Operations
| Operation | modelId | Endpoint | Required input |

| Poll task | — | GET /api/v1/task/{id}?model=gemini-2-5-pro | — |
Input parameters
| Field | Type | Required | Values / example |
|---|---|---|---|
| prompt | string | Yes | Text value (example: Explain to a curious teenager why some ocean waves glow electric blue at night, in three vivid and scientifically accurate sentences.) |
| structured_outputs | boolean | No | Generate structured outputs (true/false) (example: false) |
| reasoning_effort | string | No | Control reasoning depth: Low for faster responses, High for deeper analysis (options: Low | High) (example: High) |
| stream | boolean | No | Turn off to get a single non-streaming response. (true/false) (example: true) |
| system | string | No | System instruction for the model. Defaults to "You are Gemini 2.5 Pro, developed by Google." when omitted. |
| messages | array | No | A conversation instead of a single prompt: an array of { "role", "content" } objects, where role is user, assistant or system. Send the whole conversation — we do not limit how many messages it has, and we do not drop old ones; the model's context window is the limit. Send prompt or messages, not both. Do not flatten a conversation into one prompt with "User:" / "Assistant:" labels — the model reads that as a single message, and a model using web search then searches for the whole block instead of your question. |
