Make Your First Request

You send the conversation so far as a list of messages; the model appends its reply. Non-streaming returns the whole reply as one JSON document. For piece-by-piece delivery, see Stream Your First Response.

The Python and TypeScript examples use the official OpenAI SDK pointed at Nito. For most apps the change is the base URL and the key.

Request Fields

Field	Type	Required	Meaning
`model`	string	optional	The model ID. Omitted, a default model is used. Add `:confidential` for the attested variant.
`messages`	array	required	The conversation. Each item is `{ role, content }`. Roles: `system`, `user`, `assistant`, `tool`, `developer`.
`temperature`	number	optional	Sampling randomness. Forwarded to the model.
`top_p`	number	optional	Nucleus sampling.
`max_tokens`	integer	optional	Cap on generated tokens. `max_completion_tokens` is the newer name.
`stream`	boolean	optional	`true` streams Server-Sent Events. Default `false`.

system (or developer) sets instructions, user is the human turn, assistant replays a previous model turn, and tool carries a function result and must reference its call via tool_call_id. Name a model explicitly so behavior does not change when defaults change.

Response

{
  "id": "...",
  "object": "chat.completion",
  "created": 1751299200,
  "model": "z-ai/glm-5.2",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "1. Your prompts stay private. 2. ... 3. ..."
      },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 28,
    "completion_tokens": 64,
    "total_tokens": 92
  }
}

choices[0].message.content is the answer. There is exactly one choice.
finish_reason: stop, length (token cap), tool_calls, or error.
usage: prompt_tokens, completion_tokens, total_tokens. Reasoning models add reasoning_tokens.
system_fingerprint is always null.

Attested Hardware

{ "model": "z-ai/glm-5.2:confidential", "messages": [ ... ] }

Nothing else changes. A model that cannot serve the level is rejected. Afterwards, fetch and verify the attestation evidence: How Attestation Works, attestation endpoint.

Errors

Empty messages. At least one is required.
A tool message without tool_call_id.
Expecting several choices. Nito returns one. For several models on one prompt, use Model Fusion in the Browser App or Plugin.
