Log in to Console - Security Authentication - API Key, then click Create API Key. The created API Key can be used for Qianfan AppBuilder, ModelBuilder, and AI Open Capabilities.

Once you have an API Key, send your first request with a REST client, the official Qianfan SDK, or an OpenAI-compatible SDK. Refer to the Model List to select the model parameter.
