Operations
| Operation | modelId | Endpoint | Required input |

| Poll task | — | GET /api/v1/task/{id}?model=gpt-5-2 | — |
Input parameters
| Field | Type | Required | Values / example |
|---|---|---|---|
| prompt | string | Yes | Text value (example: Draft a warm, friendly three-sentence welcome message for a new member joining a downtown coworking space.) |
| memory | boolean | No | Automatically append previous messages to maintain multi-turn context. May increase token usage. (true/false) (default: false) |
| reasoning_effort | string | No | Control reasoning depth: Low for faster responses, High for deeper analysis (options: Low | High) (default: High) |
| system | string | No | System instruction for the model. Defaults to "You are GPT-5.2, developed by OpenAI." when omitted. |
| messages | array | No | A conversation instead of a single `prompt`: up to 20 objects of { "role", "content" }, where role is user, assistant or system. 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. |
