SwissAI API

快速上手

三步获得第一个响应：

1. 在开发者控制台的 API Keys 下创建密钥。它仅显示一次——请妥善保存。格式：sk-souheng-…

2. 向 chat 端点发送请求：

curlcurl -N https://api.swiss-ai.one/api/v1/external/chat/completions \
  -H "Authorization: Bearer sk-souheng-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "messages": [{ "role": "user", "content": "用瑞士德语打个招呼。" }],
    "stream": true
  }'

3. 你会收到一个兼容 OpenAI 的 SSE 流（见流式）。

身份验证

每个请求都用你的 API 密钥在 Authorization 头中进行身份验证：

httpAuthorization: Bearer sk-souheng-YOUR_KEY

API 密钥仅在门户中管理（创建、列出、撤销）。每个账户最多 20 个有效密钥。

基础 URL

POST/api/v1/external/chat/completions

生成一条 chat 响应。默认开启流式。

请求体

流式 (SSE)

当 "stream": true 时，API 以 OpenAI chunk 格式返回 text/event-stream。流以 data: [DONE] 结束。

ssedata: {"id":"chatcmpl-1a2b3c4d","object":"chat.completion.chunk","created":1750000000,"model":"swissai","choices":[{"index":0,"delta":{"content":"Hallo"},"finish_reason":null}]}

data: {"id":"chatcmpl-1a2b3c4d","object":"chat.completion.chunk","created":1750000000,"model":"swissai","choices":[{"index":0,"delta":{"content":"!"},"finish_reason":null}]}

data: {"id":"chatcmpl-1a2b3c4d","object":"chat.completion.chunk","created":1750000000,"model":"swissai","choices":[{"index":0,"delta":{},"finish_reason":"stop"}]}

data: [DONE]

非流式

当 "stream": false 时，你会收到单个 chat.completion 对象：

json{
  "id": "chatcmpl-1a2b3c4d",
  "object": "chat.completion",
  "created": 1750000000,
  "model": "swissai",
  "choices": [
    {
      "index": 0,
      "message": { "role": "assistant", "content": "你好！有什么可以帮你的？" },
      "finish_reason": "stop"
    }
  ]
}

工具 / 函数调用

以 OpenAI 格式传入工具。模型调用工具时会返回 tool_calls（流式与非流式相同）。把结果作为带有对应 tool_call_id 的 tool 消息发回。

json{
  "messages": [{ "role": "user", "content": "苏黎世天气怎么样？" }],
  "stream": false,
  "tools": [{
    "type": "function",
    "function": {
      "name": "get_weather",
      "description": "城市的当前天气",
      "parameters": {
        "type": "object",
        "properties": { "city": { "type": "string" } },
        "required": ["city"]
      }
    }
  }],
  "tool_choice": "auto"
}

Python

requests（流式）

pythonimport json, requests

resp = requests.post(
    "https://api.swiss-ai.one/api/v1/external/chat/completions",
    headers={"Authorization": "Bearer sk-souheng-YOUR_KEY"},
    json={"messages": [{"role": "user", "content": "你好"}], "stream": True},
    stream=True,
)
for line in resp.iter_lines():
    if not line:
        continue
    line = line.decode()
    if line.startswith("data: "):
        data = line[6:]
        if data == "[DONE]":
            break
        delta = json.loads(data)["choices"][0]["delta"]
        print(delta.get("content", ""), end="", flush=True)

JavaScript / Node

javascriptconst res = await fetch(
  "https://api.swiss-ai.one/api/v1/external/chat/completions",
  {
    method: "POST",
    headers: {
      "Authorization": "Bearer sk-souheng-YOUR_KEY",
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      messages: [{ role: "user", content: "你好" }],
      stream: true,
    }),
  }
);

const reader = res.body.getReader();
const decoder = new TextDecoder();
let buffer = "";
for (;;) {
  const { done, value } = await reader.read();
  if (done) break;
  buffer += decoder.decode(value, { stream: true });
  const lines = buffer.split("\n");
  buffer = lines.pop();
  for (const line of lines) {
    if (!line.startsWith("data: ")) continue;
    const data = line.slice(6);
    if (data === "[DONE]") { reader.cancel(); break; }
    const delta = JSON.parse(data).choices[0].delta;
    if (delta.content) process.stdout.write(delta.content);
  }
}

OpenAI SDK

现有的 OpenAI SDK 只需设置 base_url 和 api_key 即可使用。model 是 SDK 必填字段，但服务端会忽略它。

pythonfrom openai import OpenAI

client = OpenAI(
    api_key="sk-souheng-YOUR_KEY",
    base_url="https://api.swiss-ai.one/api/v1/external",
)

stream = client.chat.completions.create(
    model="swissai",  # 任意值——会被忽略
    messages=[{"role": "user", "content": "你好"}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

javascriptimport OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-souheng-YOUR_KEY",
  baseURL: "https://api.swiss-ai.one/api/v1/external",
});

const stream = await client.chat.completions.create({
  model: "swissai",            // 任意值——会被忽略
  messages: [{ role: "user", content: "你好" }],
  stream: true,
});
for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}

计费与限制

• 请求按 token 从你的余额（wallet）计费。
• 余额和用量可在控制台查看，也可在那里充值。
• 每个账户最多 20 个有效 API 密钥。
