    快速开始

    可直接粘贴运行下方示例代码。Gate.AI API 与 OpenAI 兼容,多数 SDK 只需替换 base URL;切换模型时,只需修改模型 ID。

    1

    Get your API key

    Sign in to the Gate.AI console and create a new key under "API Keys". Keep it safe and send it via the Authorization header on every request.

    前往控制台创建密钥
    2

    Make a request

    Send a POST request to the Chat Completions endpoint with a model ID and an array of messages to get a reply.

    POSThttps://api.gate.ai/openai/v1/chat/completions
    curl --location "https://api.gate.ai/openai/v1/chat/completions" \
      --header "Authorization: Bearer {API_KEY}" \
      --header "Content-Type: application/json" \
      --data '{
      "model": "glm-5.3-flash",
      "messages": [
        {"role": "user", "content": "Hello"}
      ]
    }'

    Handle the response \\\\\& streaming

    By default a full JSON response is returned. Add "stream": true to the request body to receive incremental chunks over SSE.

    POSThttps://api.gate.ai/openai/v1/chat/completions
    curl --no-buffer --location "https://api.gate.ai/openai/v1/chat/completions" \
      --header "Authorization: Bearer {API_KEY}" \
      --header "Content-Type: application/json" \
      --data '{
      "model": "glm-5.3-flash",
      "messages": [
        {"role": "user", "content": "Hello"}
      ],
      "stream": true
    }'

    端点

    基础 URL、请求方法和必需请求头均按当前模型的协议模板渲染。
