key. The API is compatible with the OpenAI SDK: set the base URL to https://api.venice.ai/api/v1 and use your Venice API key with a Venice model ID.
