官网链接

首次调用 API | DeepSeek API Docs

curl https://api.deepseek.com/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <DeepSeek API Key>" \
  -d '{
        "model": "deepseek-chat",
        "messages": [
          {"role": "system", "content": "You are a helpful assistant."},
          {"role": "user", "content": "Hello!"}
        ],
        "stream": false
      }'

可见需要两个参数：Content-Type 和 Authorization

输入

{
  "messages": [
    {
      "role": "system",
      "content": "I'm researching developer tools and I need the shortest answers possible"
    },
    {
      "role": "user",
      "content": "What does Postman do?"
    }
  ],
  "model": "deepseek-chat",
  "temperature": 1,
  "max_tokens": 1000,
  "top_p": 1,
  "stream": false
}
