Gemini Native (Image)

Invoke the AboAI API using the Google Gemini native format

Introduction

The Gemini Native API utilizes Google Gemini's request and response formats, making it suitable for official Google clients (such as the google-generativeai SDK) or scenarios that require direct use of Gemini data structures. This interface complies with the Gemini API specifications and fully supports features such as Thinking mode, multimodal input, tool calling, Google Search (Grounding), and image generation.

API Endpoints

Feature	Method	Path
Content Generation (Non-streaming)	POST	`/v1beta/models/{model}:generateContent`

Authentication

Supports either of the following methods:

Header Parameter	Type	Description
`Authorization`	string	Bearer Token: `Bearer sk-xxxxxxxxxx` (Recommended, consistent with other AboAI interfaces)
`x-goog-api-key`	string	Google-style API Key: `x-goog-api-key: sk-xxxxxxxxxx`

You can also pass the parameter via the URL: ?key=sk-xxxxxxxxxx.
