The request and response formats follow the Gemini specification; authentication uses the `x-goog-api-key` header (carried by Gemini SDK by default). Existing Gemini SDK can be accessed by simply replacing the baseURL and API Key, and billing is based on AiToEarn points. Before calling this interface, please request the ["Conversation Model List"](/en/api-reference/get-api-ai-models-chat) interface (`GET /api/ai/models/chat`) to obtain the currently available model list. ## OpenAPI ````yaml /openapi/en/aitoearn.openapi.json post /api/ai/v1beta/models/{model}:generateContent openapi: 3.0.1 info: title: AiToEarn Open Platform API description: >- AiToEarn Open Platform API.
